Caution
● Take care not to get burned when measuring high temperatures.
● Measuring low temperatures immediately after measuring high temperatures (or vice versa) can
quickly wear out the sensor. Leave the unit in a room-temperature environment for a while before
performing such operation.
● The measurement accuracy could be affected by an abrupt change in the ambient temperature.
Allow the unit to fully adapt to the ambient temperature before starting the measurement.
⚫
When using the unit mount on the wall
Pull out the wall-mount hook from the back of the unit and use it to hang the unit on the screw mounted
on the wall or column.
NB: Check that the unit is secured and will not fall by gently swinging it to the right and left. The
wall-mount hook could come off the mounting screw if the unit is forcibly pulled away from the wall.
6. Functions
6-1 Hold Function
When the measured values are continually fluctuating, use the HOLD function to freeze the display for
easier reading.
● Operation procedure
(1) Press the HOLD/ENTER key during measurement.
The HOLD indicator lights up to indicate that the measured values are held.
(2) To cancel, press the HOLD/ENTER key again.
The HOLD indicator goes out and the unit returns to the normal temperature measurement mode.
- The HOLD function is available when the average or relative value is displayed.
6-2. Maximum or Minimum Value Display Function
The unit records the maximum and minimum values measured since power-on.
● Operation procedure
(1) Press the MAX/MIN key during measurement.
The MAX indicator turns on and the maximum value is displayed.
(2) Pressing the MAX/MIN key again lights on the MIN indicator and displays the minimum value.
(3) Pressing the MAX/MIN key again lights off the MIN indicator and returns to the normal
measurement mode.
(4) To clear the maximum or minimum value being displayed, press the CLEAR key.
6-3. Averaging Function
The unit displays the moving average value calculated from the temperatures measured. Use this function
when the temperature of the object being measured varies widely. The calculation provides a simple
moving average with the desired number (2 to 10) set as the measurement count.
- The measurement count is set to "5" at the factory.
- The set value is retained even after power-off or during battery replacement.
- The calculated average value is not retained.
