If the " " indicator is displayed, it indicates a Low Battery condition and
the battery needs to be replaced. Please follow carefully the procedure
below for replacing battery.
IV. Storage and Cleaning
1. Unscrew Screw , and then open the unit by pulling the Lower-Cover
in arrow direction.
2. Remove the battery on the printed circuit board.
3. Replace the battery with new one. Make sure the battery is properly
connected to the terminals.
4. Place back the Lower-Cover by inserting its front end first on arrow
direction and then push it closely to the Upper-Cover until it snaps.
5. Make sure the rubber gasket is properly located when the unit is closed.
6. Lock the unit with the Screw .
· Use only suitable battery written on the specification.
· Do not dispose battery on household waste, fire or water.
· Remove the battery when the device will not be used for long period of
time.
· The instrument cannot measure accurately after low battery indicator is
displayed. Please replace the battery immediately.
1.) Connect the probe to the instrument through the Input Connector
· Probe can be checked if properly connected with the Burn Out feature
of this instrument.
2.) Turn the power ON.
· Upon turning ON the instrument, all the display and indicators will light
up for several seconds. This is to check if all segments of the display are
working properly. Afterwards, it will shift to its normal operating mode
with the following default items and features.
> Set at measuring mode.
> Unit set at °C.
> Thermocouple type indicator is displayed.
> Auto-Power Off indicator is displayed.
> Other indicators are not displayed.
· Auto-Power Off function is automatically enabled upon turning ON the
instrument (Please see Function list on how to disable).
· If the burnout display (----) is shown, the probe is not inserted properly.
In this case, check the probe side.
3.) Attach the sensor part of the thermocouple probe to the object you want
to measure.
· Wait until the measured value becomes stable.
· For long time measurement, use Recording function to avoid the
sudden turned Off of the instrument due to Auto-Power Off function.
4.) Turn OFF the instrument after using.
· After every use, always turn OFF the instrument.
