Features

Voltage/Current Calibrator

Source and Measuring of Voltage and
Current

Generates and measures voltages up to 30 V DC and
currents up to 24 mA DC.

Improved display resolution

for current

The generation/measurement resolution
has improved to 0.001 mA.

24 V (20 mA)/Loop check
function*

Enables measurement of generated
current signals while supplying loop
power to two-wire transmitter.

* Load current: Max. DC22 mA

20 mA SINK Function

Absorbs the voltage supplied from an external power
supply to its H terminal and simulates a two-wire
transmitter making it ideal for loop checks.

4-20 mA and 1-5 V DC Step-up/
down Function

The output level can be changed between 4 8 12
16 20 mA signals by one touch for the 4-20 mA DC
output, and between 1 2 3 4 5V signals for the
1-5 V DC output, for efficient calibration work.

Sweep Function

Increases and decreases the output level to the preset
level at a constant rate for the selected sweep time (16
or 32 seconds). The sweep function and sweep time
are set by the internal dip switches.

Panel Design Common to All Models

Power Switch

Up/Down Keys

Used to set the output signal level. A pair of up/down
keys is conveniently located immediately below each
digit in the LCD panel.

Output On/Off Switch

(Output signal can set ON/OFF)

Range Selection Rotary Switch

The rotary switch simplifies range selection: just leave
the switch set to the most frequently used range.
