|Calibrate electronic process instruments such
as controllers, transmitters, transducers or recorders with the
model CAL20 RTD Calibrator. Model CAL20 is designed to independently
measure and Simulate and common RTD signals (100Ω Pt, 120Ω Ni,
10Ω Cu),ohms or measure current. Input/output can be operated
simultaneously with independent range selection.
A multitude of programmable functions, 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 CAL20 Calibrator features 500 VDC input/output isolation and reverse
polarity protection. View input and output values on the 24- character LCD.
The unit includes three 9V batteries, two sets of dual test leads, a dual binding
post adapter, carrying case, and instruction manual.
