Calibrators

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
andmeasure 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 source and
measurement capability
The CA71 lets you handle regular tests on TCs, RTDs and various
other types of sensors and instruments, aswell as operation
checks when a problem has occurred. By itself it can source
signals for input to equipment, and check output signal from
equipment. With the CA71, you don't need to worry about
synchronizing operations with other setting devices.
(TC and RTD measurement functions are CA71 only.)

A wide array of useful functions
Source
Values set in steps of 4-20 mA
24V DC Power Supplyto 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 isolatedinterface
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

Easy operation

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. There is no need for a
separate multimeter to measure supply voltage.

The Handy Calibrator incorporates rotary switches for simplehandling. Just open the carrying case cover and connect the
cables, and you're ready to take measurements.
