PCL120
1. Introduction
The OMEGA PCL120 is designed to be a complete 4 to 20mA current
calibrator for both trouble-shooting and calibrating current loops. Very
high accuracy combined with several unique features makes the PCL120
an easy to use and highly
calibration tool.
The PCL120 can source, simulate (2-wire) or measure loop currents up to
24mA. It can also measure process signal voltages up to 28VDC with the
same 0.015% of reading accuracy. A digital knob user interface combined
with decade output control allows the user to make both large or small
output changes with ease. Several unique functions such as the auto-
step/ramp modes allow the PCL120 to test valve actuators for smoothness
and proper operation.
The PCL120 can also power two-wire transmitters while simultaneously
reading the resultant loop current. All readings are displayed in both
milliamps and % of span.
