SOURCE
Choose this function to provide a simulated thermocouple signal into controllers, temperature
transmitters, indicators or any input devices that measure thermocouple sensors..
1) Disconnect the thermocouple sensor from the
device to be calibrated.
2) Select “
SOURCE
” with slide switch
.
3) Connect a thermocouple wire (matching the type
of wire to sensor being simulated) with miniature
male T/C connector to the inputs of the device
being calibrated, making sure to check polarity.
Millivolt outputs (without cold junction) may be
connected with a copper (white) miniature T/C
connector or the banana jacks with copper wire.
The output is adjusted in 0.1° (or 0.001 mV)
increments by turning the knob
while the
DIAL switch
is in the “HI”, “LO” or “SET”
position. Press and turn the knob for faster dialing
with 10° (or 0.100) increments.

Storing DIAL Outputs
STORING HI and LO DIAL Outputs
Choose this function to provide a simulated thermocouple signal into controllers, temperature
transmitters, indicators or any other input device that measure thermocouple sensors.
1) Store your high (SPAN) output temperature by moving the DIAL switch to the
HI
position
and turn the DIAL knob until the desired temperature is on the display. Press and hold the
DIAL knob until
STORED
appears to store the value. Release the DIAL knob.
2) Store your low (ZERO) output temperature by moving the DIAL switch to the
LO
position
and turn the
DIAL knob until the desired temperature is on the display. Press and hold the
DIAL knob until
STORED
appears to store the value. Release the DIAL knob.
3) Instantly output your SPAN and ZERO temperature outputs by moving the DIAL switch
between HI and LO. You may also select any third temperature output (such as mid-range) using
the SET position on the DIAL switch.
