Model PCS-2/B
current-to-voltage calibrator or transconductance amplifier

GENERAL DESCRIPTION
The Model PCS-2/B is a current-to-voltage calibrator or transconductance amplifier. The current output is directly proportional to the input voltages from a high accuracy AC or DC voltage standard. The input voltage to the unit can be AC or DC up to 1kHz.  The ratios of 10 volts to output is: 1:1, 1:0.1, 1:0.01, 1:0.001 and 1:0.0001.  The PCS-2/B is laboratory calibrated with instruments and load resistors traceable to N.I.S.T. (National Institute of Standards & Technology).  The unit is also equipped for rack mounting in a standard 19" rack.

Recommended for DC Models 511 and 521

The PCS-2B may also be used with AC and DC voltage sources (calibrators) of other manufacturers.

APPLICATIONS
Applications for the Model PCS-2B include: Direct Calibration of Watt Meters, Meter Shunts, AC and DC Current Meters, I to E Transducers, DVMs, DMMs, Relay Coil Current Testing.
