Lighten your load by taking the TechChek to everysite. It’s like bringing a cartload of test equipment fromthe shop to the control room or the field. The TechChek820 sources & reads DC like a milliamp or voltagecalibrator, simulates and measures T/Cs & RTDs like atemperature calibrator and generates and countsfrequency & Counts-Per-Minute like a frequency calibrator. Troubleshooting? It checks continuity and measuresAC line voltage like a multimeter!
The TechChek 820 is easy to use. Select a function,choose a range, and turn the knob for the precise outputyou need. Plus, you can store three output values perrange for instant recall with the “QUIK-CHEK” switch.
MILLIAMP CALIBRATION
Use at every point in your 4 to 20 mA loop. You canSource & Read 0.00 to 24.00 mA, Simulate a Two-WireTransmitter or the use the TechChek 820 to simultaneously Power & Measure your Two-Wire Transmitters.
VOLTAGE CALIBRATION
Calibrate all your DC millivolt and voltage instrumentation. Source from 0.00 to 110.00 mV and 0.00 to 10.25 V.Read up to 110.00 mV, 11.00 V and 200.0 VDC.
THERMOCOUPLE CALIBRATION
Source and read directly in °C and °F for T/C typesJ, K, T & E with 1° resolution. Cold junction compensation automatically adjusts for ambient temperaturechanges.
RTD CALIBRATION
Built-in Platinum 100 Ohm DIN/IEC 751 tabledisplays in °C or °F. No more decade box and hard-toread tables. Also reads and sources in Ohms.
FREQUENCY CALIBRATION
Generate Zero Crossing square waves from 1 to1000 Hz, 0.01 to 10.00 kHz and from 1 to 1000 CPM(Counts-Per-Minute). Also measures as a frequencycounter.
MEASURE AC VOLTAGE
Check your line voltage or mains from 0.0 to 250.0volts AC. Great for troubleshooting power problems.
CHECK CONTINUITY
Locate pairs of wire, open connections and shortswith the built-in beeper.
