1. Introduction

The Martel PSC4010 Multifunction Process Calibrator is a handheld, battery-operated
instrument that measures and sources electrical and physical parameters. The calibrator has
the following features and functions:

• A graphics display. The display can be used to source and measure volts, current,

frequency, and to source pulse trains.

• Setpoints in each range for quickly increasing/decreasing output

• An interactive menu

• Complete serial interface for remote control
