CALIBRATE VOLTAGE INPUTS
V, mV
Choose this function to provide an output from 0.00 mV to 110.00
mV and from 0.00 to 10.25 VDC. Current compliance up to 20 mA
to provide the driving power to your voltage receivers.
1) Disconnect one or both input wires from the device to be
calibrated
2) Press the MILLIAMP/V push-button until V or mV appear on
the display
3) Press the DISPLAY/SOURCE/READ push-button until SOURCE
and V or mV appear on the display
4) Press the TYPE/ENG UNITS push-button once to switch
between V and mV on the display
5) Connect the red SOURCE lead of the calibrator to the plus (+)
input of the device and the black SOURCE lead to the minus (-).
Output voltage is continuously adjustable with the UP/DOWN
push-buttons. Zero & Span (or any other values) are available by
using the LO and HI "QUIK-CHEKs".

OPERATING INSTRUCTIONS
SIMULATE 2-WIRE TRANSMITTERS
2-WIRE mA, 2-WIRE % (Percent of 4 to 20 mA) 2-WIRE DP %
Choose this function to simulate a 2-Wire Transmitter output from
1.00 to 24.00 milliamps. Operates in loops with power supply
voltages from 3 to 45 VDC.
1) Disconnect existing 2-Wire Transmitter from the loop
2) Press the MILLIAMP/V push-button until mA or mA and %
appear on the display
3) Press the DISPLAY/SOURCE/READ push-button until SOURCE
or 2-WIRE appear on the display
4) If SOURCE is on the display, press the TYPE/ENG UNITS push-
button once to indicate 2-WIRE on the display
5) Press the mA/%/% DP FLOW push-button to display mA, % 4-20
or % DP Flow.
6) Connect the red SOURCE lead of the calibrator to the plus (+)
input of the device and the black SOURCE lead to the minus (-).
The simulated output of the 2-Wire Transmitter is continuously
adjustable from 1.00 to 24.00 mA with the UP/DOWN push-
buttons. Zero & Span (or any other values) are available by using
the LO and HI "QUIK-CHEKs".
