2.) Slide the battery cover to remove it.
3.) Remove the battery from the battery compartment.
4.) Replace it with a new battery and make sure that it is installed properly according tocorrect polarity.
5) Replace the battery cover to the unit.
*The instrument cannot measure accurately after low battery indicator is displayed.
Please replace the battery immediately.

4. Cleaning
Wipe off dust and other dirt on the unit using a dry cloth.
CAUTION
Do not wipe the unit with benzene or thinner, this may cause the unit to break andproduce white marks on the casing.

CAUTION- The thermocouple probe is non- insulated.
Avoid measuring places where it cancause electric shock.
- Do not deform thermocouple probes toavoid errors in measurement.
- Do not use the Thermocouple probe tomeasure over its maximum temperature
limit.

2. Measuring Procedure
2.1 Single Probe Measurement
1.) Insert the thermocouple plug into the “A” input terminal.
2.) Switch the Power Switch to position “A”
3.) Engage the thermocouple probe to the object to be measured.
4.) After the display stabilize, take the reading of the temperature.
2.2 Dual Probe Measurement
1.) First, insert thermocouple plug of Thermocouple No. 1 into the “A” input terminal.
2.) Then, insert the thermocouple plug of Thermocouple No. 2 into the “B” input terminal.
3.) Engage the thermocouple probes to their respective objects to be measured.
4.) Switch the Power Switch to position “A” or “B” depending which of the 2 thermocouple
probes measurement will be displayed.
5.) After the display stabilize, take the reading of the temperature.
CAUTION- When measuring non-metal objects or surfaces, heat conduction is poor.
Please take measurement longer than normal.
- For measurement reading to stabilize faster, do not measure suddenchanging temperatures.
- Make sure that the polarity is correct when connecting thermocouple probe
plugs to the unit.
- To get accurate measurements, make sure that the thermocouple probes andthermometer unit equalize with surrounding temperature.
