4. MEASURING PROCEDURE
4-1 Temperature Measurement
For measurement of high temperatures, surfaces,
semi-solids, liquids etc., a range of hand-held
probes is available (such as TP-02A…) or, it
required, any suitable probe of the K type can be
used.
Insert the sensor plug into the socket at top edge
of the instrument, taking care to observe the
correct polarity.
Select the ℃/℉ function desired.
Use the sensing point of thermocouple to measure
the surface to be measure.
Read the stable reading.
Hold the value, if necessary, by pressing the hold
key. A second short press returns the instrument to
normal mode.

4-2 Consideration
When the sensor is first plugged into the
thermometer, or if the sensor is changed, the
plug must be allowed to stabilize at the
temperature of the socket, which is in thermal
contact with the cold junction compensation
device, for greatest accuracy is to be achieved.
This will only take a couple of minutes and only
applies if the sensor plug has previously been
exposed to an ambient temperature different to
that of the thermometer.
Note that in common with other thermocouple
thermometers the accuracy specification applies
only to the instrument itself and allowance must
be made for limits of error permitted in
thermocouple. The relevant specifications and
respective limits for K type thermocouples are:

5. MAINTENANCE
5-1 General maintenance
To keep the instrument clean, wipe the case with
a dry cloth and detergent, do not use abrasives or
solvents.
Any adjustment maintenance and repair shall be
by a skilled person about temperature
technology.
To maintain a thermocouple in good condition, shall
observe the following items.
- Avoid excess bending.
- Don't overheat the thermocouple.
- Avoid chemical reactions that can damage the
thermocouple.
5-2 Battery Replacement
When the battery voltage drop below proper
operation range the symbol will appear on the
LCD display and the battery need to be replaced..
Slide the battery cover away from the instrument
and remove the battery.
Replace with 9V battery and reinstall the cover
