The Martel Electronics PSC-4000 Process
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-4000 incorporates multiple input/
output ranges for both current and voltage
operating modes. When operated in the current
mode, the calibrator can source, simulate, or
read over a 0 to 24 mA range, with 0.01 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-4000 can read or source over
two ranges, 0 to 20.00 V, or 0 to 200.0 mV.
