7. MEASURING TEMPERATURES
7.1. CONNECTING A THERMOCOUPLE
To change the thermocouple type, see “Changing Setup Options."
The North American ANSI Color Code is:
1. Plug a thermocouple into the input connector(s). (Make sure that the
polarity is correct.)
2. Set the thermometer for the correct thermocouple type.
7.2. DISPLAYING TEMPERATURES
1. Press to select the correct temperature scale.
2. Hold or attach the thermocouple(s) to the measurement location. The
temperature reading appears in the primary display.
3. Press to toggle between showing the T1, T2, , and T1-T2 readings in
the primary or secondary display.
Notes: The display shows "- - - -" when a thermocouple is not connected.
The display shows OL (overload) when the temperature being measured is
outside the thermocouple's valid range.
7.3. HOLDING THE DISPLAYED READINGS
1. Press to freeze the readings on the display. The display shows HOLD.
2. Press to toggle showing the T1, T2, or T1-T2 readings in the primary or
secondary display.
3. Press again to turn off the HOLD function.
7.4. VIEWING THE MIN, MAX, AND AVG READINGS
1. Press to step through the maximum (MAX), minimum (MIN), or the
average (AVG) readings. The elapsed time since entering MIN MAX mode,
or the time at which the minimum or maximum occurred appears on the
display.
2. Press button for 3 seconds to exit MAX, MIN and AVG mode.
7.5. USING THE OFFSET TO ADJUST FOR PROBE ERRORS
Use the offset option in Setup to adjust the thermometer's readings to
compensate for the errors of a specific the thermocouple and IR temperature.
The allowable adjustment range is ± 5.0°C or ± 9.0°F.
1. Plug the thermocouple into the input connector.
2. Place the thermocouple in a known, stable temperature environment (such
as an ice dry well calibrator).
3. Allow the readings to stabilize.
4. In Setup change the offset until the primary reading matches the
calibration temperature. ("Changing Setup Options.")
7.6. REPLACING THE BATTERIES
1. Turn off the thermometer if necessary.
2. Loosen the screw and remove the battery door.
3. Replace 1.5V batteries.
4. Replace the battery door and tighten the screw.
