4 - 20 Ma-Loop Calibrator  >   MARTEL PSC-420

Current Calibrator

The PSC-420 is a full function, microprocessor based, 4 to 20
mA current calibrator that provides every feature required to
completely calibrate or diagnose a current loop.

The PSC-420 is a full function, microprocessor based, 4 to 20
mA current calibrator that provides every feature required to
completely calibrate or diagnose a current loop.

Up/down scroll control and three user defined setpoints
allow quick output changes. A percent/mA key offers the
option of reading directly in milliamps or percent of range. An
autostep key allows the three stored setpoints to be
toggled through with a user defined dwell time selectable
from 5 to 60 seconds, allowing "hands free" calibration.

The PSC-420 has full circuit protection and is powered from
either a 9 volt alkaline or Ni-Cd battery, or AC adapter.

Each Unit Includes:
Test leads, carrying case, 9V battery, NIST Certificate, and
instruction manual
