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.

UNITS

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

T1-T2

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

T1-T2

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.
