Operation
Connecting thermocouples
1. This meter accepts two type K thermocouples with spade plugs (sub-miniature type
with one spade wider than the other).
2. Plug the thermocouple(s) into the meter's T1 and/or T2 thermocouple input jack(s).
Turn Power ON
1. Press the button to turn power on. The meter will perform a short self-test.
2. If a probe is not inserted to the meter, an “OL” indication will appear on the display.
Selecting °C, °F or °K units of measure
Press the C/F/K button to select the desired temperature unit of measure.
Selecting T1, T2, and T1-T2 Displays
Press the T1 T2 T1-T2 button to step through and select a display of:
a. T1 (thermocouple 1) displays in the upper large display and T2 (thermocouple 2)
temp. displays in the lower small display.
b. T1 plus T2
c. T1-T2 plus T1
d. T1-T2 plus T2
MIN, MAX, AVG Recording Function with Timer
Press the MX/MN button to begin capturing the Minimum (MN), Maximum (MX), and
Average (AVG) temperature values. The Elapsed Time clock will appear on the lower left
of the display and the lower display will indicate the MAXIMUM (MX) value captured since
the MX/MN button was pressed.
Press the MX/MN button to change the lower display to reflect the stored MX to MN and
then AVG value of the input selected in the upper display (T1, T2 or T1-T2). Each reading
will be accompanied by a Timer value indicating the time when each reading was
recorded.
Press the Time button to change the elapsed time format from min:sec to hour:min.
Press and Hold the MX/MN button until the display returns to standard operation to exit the
MX/MN function.

Data Hold
Press the HOLD button to freeze the reading in the display. The 'H' hold icon will appear
on the upper left-hand side of the display. Press the HOLD button again to return to normal
operation (the 'H' hold icon will disappear).
Offset
The Offset Mode permits the user to store the temperature reading as a reference value
and compare this reference value to subsequent temperature readings. In Offset mode, the
meter displays the actual measured temperature minus the stored reference value.
Press the OFFSET button to store the currently displayed temperature readings and enter
the Offset mode. “OFFSET” will appear in the display.
Press the OFFSET button to exit the mode.
