Process Signal Calibrator

The PSC-4010 Process Signal Calibrator is a portable, hand-held, full function voltage and
current calibrator with the capability to both read and simulate common process control signals.
The PSC-4010 process calibrator incorporates multiple input/output ranges for both current
and voltage operating mode. When operated in the current mode, the calibrator can source, simulate,
or read over a 0 to 24 mA range with .01 mA resolution.
It can also supply 24 VDC to power a two wire transmitter while simultaneously reading back its output
both in milliamps or % of full scale. When operated in the voltage range, the PSC-4010 process signal
can read or source over two ranges, 0 to 20.00 volts or 0 to 200.0 mV.

PSC-4010 Process Signal Calibrator

Model  Description 
PSC-4010  Process Signal Calibrator includes Test Leads,
Protective rubber boot, Instruction Manual, NIST Calibration Certificate 

Reads and Simulates Process Control Signals
Memory for 3 Calibration Points in Each Range
Multiple Input / Output Ranges for Current and Voltage Mode
Built-in 24VDC Source for Powering Two-wire Transmitters
Accuracy of .025% FS± 1 LSD
