Operation

Connecting thermocouples

1. This meter accepts a K/J-type thermocouple with spade lugs (sub­miniature type with one spade wider than the other).

2. Plug the thermocouple into the meter's thermocouple input jack.

Measuring

1. Press the button to switch ON the thermometer on. After 1
second the thermometer will display the first temperature reading
(upper display).

2. Press the C-F-K button to select the desired temperature unit of

MAX/MIN/AVG mode

measure. A display icon will reflect the selection.

3. Touch the object to be measured with the probe. Read the
measured temperature on the display.

Note: If the display indicates “OL” the temperature is outside the
measurement range. The display shows "- - - -" when a
thermocouple is not connected.

Press MAX/MIN to capture and step through the maximum (MAX),
minimum (MIN) and average (AVG) temperature values. These values will
be shown in the lower display with an elapsed time reference below
(hrs:mins, mins:secs).

1. Press MAX/MIN to enter this mode.

2. Press MAX/MIN to step through maximum, minimum and average
readings.

3. Press and hold MAX/MIN for 3 seconds to return to normal mode.

Data Hold

Press the HOLD button to freeze the reading in the display. HOLD will
appear at the top right of the display. Press the HOLD button again to
return to normal operation mode.

Backlight

Press the SETUP button to switch the backlight OFF/ON.

Setup option

The setup option is used to select the thermocouple type that matches the type
that will be connected to the meter, to switch the sleep mode OFF/ON, and to
adjust the thermocouple offset.

Note: In the setup mode, the upper display shows the menu items and
the lower display shows the selection for a given menu item.

Press and hold the SET button for 3 seconds to enter or exit the
Setup mode. When the thermometer is in Setup mode, the

5. Press and hold the SET button for 3 seconds to return to normal
mode.

Set Offset

Use the offset option in Setup (T1 menu item) to adjust the

thermometer’s readings to compensate for known temperature offset at

a specific temperature. The adjustment range is ± 5.0°C or ± 9.0 °F.

1. Plug the thermocouple into the input connector.

2. Place the thermocouple into the known, stable temperature
environment (such as an ice bath or dry well calibrator). Allow the
reading to stabilize.

3. Use the arrow keys ▲ ▼ to scroll to the “T1” option and then press
ENTER.

4. Change the offset temperature reading (upper display) by
pressing ▼until the desired temperature is reached.

5. Press and hold the SET button for 3 seconds to return to normal
mode.

Replacing the Batteries

1. Switch OFF the thermometer.

2. Loosen the battery compartment screw and remove the compartment
door.
