HA2500Patented “Ringer” Proves TheCondition Of Flybacks, Yokes,And Coils In SecondsThe Ringer Test is used to isolate a shorted turnwithin flybacks, yokes, or coils when the Load Testindicates a horizontal output stage defect. A shortedturn or turns greatly alters the component’s functionand circuit’s operation, but does not changethe winding’s resistance or its inductance when youmeasure it.The HA2500 RingerTest quickly confirmsa shorted turn defectsaving you fromreplacing a goodflyback, yoke,or horizontal coil; orworst yet, mistakenlyconcluding it’s defective and losing the repairand revenue opportunity.The Ringer Test may be used effectively to isolateshorted turns among other coils and transformersabundant in today’s multi-frequency CRT displays.Coils in the B+ voltage path commonly developshorted turns when a horizontal output stage defectproduces high current through them. The RingerTest quickly identifies when these coils have beendamaged and need to be replaced.Call 1-800-SENCORE, Today!(736-2673)6 SENCORE

Dynamic Tests Analyze TheHorizontal Output Stage WithAutomatic MeasurementsThe HA2500's Dynamic Tests “METER” providesautomatic measurementsof voltages and waveformsto quickly analyze the horizontal output stage withoutcomplicated setup, probing multiple circuitpoints, selecting multiple test functions, or worry oftest equipment damage.Measurements confirm normal or abnormalhorizontal output stage operation and guide youto suspect stages or defects in either bipolar orMOSFET type horizontal output transistor stages.The Collector Or Drain Meter provides threeautomatic “chassis on” measurements of voltagesand waveforms produced by the horizontal outputstage at the collector or drain of the horizontaloutput transistor. These measurements include theDC voltage, the flyback pulse peak-to-peak voltage,and the flyback pulse duration or time in microseconds.The BASE OR GATE Meter provides two automaticmeasurements of the drive waveform at the base orgate of the horizontal output transistor.SENCORE 7

HA2500Exclusive Horiz. Driver TestDetects Weak Or IntermittentHorizontal Base DriveHorizontal output stage symptoms and componentfailures are often caused by defects in the horizontaldrive stage. Yet, the driver stage is seldomsuspected and often when it does have a defect,scope waveforms and peak-to-peak measurementsat the base of the horizontal output transistorappear normal.Horizontal driver stage defects and symptoms aredifficult to diagnose for several reasons.1. The symptoms are the same as horizontaloutput stage defects.2. Horizontal output transistors may burn-outquickly leaving no time for measurements.3. Horizontal output transistors may run hotterthan normal and burn-out after several minutes,hours, or days while waveforms and horizontaloutput stage functions appear normal.The HA2500'sHoriz. Driver Testis an exclusiveanalyzing testdesigned to identifyhorizontaldriver stagedefects. TheHoriz. Driver Testanalyzes horizontaldriver stagesthat produce basedrive for bipolarhorizontal output transistors. The test identifies horizontaldriver stages which are not producing anadequate current drive for proper operation of abipolar type horizontal output transistor.By isolating horizontal driver stage defects with theHA2500, you prevent wasted time troubleshootingthe horizontal output stage, save money replacingrepeat horizontal output transistor failures andmake revenue from monitors with inexpensive drivestage problems you may have missed before.10Call l-800-SENCORE, Today !(736-2673)S E N C O R E

HA2500H.O.T. Base Or Gate SubDrive Enables HorizontalOutput Stage AnalyzingHorizontal drive defects can cause the horizontaloutput stage to be dead or appear defective.Symptoms include missing or reduced highvoltage and/or deflection, audible noises, pictureinterference, and reduced HV or deflection. Theonly way to determine if the problem is caused by ahorizontal drive signal defect or more expensivedefects in the horizontal output stage is to accuratelysubstitute the horizontal drive at the base or gateof the horizontal output transistor.The Base Sub Drive outputs the proper horizontaldrive for the base of any bipolar type horizontaloutput transistor.The drive currentis dynamicallyadjusted toproduce theneeded horizontaloutput transistor collector current and besttransistor switching efficiency. This enables theBase Sub Drive to drive any horizontal outputbipolar transistor without excessive heatingand/or transistor damage. The Gate Sub Driveoutputs the proper horizontal drive for the gateof any MOSFET type horizontal output transistor.When "Drive" is selected, the fluorescent displayshows the HA2500's horizontal test frequency andthe DCV at the chassis horizontal output transistorcollector or drain. Pressing the Horiz. Driver TestOr Sub Drive push-button outputs drive to the chassishorizontal output transistor and is accompaniedby Collector Or Drain measurements to analyze theoperation of the horizontal output stage.By substituting for missing or suspected badhorizontal drive, the HA2500 enables testing ofexpensive horizontal output stage components andpower supply stages. It further helps isolate weak,intermittent, erratic, or noisy horizontal drive signalproblems which cause improper horizontal outputstage operation and/or results in output transistorfailure.S E N C O R E11

Substitute B+ Power SupplyIsolates HV Breakdown,Shutdown, & HV/DeflectionDefectsThe HA2500's Substitute B+ Supply substitutes forthe chassis B+ power supply voltage. It enablesyou to power the horizontal output stage to fullpotential when the B+ supply or high voltage deflectionregulator has damaged components.It lets you slowly increase the B+ voltage andlimit the current to isolate horizontal componentbreakdown failures and X-ray shutdown symptoms.It provides an effective method of isolatingB+ voltage defects to the B+ supply, HV/deflectionregulator; or horizontal output stage.The Substitute B+ Supply is variable from 30 - 180volts to match a wide range of B+ voltages found infull sized CRT video displays. The voltage is switchedoff or adjusted through its range with the VOLTScontrol. The maximum outputpower of the Substitute B+Supply is adjustable from
