 Calibrate electronic process instruments
such as controllers, transmitters, or recorders with the model
CAL30 Process Calibrator. Model CAL30 is designed to independently
measure and simulate DC volts, mV, and current. These calibrators
simulate a two-wire field transmitter and generate a controlled
output current when connected to an external power supply. Units
source is a four-wire transmitter by generating a controlled
4-20 mA DC from an external 25 V power supply.
Programmable functions, such as square root extraction for flow
signals, ramp/step increment value, selectable engineering units,
isolated signal conversion, or automatic changing of the output
value simplify many calibration tasks. Calibration values can
be stored and recalled using the Low, Mid, or High keys. Program
the automatic shut-off to conserve battery life.
The Model CAL30 Calibrator features 500 VDC input/output isolation
and reverse polarity protection. The unit includes three 9V batteries,
two sets of dual test leads, a dual binding post adapter, carrying
case, and instruction manual.
