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
w.
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
e while the
EZ-CHECK™ switch
q is in the “HI”, “LO” or “SET”
position. Press and turn the knob for faster dialing
with 10° (or 0.100) increments.

STORING HI and LO EZ-CHECK 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 EZ-CHECK switch to the HI position
and turn the
e EZ-Dial knob until the desired temperature is on the display. Press and hold the
EZ-Dial knob until STORED appears to store the value. Release the EZ-Dial knob.
2) Store your low (ZERO) output temperature by moving the EZ-CHECK switch to the LO position
and turn the
e EZ-Dial knob until the desired temperature is on the display. Press and hold the
EZ-Dial knob until STORED appears to store the value. Release the EZ-Dial knob.
3) Instantly output your SPAN and ZERO temperature outputs by moving the EZ-CHECK switch
between HI and LO. You may also select any third temperature output (such as mid-range) using
the SET position on the EZ-CHECK switch.
