激光准直仪操作规程激光准直测量系统由半导体激光器、光学分光及转向系统、光电接收系统及液晶显示模块组成。
激光光束经转向系统后出射两条相互平行的基准光束,作为导轨的安装检测基准。
该系统利用二维PSD作为光电接收器件,采用液晶显示模块显示导轨偏差,可快速、直接、准确地测量导轨安装的偏移量,从而提高导轨安装的精度和速度。
实验结果显示测量系统在X,Y方向上的标准偏差分别为：0.002mm,0.005mm。
1、主要参数2、主机由半导体激光器、空间位相调制器、壳体、底座、和电源所组成。
3、激光准直仪的特点与工作原理1）仪器的特点是采用了空间位相调制器。
激光束在任意测距上，其横截面均为一组良好的、红黑反差很大的同心圆环，中心光斑亮且小，利于定位。
而且在不同测距进行测量时是不用调焦的，实现了无调焦运行差。
中心光斑直径随着工作距离的增大而增大，符合下列参数:L=2.5米时Ø0.1mmL=20米时Ø1.2mmL=50米时Ø2.5mm2）将仪器固定在主机的回转轴上后用百分表测量仪器端部的测环在盘车处于不同位置时的差值，通过调整仪器底座上的调整螺钉，使其差值越来越小，只要主机轴系配合良好，可以调至±0.02~0.03mm。
然后利用置于远离主机15米左右的平面反射镜，将仪器射出的激光束反射至位于仪器附近的测微光靶。
在主机盘车时调整仪器壳体上的四只调整螺钉，（必要时适当调整反射镜的角度），使反射回来的激光束画的圆的半径越来越小，最后调至±0.1mm以内为止，此时应再次检查盘车360°时，百分表所显示波动值的范围和测微光靶的测量差值，准确无误时即可用此光轴代替主机的机械轴。
3）二维测微光靶二维测微光靶是用来记录与测量主机盘车时光轴的变化量。
二维测微光靶是由光靶和在X、Y两个自由度上测微的百分表所组成，光靶本身带有卡具和折射棱镜，为安装和读数提供了方便条件。
测微光靶的工作范围是±4.5mm。

TriAngleElectronic Autocollimator for Precise Angle MeasurementLEADING TO THE FUTURE OF OPTICSOptical systems have changed the world.And they will continue to do so.TRIOPTICS is significantly involved in this process.We see ourselves as a solution provider for optical measurement and manufacturing systems andoffer our customers the right system for their current and future applications.2Key FeaturesTriAngle Electronic Autocollimators• Electronic Autocollimators for Optical Angle Measurement• Measurement of angular displacements with highest accuracy • Wide range of application specific variants with a modular design • Effective focal lengths from 100 – 1000 mm• Different sensors, reticles and light sources available• Accuracy performance up to 0.05 arcseconds• OptiAngle Software package for angle measurements4IlluminationFilter Condensor Object ReticleDiffusorObjective LensSensorBeam SplitterDigital CameraPrinciple of an Electronic AutocollimatorThe autocollimator combines both optical tools, the collimator and the telescope into one instrument using a single objective lens. Both beam paths are seperated by using a beam splitter. The autocollimator is a very sensitive angle measuring device and is thus used for the precise angular adjustment of optical or machine components. Due to the collimated beam (infinity adjustment) the measurement results are independent from the distance to the object under test.In an electronic autocollimator the eyepiece is replaced by an electronic camera with discrete sensor pixels (e.g. CCD or CMOS sensor type). It can be of a 2D frame type allowing angular measurements in two directions, or a 1D line scan sensor for single axis measurements. The digital camera is usually connected to a PC which calculates the measured angle from the image by using image analysis software. The high resolution of electronic autocollimators is due to the evaluation of gray scale levels in the image which allows for sub pixel interpolation of the image position. Depending on the focal length of the objective lens and the stability of the setup, angular resolutions of 1/100 up to 1/1000 arcsecs can be achieved.TriAngle Electronic AutocollimatorThe TriAngle electronic autocollimators are non-contact optical test tools for thehigh-precision measurement of angular displacements of specular reflective surfaces andthe accurate angular alignment of optical or mechanical parts.TriAngle autocollimators have a versatile modular design which allows them to be fitted with a wide selection of objective tubes, different sensors, reticles and light sources.

Using patented technology, the Tru Pointe® Ultra guides the user to a leak by quantifying the intensity of the ultrasound and converting it to sound the user can easily hear. The Tru Pointe® Ultra has been specifi cally designed for air conditioning and refrigeration (HVAC-R) leak detection. The Tru Pointe® Ultra is the only test system that can simultaneously detect the vacuum and high pressure leaks that can occur in HVAC-R systems. Since the instru-ment detects only sound, it is gas-independent and can be used to detect leaks at the speed of sound, without the delay seen with gas dependent “sniffers.”What’s in the Kit0028-8000Tru Pointe® Ultra KitTru Pointe® Ultra .......................0028-7000 Instruction Manual ....................0028-9000 Carrying Case...........................0028-0005 6” Wave Guide ..........................0028-0004 Touch Probe .............................0028-0003 Folding Hi-Fi Headsetw/ Volume Control ....................0028-0002 9v Battery .................................0204-0024 Warranty Card ..........................0006-88250028-8010Tru Pointe® Ultra Kit w/ SoundBlaster®Tru Pointe® Ultra .......................0028-7000 SoundBlaster® ..........................0028-7006 Instruction Manual ....................0028-9000 Carrying Case...........................0028-00056” Wave Guide ..........................0028-0004 Touch Probe .............................0028-0003 Folding Hi-Fi Headsetw/ Volume Control ....................0028-00029v Battery .................................0204-0024 Warranty Card ..........................0006-8825Features• Capable of detecting a 5 psi leak from a .005” hole from 20-30 feet (depending on back-ground noise.• Capable of detecting any gas that generates ultrasonic sound during fl ow, including vacuum leaks.• Not affected by wind or high concentrations of leaked refrigerants.• SoundBlaster® allows testing of items not under pressure. (0028-8010 only)23 Specifications34 OperationPhysicalTo begin using the Tru Pointe® Ultra, fi rst take a moment to become familiar with the unit’s controls in Figure 1 and 2.Figure 1.Figure 2.Taking ReadingsGeneral1. Put on the Headphones and plug them into the Headphone Jack on the right sideof the detector.2. Slide the Sensitivity Adjust toward the top of the instrument until it stops. The TruPointe® Ultra is now at full sensitivity.NOTE: Always begin testing at full sensitivity and adjustas needed to reduce background noise.3. Gently push and hold the On/Off Button to begin leak detection. Simultaneouslyadjust the sensitivity level to pinpoint the location of the leak.NOTE: The On/Off Button must be pressed to continueleak detection. Once the On/Off Button is released, thedetector will shut off.4Airborne Leak DetectionThe Tru Pointe® Ultra is capable of detecting airborne leaks from up to 40 feet away. When an ultrasonic signal generated from a leak is detected, it will be indicated by an increase in the LED meter and a rushing sound will be heard in the headset. This sound will become more intense, and the meter reading will increase as the instrument is drawn closer to the leak point.The Tru Pointe® Ultra detects the ultrasound a gas makes as it leaks. Similar to the familiar hiss a leak makes, a gas leak generates ultrasonic sound that humans cannot hear. This ultrasonic sound propagates like a microwave (in straight lines) and this property makes it possible to fi nd its source. It is a listening device not a Sniffer. Because of this, the Tru Pointe® Ultra can function in areas where strong winds or a concentration of fumes are present.A leak is any unwanted fl ow of a substance out of a system, or with vacuum, into a system. The sound made by leaks (refrigerant, compressed air, tire leak etc.) is mostly ultrasonic and cannot be heard by humans.The following describes how to effectively determine the location of an airborne leak using the Tru Pointe® Ultra.1. Press the On/Off Button. If there is signifi cant background noise and the LEDBargraph Display reads ‘10’, reduce the sensitivity until the LED’s disappear.2. While pressing the On/Off Button, scan the area of the suspected leak in a side-to-side motion.3. While scanning, listen to differences in the sounds detected.Mechanical Noise: Usually synchronized to machinemotion in the system and easy to identifyLeak Noise: A harsh hissing sound or bird song.NOTE: To become familiar with the different soundsdetected by the Tru Pointe® Ultra, listen to the sound ofan air hose at low pressure or an aerosol cleaning spray,then shake a set of keys. This demonstration allows theuser to distinguish between mechanical noise and leaknoise.4. If there is leak noise in the area and the display is at ‘10’, slowly reduce the sensi-tivity until the display reads ‘0’.NOTE: The LED Bargraph Display is only for relativemeasurements. If a scan of the system reveals an areawith a reading of ‘2’ and an area with a reading of ‘10’,that can mean the detector is far from a leak, or thereare two leaks of differing sizes in the same area.5. Approach the suspected leak. If the LED Bargraph Display reading increases,reduce the sensitivity.6. When the general location of the suspected leak is determined, adjust the sen-sitivity to so that 4-5 lights are illuminated when the leak area is scanned. Thistechnique allows the user to accurately determine when the instrument is pointedat an area of increased ultrasound. If the LED Bargraph display increases, thenthe leak source is getting closer. If the display decreases, then the leak source isgetting further away.56Operating Tips1.If the test area is large, remove the nose cone. Without the nose cone the detec-tion area of the Tru Pointe ® Ultra increases from 15° to 90°.2. If the leak is in a tight, or inaccessible area, use the supplied Wave Guide to deter-mine the leak location. Longer sections of 1/4” tubing can be used at the expenseof sensitivity.3. When searching for vacuum leaks, you may need to pressurize the system withdry nitrogen to facilitate locating the leak under pressure.4. Use as much pressure as permissible for the system. Increasing the pressure willmultiply fl ow through the same ori fi ce, increasing the ultrasound created by theleak.5.Interference may be experienced from electronic ballasts, computer monitors, orother electronic devices. Place your body between the source of the sound andthe leak point.Electrical ArcingElectrical arcing is an electric current fl ow in air and can be a very destructive and dangerous oc-currence in electrical systems.To search for electrical arcing, use the same methods described to search for airborne leaks, but scan around switches and electrical panels.NOTE: Electrical arcing sounds like frying, including theoccasional popping sound.CAUTION! Observe all all safety precautions whenworking around electrical equipment. Arcing can lead toexplosions.Electrical CoronaElectrical corona is usually observed in higher voltage systems than electrical arcing. Corona usually occurs in insulators, substations or transmission towers.To search for electrical corona, use the same methods described to search for airborne leaks.NOTE: Electrical corona sounds like frying or sizzling.CAUTION! Observe all safety precautions whenworking around electrical equipment.Using the Touch ProbeThe patented Touch Probe accessory is a device that converts solid-borne sounds into airborne sound the Tru Pointe® Ultra can detect. For example, the sound of an internal leak in a water valve will travel to its surface. Touching the surface of the valve with the Touch Probe transfers the ultrasound into the probe and converts it to airborne ultrasound.To install the Touch Probe:1. Unscrew the nose cone from the Tru Pointe® Ultra.2. Screw the Touch Probe onto the sensor.3. The Tru Pointe® Ultra is now ready to detect solid-borne sound.Thermal Expansion Valves (TXV)The following steps can be used to detect leaks in a TXV using the Touch Probe.1. Have a glass of ice water ready.2. Remove the TXV capillary tube.3. Rest the Touch Probe of the Tru Pointe® Ultra on the TXV and listen. Hold thecapillary. The TXV should open and the sound of fl owing refrigerant should beheard.4. Place the capillary in the ice water. The TXV should close and the refrigerant fl owdiminishing should be heard. If the fl ow binds or makes too much noise, theremay be a problem with the system.7Using the SoundBlaster ®Some Tru Pointe® Ultra kits include Bacharach’s ultrasonic sound generator, the SoundBlaster®. The SoundBlaster® is used to artifi cially pressurize items and detect potential leaks using a 115dB ultrasonic tone. The Tru Pointe® Ultra can detect the tone as it escapes in areas that are not under pressure.To use the SoundBlaster®:1. Press the On/Off Button once on the SoundBlaster®.2. Place the SoundBlaster® inside the item to be tested.3. Use the Tru Pointe® Ultra to detect the leaked ultrasonic waves generated by theSoundBlaster® using the same method as detecting a standard airborne leak.NOTE: Using the SoundBlaster® inside a symmetricalobject (i.e. a cylindrical tank) can cause standing waves,which can result in hot and cold spots. For these situa-tions push the ‘Mode’ button to turn the SoundBlaster®’sburst mode on.Tips on Use:1. Sound waves lose strength with distance, so when checking a building for leaks,do not place the SoundBlaster® in the basement and attempt to fi nd leaks in theroof.2. It is best to remove the nose cone from the SoundBlaster® when checking roofs3. If the SoundBlaster®’s tone is too strong, place a piece of sponge or foam in thenose cone.4. DO NOT place the nose cone fl at on a hard surface, as the refl ection of the gener-ated sound could damage the SoundBlaster®.8SoundBlaster® ApplicationsThe SoundBlaster® is an excellent tool for weatherizing buildings by detecting leaks in windows, doors and roofs. To effectively use the SoundBlaster® and Tru Pointe® Ultra to check for building leaks:1. Place the SoundBlaster® in the room to be leak tested and turn it ON2. From outside the room begin scanning for leaks with the Tru Pointe® Ultra aroundthe perimeters of the doors and windows.3. If the Tru Pointe® Ultra reading is at ‘10’, reduce the sensitivity until the detectorreads 4-5 and begin scanning again. Readings above the 4-5 threshold indicate alarger leak and should be fi xed prior to leaks that register under the threshold.4. A clear pattern of high and low readings should develop and pinpoint the locationof the highest priority leaks.Other SoundBlaster® applications include locating, air/water leaks in automobile windshields, trunk seal leaks, truck body leaks, and tanker leaks.95 Care and Service CleaningBoth the Tru Pointe® Ultra and SoundBlaster® can be cleaned using dish soap and a damp cloth. Remove the batteries and close the Battery Door before cleaning. Do not allow water to enter the unit, especially near the sensor. After cleaning, the units can be dried with a paper towel. Any automotive vinyl cleaner will restore the units luster.If you plan to store the units for an extended period, remove the batteries.Battery ReplacementWhen it is time to replace the batteries, use only high quality 9 volt alkaline for both the Tru Pointe® Ultra and the SoundBlaster®, and use the following instructions.1. Hold the unit with the Battery Door facing up.2. Press lightly on the middle of the Battery Door and slide it toward the bottom ofthe instrument.3. Remove the old battery and replace it.4. Slide the Battery Door back on the instrument, making sure it is securely attached.
