The Martel PSC-9003 is a full function process signal calibrator capable of sourcing and reading all common process signals such as volts, millivolts, milliamps and frequency. This wide range of capability makes the PSC-9003 ideal for calibrating or monitoring trans-mitters, recorders, flow instrumentation, data acquisition equipment or any other process instruments requiring these types of signal inputs.

Housed in a rugged hand-held case, the PSC-9003 features 0.05% basic accuracy on all ranges. Up to nine (9) calibration setpoints can be stored in non-volatile memory for each of the ranges. An auto-step function allows the user to automatically step through each of the stored setpoints for a particular range at a predetermined interval.

An internal 24 volt loop power sup-ply allows the unit to power two-wire transmitters while reading the current loop. As a simulator, the PSC-9003 can drive current loops up to 1000 ohms and can source up to ±1 mA when operated in the voltage mode.

Each Unit Includes: Test leads, large carrying case, 4 AA alkaline batteries, NIST Certificate, and instruction manual.
