NewGen Instruments and Surgicals - Calibrating Machine

The CA71 Portable Calibrator is a small, lightweight, multifunction calibrator by Yokogawa that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals with high accuracy. 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.

General Yokogawa CA71 Specifications:

• Divided output (n/m) function, Auto-step function, Sweep function, Memory function and Communication function
• Generate voltage/current up to 30 V DC/24 mA DC and measure up to 100 V DC/100 mA DC
• Can be used as a multi thermometer
• Built-in reference junction compensation sensor
• Frequency can be set in the range of 1 Hz to 11 kHz
• Source and measure operations can be performed at the same time. (Select from the following source signal and measurement signal options: voltage, current, resistance, thermocouple (TC), resistance temperature detector (RTD), frequency, pulse).
• AC voltages, including supply voltage, can be measured.
• Includes a wide array of additional functions.
• Easy operation.
• Compact size and Lightweight

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
