[PIE] LOOP CALIBRATOR PIECAL 434

Automated 4-20mA Loop Calibrator with Loop Diagnostics


제품특징

Calibrate Milliamp Instruments: Source 0.000 to 24.000 mA & -25.00 to 125.00% of 4-20 mA Read 0.000 to 24.000 mA & -25.00 to 125.00% of 4-20 mA Read -99.99 to 99.99 V Simulate 2-Wire Transmitter, Power & Read Transmitters Menu Selectable 250 Ohm resistor for HART compatibility


Calibrate with Lab Accuracy: Accurate to ±(0.01% of Reading + 0.002 mA) PIECAL 434 is more accurate than similar calibrators - within ±0.004 mA at 20 mA output!


Easy-to-Read Backlit Display


Locate Loop Current Leakages: Automatic indication of Loop Current and Leakage Current. Measure ground current leakage from faulty wiring, flooded conduit and corrosion bridges. Leakage typically appears as a Zero Shift and helps you decide if the transmitter needs calibration or if there is a problem in the loop wiring.


Faster Calibrations: Three output EZ-CHECK switch 2 speed EZ-DIAL Stepping & Ramping

Includes Rubber Boot, Test Leads and hands free carrying case
