» LCD display » Transducer connection Figure 1 Control LocationPower/finefrequency ºButton A ºButton B ºResonanceindicator LED º» Coarsefrequency setJuly 20014502TT-2D USERS MANUAL1.INTRODUCTION 2.CONTROL FUNCTIONS 3.GETTING STARTED 4.HOW IT WORKS 5.CALIBRATION 6.BATTERY TEST 7.SPECIFICATIONS 8.WARRANTY AND REPAIR INFORMATION MONLY ASKED QUESTIONS1INTRODUCTIONThe TT-2D is designed to test acoustic transducers for resonance over the frequency range of 500 Hz to 500 KHz. The TT-2D tests all types of transducers, including transformer-coupled and magnetostrictive devices. The load characteristic (capacitive, resistive, or inductive) and impedance at resonance are displayed on the two line LCD display. The leakage resistance of the transducer can be measured and displayed over the range of 10 ohms to 5 megohms.2CONTROL FUNCTIONSRefer to figure 1 for the location of the controls discussed in this section.2.01TRANSDUCER CONNECTIONThe transducer output connects to the transducer under test. WARNING, donot connect a source of power to this connector. If you do, the TT-2D will be seriously damaged. This is an output only.2.02LCD DISPLAYNormally displays the frequency on the lower line and the impedance andrelative phase on the upper line. Battery voltage and software version aredisplayed for 3 seconds when the power is turned on.2.03COARSE FREQUENCY SET KNOBThis controls the frequency sent to the transducer from less than 500 Hz to over 500 KHz.2.04POWER/FINE FREQUENCY SWITCHThis knob controls the power and is also used to fine tune the frequency setting.The frequency range is about 10% of that set by the coarse frequency control. 2.05BUTTON AThe main function of this push button switch is to select the resistancemeasuring mode. When this button is pressed, the DC resistance of thetransducer is displayed in ohms on the bottom line of the display. The rangecovers 10 ohms to 5 megohms. Press button ‘B’ once to return to normaloperation.2.05.01During power-up, press button ‘A’ to increase the display contrast.2.06BUTTON BThe main function of this push button switch is to select one of the threefrequency ranges. The range increments each time this button is pressed. Each range covers a decade as shown below:2.06.00.01Range 1:500 Hz to 5 KHz.2.06.00.02Range 2: 5 KHz to 50 KHz.2.06.00.03Range 3:50 KHz to 500 KHz.2.06.01During power-up, press button ‘B’ to decrease the display contrast.2.06.02To make a selected frequency range as the default range, selectthe range and before releasing button ‘B’, press button ‘A’.Release both buttons when the display shows ‘FR store’ on thebottom line. This range will be selected each time the TT-2D ispowered-up.2.07RESONANCE INDICATORThis LED brightens when the frequency approaches the resonant point of thetransducer. The brighter the LED, the lower the impedance is. The LED alsoflashes on power-up while the TT-2D initiates the self-test routine.3GETTING STARTEDConnect the TT-2D XDUCER output to a transducer. Turn the power on and the TT-2D will go through a self-test routine while displaying the battery voltage. While the TT-2D is in the self-test mode, the contrast may be set and stored by pressing buttons ‘A’ or‘B’. After the TT-2D displays the frequency on the bottom line, select the appropriate frequency range by pressing button B. Rotate the coarse frequency control while watching the resonance indicator LED for resonant points. There will be three resonance points for most transducers. Choose the one that has the brightest indication on the LED. Fine tune the frequency with the fine frequency control while watching the display for the lowest Zo indication. The phase indication will usually be near zero when the impedance is at a minimum.3.01SORTING OUT MULTIPLE RESONANCE POINTSMost all transducers you test will have three major resonance points. A majorresonance point has a significant peak in the resonance indicator and a lowimpedance over a narrow frequency range. The problem is to determine thecorrect resonant point. This will usually be the frequency where the most power is transferred from the face of the transducer. Check the energy transfer at each resonant point by pressing on the exact center of the transducer face with afingertip while observing the impedance displayed on the top line of the LCD.The readings will change noticeably with moderate finger pressure. Theresonant point that produces the most pronounced change of impedance isusually, BUT NOT ALWAYS, the correct operating frequency for the transducer.3.02MEASURING TRANSDUCER IMPEDANCEThe transducer impedance at resonance is indicated on the upper left of theLCD. The relative phase angle is displayed in the upper right of the LCD. Anegative (-) sign indicates the load looks capacitive to the TT-2D, and apositive sign (+) indicates the load is inductive. The lowest impedance reading will usually occur when the relative phase angle displayed is less than ten.3.03TRANSDUCER DC RESISTANCEPress button ‘A’ to check the resistance of the transducer. The measurementrange is from 10 ohms to 5 megohms. Piezoelectric transducers that are nottransformer coupled should indicate “> 5 Megs” of leakage after a few seconds.Transformer coupled transducers usually have only a few ohms of resistance,and the LCD will indicate “<10 Ohms.”4HOW IT WORKSThe TT-2D sends a signal through a 100 ohm resistor to the transducer under test. The voltage waveform at the transducer is sampled at three specific points per cycle. The relationship of the voltages at the sample points determine the impedance and relative phase of the voltage across the transducer. The impedance is calculated and displayed over the range of 1 to 9990 ohms and the relative phase shift is displayed to the right of the impedance reading. A plus (+) sign (voltage leads current) indicates an inductive load, and a minus (-) sign (voltage lags current) indicates a capacitive load. The numbers following the polarity sign range from 0 to 30, with the higher numbers indicating a higher reactance.5CALIBRATIONCalibration of the TT-2D should not be necessary unless repairs have been made or internal parts have been changed. The calibration is done with the output short-circuited. The TT-2D is then checked with a 100 ohm and 1000 ohm resistor across the output to see if the displayed readings are within specifications. The equipment required to check the TT-2D calibration follows:5.00.01Frequency counter with .005% or better accuracy.5.00.02100 ohm 5% resistor.5.00.031000 ohm 5% resistor.5.01CHECKING SHORT CIRCUIT LOAD CALIBRATIONTurn the TT-2D on. Check the displayed battery voltage. It must be greaterthan 6.5 volts. If not, replace the battery. Set the frequency to 50 KHz and short the output by connecting the test cable clip-leads together. The impedanceshould read within +1 to -1. If the reading is not within this range the unit should be calibrated. See the SHORT CIRCUIT LOAD CALIBRATION procedure below for instructions.5.02CHECKING RESISTIVE LOAD CALIBRATIONTurn the TT-2D on and set the frequency to 50 KHz. Short the clip leads andverify that the reading is within +/- 1 ohm. If the reading is out of spec, try theSHORT CIRCUIT CALIBRATION procedure.5.02.01Connect the 100 ohm resistor to the clip leads and verify thedisplayed reading is 100 +/- 10 ohms. If the reading is notwithin specifications the unit must be returned to the factoryfor repair.5.02.02Remove the 100 ohm resistor and connect the 1000 ohmresistor. Verify that the displayed reading is 1000 +/- 100ohms. If the reading is not within specifications the unitmust be returned to the factory for repair.5.03CHECKING FREQUENCY ACCURACYSet the TT-2D as close as possible to 50 KHz. Connect the counter to theXDUCER jack and verify that the displayed reading is within 0.05% (+/- 0.025kHz at 50 Khz) of that on the frequency counter. If the reading is out of spec the unit must be returned to the factory for repair.5.04SHORT CIRCUIT LOAD CALIBRATIONTurn the TT-2D on and store frequency range 3 as the default. Set thefrequency to 50 Khz. Turn TT-2D off. Connect the clip leads together to shortcircuit the output. Press and hold both the ‘A’ and ‘B’ buttons and then turn onthe power. Watch the display and release both buttons immediately after thedisplay shows ‘Cal mode’. If the buttons are not released quickly, the unit willnot enter the calibration mode. Wait a few seconds after the display changes to “ADC=xxx” on the top line and then press button ‘B’ to store the ADC calibration value. Turn the TT-2D off then back on. Check to make sure the impedancereads within +/- 1 ohm. If not, check the test lead for continuity and repeat thecalibration. If the reading is still out of specification the unit must be returned to the factory for repair.5.05OHM METER CHECKTurn the TT-2D on and press button “A” to put the TT-2D into the DC resistance measurement mode. Short the clip leads together and verity that the display reads < 10 Ohms. Open the clip leads and verify the display reads > 5 M ohms. Place a 10 K resistor across the clip leads and verify the display reading is between 9000 and 11000 ohms. If the readings are out of specification the unit must be returned to the factory for repair.6BATTERY TESTThe battery should be replaced if the voltage falls below 6.5 volts as indicated on the display when the TT-2D is powered-up.6.01BATTERY REPLACEMENTThe battery compartment is located on the back side of the TT-2D. Turn the TT-2D face down and remove the battery cover by pressing down and outward with your thumb. The cover will then slide free from the case, exposing the battery.If possible, use 9V alkaline batteries for replacement.7SPECIFICATIONSFREQUENCY RANGE:.5 to 500 KHz, typically .1 to 550 KHZ.FREQUENCY ACCURACY:0.05% of indicated frequency +/- 1 digit.FREQUENCY RESOLUTION:0.01 KHzIMPEDANCE RANGE: 5 - 1000 ohm, usable 1 - 9990 ohms.IMPEDANCE ACCURACY:10% of indicated reading.TRANSDUCER TYPES:All types, including transformer coupled.BATTERY TYPE:Standard 9V transistor radio type.CURRENT DRAIN:20 mA avg, 60 mA max.EST BATTERY LIFE: 6 to 8 hours continuous use.RECOMMENDED BATTERY:Alkaline type similar to EVER READY #522or equivalent.WEIGHT:11 ounces with battery and test cable.SHIPPING WEIGHT: 2 pounds.8WARRANTY INFORMATIONUnit will be repaired free of charge for one year from date of purchase providing there is no water damage or other evidence of improper use or handling. Purchaser must ship unit prepaid to address below; EDI will pay the return freight. Please call before shipping your unit back to us.Phone:1-757-421-2968Fax:1-757-421-0518For repair ship to:Electronic Devices, Inc.3140 Bunch Walnuts RoadChesapeake, VA. 23322ATTN: Service DepartmentPlease enclose a note describing the problem.9COMMONLY ASKED QUESTIONS9.01HOW TO SET THE CONTRASTTo set the contrast, turn the TT-2D off and back on. Press button ‘A’ or ‘B’ while the battery voltage is displayed. The contrast setting is stored when theimpedance and frequency display appears approximately three seconds afterreleasing the buttons.9.02HOW TO CHANGE THE FREQUENCY RANGETo change the frequency range press button ‘B’. The range (1, 2, or 3) will bedisplayed while the button is held down. When the button is released the TT-2D will operate on that range.9.02.01The frequency range can be stored so it is selected whenever theTT-2D is turned on. To store the range select it as above, but donot release button ‘B’ when the range number is displayed. Whilethe range number is displayed, press button ‘A’ then release bothbuttons. The display will momentarily read “FR store” to indicatethe frequency range has been stored to memory.9.03HOW TO MEASURE LEAKAGEPress and release button ‘A’ and the display will read “Ohms chk” on the topline. The resistance will be displayed on the bottom line in exponential format.For example, a 1,200 ohm resistor will read “1.20E+03" on the bottom line of the display. If no leakage is present, the display will read “>5M ohms”. Allowseveral seconds to elapse for the reading to stabilize. To return to normaloperation, press and release button ‘B’.9.04HOW TO DETERMINE IF A TRANSDUCER IS DEFECTIVEA transducer is defective or the wiring is faulty if no resonant points areobserved. All transducers should have a strong indication of resonance at ornear the published operating frequency.9.04.01 A multi-element transducer with one damaged element mayresonate at the correct frequency, but the impedance reading willchange by a good amount. If there is any doubt, compare thereadings to a known good transducer. When making comparativereadings, both transducers must be tested in air or in water. Donot compare the reading in air to the reading in water as there willbe a big difference in the measured impedance.9.04.02If a transducer indicates any measurable leakage (less than 5Mohms), the wiring should be checked. If the wiring is not leaky, thetransducer should be replaced even if it is working ok on the depthsounder. Becuase of the high pulse voltage used, a leakytransducer will soon break down internally and cease to operate.。
使用RS232转换成422的数据线TT维修人员使用手册TT是奥的斯电梯的专用服务器，主要用于调试人员的现场调试操作，但如果维修人员能熟悉它，充分利用它，将能缩短故障排查时间，在相对短的时间内解决问题。
下面将以西奥21VF型号的电梯说明TT在此类电梯中的使用方法。
第一篇XO21VF概述XO21VF用了MECS，即模块化控制系统。
它由四个子系统组成，这些子系统包括操作控制子系统（OCSS）、运行指令子系统（LMCSS）、门控制子系统（DISS）、驱动控制子系统（DBSS）。
每个子系统（也叫服务系统）已经电脑化并能按设计好的要求完成专门的功能。
此外，每个服务系统靠串行传输线传送参数，交换信息。
第二篇OCSS操作子系统(即RCBII板子)一、概述。
OCSS是一个管理操作功能的服务系统，负责此系统的PC板是RCBII。
OCSS的功能是：负责指令、召唤、层楼显示、地震、消防运行目的层、开关门方向等的接受处理。
几乎所有的输入、输出信号（如：指令、召唤、层楼显示、停电自拯救、地震、消防、方向灯、蜂鸣器、厅外铃、停止开关等）都靠一个远站（RS5）与OCSS串行传输，此系统能靠一小组电线完成。
在OCSS和远站（RS）之间，考4根电线通讯，其中两根电源线（DC30V，HL2），两根信号线（L1，L2）。
OCSS有三组不同的串行信号线，分别是C/C（连接轿厢）、C/H（连接厅外）、G/H（连接群控）。
二、TT简介A、TT的前面板由一个显示屏和16个键组成，显示屏有两行。
B、激活键的蓝键功能：按SHIFT键（左下角没有标识的键），然后按相应的键。
比如，如果按下GO ON/GO BACK键，将会出现GO ON（往下翻页）功能，但是按住SHIFT键，然后按GO ON/GO BACK键，将会出现GO BACK（往上翻页）功能。
C、当按下SHIFT键后，显示屏的第一个字符那里将会有指针闪烁。
图一：TT按键排列示意图各按键的功能见下表：三、如何连接TTTT是连接在RCB上的P1端口，这样的连接可以进入OCSS和有限的进入MCSS，DBSS，DCSS。
T/T Telegraphic Transfer 电汇介绍电汇是汇出行应汇款人的申请，拍发加押电报或电传(Tested Cable/Telex)或者通过SWIFT给国外汇入行(也称解付行)，指示其解付一定金额给收款人的一种汇款结算方式。
电汇以电报、电传作为结算工具，安全迅速、费用也较高，由于电报电传的传递方向与资金的流向是相同的，因此电汇属于顺汇。
电汇是目前使用较多的一种汇款方式，其业务流程是：先由汇款人电汇申请书并交款付费给汇出行，在由汇出行拍加押电报或电传给汇入行，汇入行给收款人电汇通知书，收款人接到通知后去银行兑付，银行进行解付，解付完毕汇入行发出借记通知书给汇出行，同时汇出行给汇款人电汇回执。
电汇时，由汇款人填写汇款申请书，并在申请书中注明采用电汇T/T方式。
同时，将所汇款项及所需费用交汇出行，取得电汇回执。
汇出行接到汇款申请书后，为防止因申请书中出现的差错而耽误或引起汇出资金的意外损失，汇出行应仔细审核申请书，不清楚的地方与汇款人及时联系。
汇出行办理电汇时，根据汇款申请书内容以电报或电传向汇入行发出解付指示。
电文内容主要有：汇款金额及币种、收款人名称、地址或帐号、汇款人名称、地址、附言、头寸拨付办法、汇出行名称或SWIFT地址等。
为了使汇入行证实电文内容确实是由汇出行发出的，汇出行在正文前要加列双方银行所约定使用的密押(Testkey)。
汇入行收到电报或电传后，即核对密押是不是相符，若不符，应立即拟电文向汇出行查询。
若相符，即缮制电汇通知书，通知收款人取款。
收款人持通知书一式两联向汇入行取款，并在收款人收据上签章后，汇入行即凭以解付汇款。
实务中，如果收款人在汇入行开有帐户，汇入行往往不缮制汇款通知书，仅凭电文将款项收入收款人收户，然后给收款人一收帐通知单，也不需要收款人签具收据。
最后，汇入行将付讫借记通知书(Debit Advice)寄给汇出行。
电汇中的电报费用由汇款人承担，银行对电汇业务一般均当天处理，不占用邮递过程的汇款资金，所以，对于金额较大的汇款或通过SWIFT或银行间的汇划，多采用电汇方式。
