Dwyer Model CAL20 RTD Calibrator

Measures and Simulates Common RTDs, Programmable.
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.
