Multifunction Calibrator CA71 (Portable)

Multifunction Calibrator CA71 (Portable)

The CA71 Portable Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals. The Handy Calibrator incorporates rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you're ready to take measurements.

Multifunction Calibrator CA71 (Portable)

Product Overview:
A Wide Array of Useful Functions：
·Source
·Values set in steps of 4-20 mA 24V DC Power Supply to Transmitter
·Divided output (n/m) function
·Output settings are divided, eliminating the need for bothersome calculations for percentage output.
·Autostep function
·Changes the output value in step form based on the setting from the divided output (n/m) function. Changes can be sourced automatically every 10% or 25%.
·Online communication (CA71 only) RS-232C-compliant optically isolated interface
·Sweep function
Linearly increases or decrease the output. The increasing/decreasing time can be set to either 16 or 32 seconds.
·Memory function
Source values and measurements forming individual value sets can be saved to or read from the Handy Calibrator's internal memory (maximum 50 value sets).
·Temperature monitor function
