Clamp-On Tester

TPI Clamp-On Tester 275 with True RMS Digital Multimeter and 11000 Count DisplayIncludesCarrying PouchTest Lead SetTemperature ProbeInstruction ManualBattery & FuseThe slim design 275 is a hand-held, autoranging clamp-on DMM. Extra large numerals, min/max, capacitance, DC microamps and duty cycle are just a few of the features of the 275. An affordable choice, the 275 offers measurements in all basic electrical functions with additional advanced features like non-contact voltage.Perform the following tests and/or measurements with the 275 and the appropriate function:HVAC/RDCmV Thermocouples in furnacesACA Heat anticipator current in thermostatsACV Line voltageACV or DCV Control circuit voltageOHMS Compressor winding resistanceOHMS Continuity of wiringCAP Motor start and run capacitorsACA Motor and compressor start up currentHz Frequency on controls and line voltageTEMP Air duct temperaturesALL Bar graph to indicate rapid fluctuationsELECTRICALACV Measure line voltageACA Measure line currenOHMS Continuity of circuit breakersDCV Voltage of direct drive DC motorsACA Start up current of motors, relays, contactors and transformersELECTRONICACV Measure power supply voltageACA Measure power supply currentOHMS Continuity of circuit breakers and fusesModel 275 ApplicationsMeasure flame safety control currentTest start and run capacitors and motorsMeasure motor run current and capture peak motor start up amperageMeasure heat anticipator currentDetermine thermocouple voltageTest line and control voltagesMeasure heating element resistanceMeasure air temperature in ductsTest for the presence of voltage in circuits without contacting the circuitMeasure temperature differential using relative mode.
