The CA71 Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals. The Calibrator incorporates rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you're ready to take measurements. A wide array of useful functions are offered. Including: Source (output can be set in steps: Power Transmitter Divided (n/M, eliminating need for calculations for percentage output) Autostep (changes can be sourced every 10% or 25%) online communication (RS-232) Sweep (linearly changes output over 16 or 32 seconds) Memory (50 sets) and Temperature Monitor function.
