Safety Precautions
For safe usage of this device, please observe all statements regarding
precautions and warnings in this instruction manual.

ATTENTION
1. Operation- Do not use this device near machines that emit strong
electromagnetic fields or objects that store static electricity.
- Do not drop or subject this device to strong impact.
- Do not use or store this device where it will be exposed to water or inplaces with wet conditions.
- Do not use or store this device where it can be exposed to direct
sunlight, dust, high temperature and high humidity.
- See the battery case markings to ensure that the battery is properlyinstalled.
- For accurate measurements, do not subject this device in measuring
sudden change of temperatures.
- Remove the battery when the device will not be used for a long periodof time.
- Do not attempt to disassemble or modify this device.
2. Thermocouple Probe- Do not measure beyond the temperature limits of the thermocouple
probe being used.
- Do not use thermocouple probe in places where presence of electric
shock is suspected.
- Avoid using the thermocouple probe to measure materials that may
cause rust or corrosion. If used, wipe the thermocouple probe with adry clean cloth after every use.
- Do not attempt to disassemble or bend the miniature connector of thethermocouple probe.
- Avoid bending, dropping or hitting the thermocouple probe, evenwhen not in use.
- When measuring surfaces, make sure that the thermocouple probe isin contact with the surface perpendicularly to record accurate
measurements.
- In measuring surfaces of non-metallic materials, transfer of heat takes
longer than normal, therefore, make measurement time longer to get

2. Measuring Procedure1.) Press the [POWER] button to switch-on the unit.
2.) Select the sensor type (Type K/J/T/E/R) by pressing the [SENSOR] button.
3.) Insert the thermocouple probe into the "Thermocouple Input Socket".
4.) The temperature reading will then be shown on the display.

3. Functions Operation
a. Data Holde. Offset Value Adjustment

b. Data Record (Max / Min Reading)1.) To start recording the measurement data, press the [REC] button once.
The display will show the "REC" symbol.
2.) While the "REC" symbol is on display, press the [REC] button once todisplay the Maximum measured data recorded. The "Max" symbol will
also appear on the display.
Press the [REC] button once again to display the Minimum measured
data recorded. The "Min" symbol will appear on the display.
To view back "Max"("Min") measured data, press [REC] button, alternately.
3.) To exit from Data Record function, press the [REC] button for at least 2
seconds.

c. Relative Measurement

This unit is calibrated properly before shipping it out to customers.
Due to some reasons, the measured value may drift a few degrees fromthe correct value.Therefore, the Offset Adjustment can be used tocorrect this error in measurement.
Take note that doing the procedures below will change the factory
setting calibration temperature of the unit.Turning Off the unit will notmake it return to the original setting.Therefore, please be careful inadjusting!!!You should note down the values ??before and after offset
adjustment in order to restore to the factory settings.
If accidentally changed, please have the unit calibrated.
1.) While on measuring mode, press and hold the [HOLD] and [REC] buttons
simultaneously. The same measured value (smaller size) will show on thelower right corner of the display. (See Fig. 1)
2.) While pressing the [HOLD] and [REC] button simultaneously, press either
the [Blank Button] or [RELATIVE] button to adjust the temperature up or
down respectively. (See Fig. 2)
3.) After the desired offset value is set, release all the buttons. The small digits
in the lower right corner of the display will disappear and the offset value
setting is completed. (See Fig. 3)

1.) This unit will automatically switch off if none of the buttons are pressed
for approximately 10 minutes.
Note: The Auto Power Off feature is disabled while in Data Record
function.
