Tests/ calibrates instruments operating on 4-20 mA DC signal

High accuracy : 0.1% FSD - Bench top accuracy in a Tool Box Calibrator

Multifunction capability: Sources 4-20 mA; Reads 0-20 mA; Simulates 2-wireTransmitter and powers 2 Wire Transmitter and measures its mA output in the range 4-20 mA

Instant check of 4 mA & 20 mA end points; and also fast check of any intermediate point in both Source & 2-wire Transmitter simulate mode

Circuit design ensures stability of set current regardless of changes in voltage and load

Large clear 3½ digit LCD, 0.5" high

Portable, rugged and dry cell powered - Ideal for use in field & control room
