Product Profile of Portable Process Calibrator

Microtek instruments is the manufacturer of the portable process calibrator, the martel electronics psc-4000. It is a portable, hand-held, full function voltage and current calibrator with the capability to both read and simulate common process control signals. The device incorporates multiple input and output ranges for both current and voltage operating modes. The salient features of the portable process calibrator:

• 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 percent 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.

• Up to three calibration points can be stored in memory for each voltage or current range. These calibration points are non-volatile, and will remain in memory until the user changes them
