Comprehensive source/measure instruments for all your calibration and equipment checking needs at maintenance sites.
Sensors and instruments require a wide variety of operation checks in the field.
The CA71 Handy Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals.
The CA51 Handy Calibrator is a basic model with the same functions as the CA71 except TC and RTD measurement functions and online communication functions.
Simultaneous signal generation and measurement capability:
The CA71 lets you handle regular tests on TCs, RTDs and various other types of sensors and instruments, as well as operation checks when a problem has occurred (TC and RTD measurement functions are CA71 only.)
AC voltage (including supply voltage) measurement capability:
In cases where numerous signal converters and other devices are mounted on a rack or panel, the Handy Calibrator can be used to check the input and output signals of each device, while simultaneously checking the power supply.
A wide array of useful functions:
Source: Values set in steps of 4-20 mA, 24V DC Power supply to transmitter
Online communication (CA71 only):
RS-232C-compliant optically isolated interface
Divided output (n/m) function:
Output settings are divided (n/m), eliminating the need for bothersome calculations for percentage output
Auto step function:
Changes the output value in step form based on the setting from the divided output (n/m) functions. Changes can be generated automatically every 10% or 25%
Sweep functions: Linearly raises or lowers the output. The raising/lowering time can be set to either 16 or 32 seconds
Source values and measurements forming individual value sets can be saved to or loaded from the Handy Calibrator's internal memory (maximum 50 value sets)
The Handy Calibrator incorporates rotary switches for simple handing. Just open the carrying case cover and connect the cables, and you're ready to take measurements
