LED、PWM调光的原理
1. 芯片的工作频率是指正常工作时候的频率,当调光输入为低电平时候要分情况;
2. LED恒流驱动如果是真正的PWM控制方式,则调光低电平来临的时候,恒流芯片不工作;
3. 当LED驱动为恒定开启时间,或者恒定关闭时间控制方法的时候,当调光低电平来临的时候,芯片还是会按照即定的频率来开关,但占空比会发生很大变化,即变的非常小

IntroductionThe H-10 Pro is the most versatile, high performance leak detector available in the industry today. It detects refrigerants to pinpoint small, medium, and large leaks quickly and efficiently. Review this manual carefully and completely to assure satisfactory product performance and a long service life.1.2. Safety Warnings! WARNING: For your safety, DO NOT use this device to detect for leaks of refrigerants which are rated as combustible/flammable gases (e.g., ASHRAE A2- or A3-rated refrigerants).!HAZARDOUS AREA WARNING: This instrument has not been designed to be intrinsically safe for use in areas classified as hazardous locations. For your safety, DO NOT use it in hazardous (classified) locations.1.3. General Warnings!WARNING: This device is not to be used in any application that is beyond its intended purpose or beyond the scope of its specifications. For details on appropriate use, refer to the rest of this manual. Before risking equipment damage or personal injury, contact Bacharach if you are unsure of the validity of a particular application.!IMPORTANT:This analyzer is not intended to be used on a continuous basis.!WARNING:Except for replacement of consumables such as sensors, filters, and battery, this analyzer should only be opened and/or serviced by authorizedBacharach personnel. Failure to comply may void the warranty.!WARNING: Do not store instrument or its sensors with solvents or products that contain solvents.!IMPORTANT:Equipment Damage HazardsA.Submerging the probe in liquid willdamage the pump.B.Exposing the probe to pure refrigerantwill severely reduce the life or destroy the sensor. Life of the sensor is directly proportional to the amount of refrigerant that it is exposed to.C.Exposure to high concentrations ofrefrigerant may require adjustment of sensor heat. Refer to section 3.1.1.4. Specifications[1]Based on normal use. Consistent and/orconstant exposure to high levels of refrigerantwill deteriorate the sensor life more quickly.Increasing the sensor heater will also impactsensor life.[2]DO NOT use this device to detect for leaks ofrefrigerants which are rated as combustible/flammable gases (e.g., ASHRAE A2- or A3-ratedrefrigerants).[3]Sensitivity for R12, R22, R134a, R410a, R404a andR507 when unit is set to small leak setting,manual mode.[4]This warranty does not cover sensors, referenceleaks, filters, airflow balls, lamps, batteries, orprobe tips. This warranty does not coverdamages caused by the user.∇∇∇Section 2. Operation2.1. OverviewThe H-10 Pro sensor uses positive ion emission technology, commonly known as a heated diode. It is very sensitive to only halon substances (refrigerants) making this product highly resistive to false alarming, while retaining superior sensitivity for pinpointing the most difficult to find refrigerant leaks.A pump inside the unit draws air through the probe to the sensor. The presence of refrigerant(s) causes the H-10 Pro to sound a speaker and illuminate an LED in the probe. Sensitivity to pinpoint small, medium, and large leaks can be controlled by setting the Leak Size switch (see Section 2.2).2.2. Panel Controls2.3. Before First Use…Before you use the unit the first time: 1.Remove the sticky-label disc from thecap of the calibration reference bottle.This disc can be reused to help seal the vial when the leak detector is not in use, or it can be discarded. DO NOT attempt to unscrew the cap, you may damage the bottle. The calibration reference bottle should last approximately six months.2.With the Power switch in the OFFposition, charge the battery using the wall adapter. Charge time is 3-4 hours or until the Full Charge LED turns green.2.4. Adjusting the SensitivitySet the Leak Size switch as follows.SMALL switch position is the highest sensitivity. The unit will indicate leak rates of 0.006 oz/yr or greater and is used for fluorine-based (HFC) gases like R134a. This position also assures highest repeatability for locating 0.1 oz/yr (or greater) leaks per SAE J2791 moving probe test conditions. It must always be used to verify performance and calibration when using the calibration reference bottle.When using the small leak range position, a leak of HFC causing an audible signal equal to that produced by the leak vialhas a leak rate of approximately 0.5 oz/year.MEDIUM switch position is used for chlorine-based (CFC and HCFC) gases like R12 and R22. The medium setting will indicate approximately a 0.1 oz/yr (or greater) leak rate. This position supports finding leaks of approximately 0.5 oz/yr (per SAE J2791) or greater. It is also useful for locating larger HFC leaks.When using the medium leak range position on a CFC or HCFC system, this leak rate would also be approximately 0.5 oz/year.LARGE switch position is used to zero in on large leaks of any refrigerant. The large leak setting should be used in conjunction with manual mode.2.5. Auto Mode vs. Manual ModeAuto mode enables the H-10 Pro to block out background levels of refrigerants. This greatly reduces and/or eliminates false alarms while retaining sensitivity to quickly locate small or medium size leaks. Pinpointing leaks in this mode requires continuous probe movement.If the probe is held stationary over a leak, the unit will zero out the leak, going into the idle 1 tick/second condition. Briefly moving the probe away from the leak (1-2 seconds) permits the unit to re-establish sensitivity. Returning to the leak site, the unit will alarm again. Continuing thisprocedure will reliably and repeatedly pinpoint the leak with each pass over the leak site.If a large leak is present, the auto zero circuit may reduce sensitivity to an unacceptable level to find small and medium sized leaks. If this condition exists, use the manual mode to pinpoint a large leak. The manual mode is also an effective means to determine if a large leak of any refrigerant exists prior to searching for leaks (see Section 2.4).In Manual Mode the auto-zero circuit is disabled. The unit will not zero the leak if the probe is held over the leak site. This mode may require frequent readjustment of the Manual Balance control to maintain the required 1 tick per second that indicates proper adjustment and calibration for all three sensitivity switch positions. Manual mode provides greater sensitivity than auto mode.2.6. Setup1.Turn the unit on.2.Slide mode switch to AUTO position.3.Slide the sensitivity switch to theSMALL position.4.Check Low Battery LED. If it glows red,the battery needs charging, or youmay operate the unit using the supplied wall adapter.!NOTE: The sensor does not operate when the low battery LED is on.5.Check for sufficient airflow by pointingthe probe tip toward the floor, covering it with your finger, then releasing your finger. If proper flow exists, the red ball should noticeably rise up into the probe when you uncover the probe tip. Note that the actual height and final resting position of the red ball are not important. If the airflow ball does not rise:a.Tap the probe lightly to ensure theball is not sticking.b.Check the filter in the probe tip,per Section 4.1. If the flow is stillinsufficient, then the unit shouldbe sent for repair to the nearestAuthorized Service Center.6.Allow two minutes for the sensor towarm up, after which the flashing probe light and sound indicator will idle at approximately 1 click per second.7.Test operation by quickly touching theprobe tip to the top of the calibration reference bottle (make sure sticky label is removed). The unit should respond with a rapid flash rate and sound verifying correct operation and optimum sensitivity. If the unit does not respond correctly, see Section 3.1.2.7. Checking for Leaks! SAFETY WARNING: For your safety, DO NOT use this device to detect for leaks of refrigerants which are rated as combustible/flammable gases (e.g., ASHRAE A2- or A3-rated refrigerants). 1.Set the range switch to theappropriate range to ensuremaximum sensor life. If the leak sizeis unknown, start at the Large leaksetting. This protects the sensor if alarge amount of gas is present.!IMPORTANT:Exposing the sensorto large amounts of refrigerant orholding the probe over a leak for along period of time will significantlyshorten sensor life.2.Check for leaks in a logicalprogression through the entiresystem.3.If surfaces are dirty or wet, wipethem off with a clean, dry cloth toreduce filter clogging and extendsensor life. DO NOT allow the unit todraw in moisture. Use of the suppliedrubber probe tip helps preventmoisture from being drawn into theunit. Check for moisture beforeinserting the probe into areas to bechecked for leaks.4.If leaks have not been detected usingthe large leak setting: Try using themedium or small setting asappropriate.If leaks have been detected using thelarge leak setting: After locating andrepairing any leaks requiring the useof the LARGE switch setting, switchto the MEDIUM setting and verify thesystem is free of leaks. For HFCrefrigerants (such as R134a), verifythe system is leak free using theSMALL setting. For CFC and HCFCsystems (such as R12 and R22), theMEDIUM setting is typically sufficientto verify that the system is free ofleaks that require repairing.After a leak is located and repaired,clear the area with shop air, set theunit on the small leak sensitivity, anddouble check equipment for smallleaks.∇∇∇Section 3. Calibration andPerformance3.1. Heater AdjustmentsThe sensor heater circuit can be adjusted to control the sensitivity of the unit. A heat setting that is too high causes instability due to excessive sensitivity and shortens sensor life. A heat setting that is too low causes decreased sensitivity. The heater adjustment LEDs, heater adjustment, and calibration reference bottle is a unique system for setting the correct sensor heat (sensitivity) for optimum performance and long sensor life. To check the heater setting:1.Slide the mode switch to AUTO, slidethe leak switch to SMALL, turn ONthe unit and allow it to stabilize(approximately 2 minutes).2.When stabilized (at approximately 1click per second), briefly touch theprobe tip to the calibration referencebottle with the probe (ensure thesticky label disc is removed from thetop of the bottle.3.If adjusted properly, the red LOWLED will go out and the green OK LEDwill briefly glow. This indicates thesensor’s heat/sensitivity is adjustedfor optimum performance.If the red LOW LED remains on whenyou briefly touch the bottle, thesensor heat is set too low and theHeater Adjustment must be turnedslightly clockwise using a smallscrewdriver. Allow unit to stabilizeabout one minute and retest. Repeatthis procedure until the green OK LEDbriefly glows.If the red HIGH LED glows, the heat isset too high and the heateradjustment should be turned slightlycounterclockwise using a smallscrewdriver. Allow the unit tostabilize for about 1 minute and thenrepeat the test. Repeat thisprocedure until the proper green OKLED is indicated.!NOTE:After initial check for correct heater adjustment, disregard the calibration LEDs. Their indication is meaningless during subsequent leak testing activity.!NOTE:Check for proper heat adjustment on a daily basis. This assures the H-10 Pro is calibrated for the correct sensitivity for your daily test activity.!NOTE:Frequency of sensor heat adjustment is a function of how much exposure the sensor has to refrigerant. Adjustment may be required every couple of weeks for heavy duty service and once every few months for light duty service. !NOTE:Over the usable sensor life, when heater adjustment is fully clockwise and the green OK LED will not come on, it is time to replace the sensor. (See Section 4.3.)∇∇∇Section 4. Maintenance4.1. Replacing the FilterTo protect the pump from damage due to foreign particles and moisture, replace the filter as it becomes dirty. With moderate use (15 to 30 minutes a day), it is recommended that the filter be replaced once per month. In dirty environments or with heavy use, replace the filter more frequently. Always replace the filter when it is visibly dirty or wet. To replace the filter, follow the steps below.1.Remove the black rubber probe tip.2.Pick out the filter with a pin ortweezers. A fine screen will remain in the tip of the probe nozzle (behind where the filter sits).3.Insert the new filter in the probe tip.Make sure that the filter is firmly seated against the screen.4.Replace the rubber probe tip.4.2. Replacing the Airflow Indicator1.Remove the clear plastic section of theprobe tip by gently pulling and twisting.2.Turn the probe tip upside-down andtap on it to remove the old airflow indicator ball.3.Insert the new airflow indicator ballinto the tip.4.Reattach the probe tip to the probeassembly.4.3. Replacing the SensorThe sensor needs to be replaced when the H-10 Pro no longer responds to the calibration reference bottle, even with the heater adjustment turned fully clockwise (make sure the reference bottle contains some refrigerant).1.Turn the leak detector OFF.2.Turn the heater adjustment to itsfull counterclockwise position.3.Unplug the power cord and openthe sensor cover.4.Allow the sensor to cool beforetouching it.!WARNING: Sensor temperaturemay cause a burn if not allowed tocool.5.Unplug and discard the sensor.6.Insert a new sensor and close thesensor cover.7.Adjust the heater per Section 3.1.∇∇∇Section 5. Troubleshooting 5.1. Diagnosing IssuesP=Problem C/S=Cause/Solution(s) P No response to calibration reference bottle.C/S Heat Adjustment is set too low or bottle is empty. Readjust heater (see“Heater Adjustment” section) orreplace bottle (3015-0864).No air flow (indicator ball in probedoesn’t float). Replace filter in probetip (3015-0784). Check for properpump operation.Sensor exposed to excessive amountsof halogen gas. Move probe to cleanatmosphere for several minuteswhile sensor purges itself.Water is in the probe. Turn unit offand disconnect probe from chassis.Remove screws and take out chassis.Look at the underside of the leakdetector and follow the probe to thepump. Remove this hose from thepump. Blow clean air (5 psi) into theprobe tip for one or two minutes.Reassemble unit and replace thefilter (3015-0784).P Erratic response occurs in all leak positions.C/S Filter is clogged. Replace the filter (3015-0784).Dirt is in the sensor. Remove sensorand blow it out with clean air (notover 10 psi). If unsuccessful, replacethe sensor (3015-0486).
