1. FEATURES
* Portable instrument for calibrating process devices andmeasuring process signals.
* Adjustable 0-24 mA current source.* Adjustable -199.9 mV to +199.9 mV DCV source.* Current calibrator drives loads up to 500 ohms.* The instruments can power as well as measure a two-wirecurrent loop, useful for testing 4-20mA loop devices ( forexample pressure transmitters).
* Four functions include: 1) Precision current source2) Measurement of current signal 3) Simultaneous poweringand measurement of a 2-wire current loop 4)Precision DCmV source
Function
1) Current source : Range & 2 ranges : Resolution 0 - 19.99 mA x 0.01 mA 0 - 24 mA x 0.1 mA
