6. AUTO POWER OFF MODE
The thermometer enters sleep mode (default). That is to say, the meter will
automatically shut off after 20 minutes if no button press occurs for 20 minutes.
When the thermometer is in Setup mode, the display shows SETUP. Press or
to scroll to the"SLP" page . Press to indicate "ON"or"OFF". Press or until
the setting you want to use appears on the display (fig.2). Press to store the
new setting in memory. ON (sleep mode on) or OFF (sleep mode off).
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.
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 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.
