Additel ADT220 Loop Calibrator, Multifunction mA/mV/V
Additel ADT220 Loop Calibrator
Overview
The Additel ADT220 Loop Calibrator is a highly integrated multifunction loop calibrator featuring several patented technologies. In one rugged hand-held package it measures and sources loop current, mV and V, performs loop continuity tests, captures switch values and provides a 24 V loop power supply with simultaneous current measurement.
A smart-phone-like menu makes single-hand operation straightforward, while data statistics display max, min, peak-to-peak, average and percentage simultaneously. The ADT220 stores up to twenty thousand logged records, supports re-scaling to physical values, and passes a 1-meter drop test, making it a dependable field tool for calibrating and troubleshooting loop devices.
