ONOperation· Do not use this device near machines that emits strong
electromagnetic field or object that store static electricity.
· Do not drop or subject this instrument into strong impact.
· Do not attempt to disassemble or modify this instrument.
· To ensure stable measurement, do not apply rapid temperaturechange to the instrument.
· Do not immerse the instrument in water. If it is immersed in water
accidentally, immediately pull it out and then check and ensure that
there is no water penetration.
Thermocouple Probe

OFFBurn Out(------)HOLD Key· Do not drop the probe or strike into hard surface.
· Do not bend the probe connector by applying strong force from theupper and lower side.
· Do not measure beyond temperature limits of the thermocouple
probe being used.
· Do not use the thermocouple probe in places where electric shock isis suspected.
· Avoid using the thermocouple probe in measuring materials which
can cause corrosion.
· Take a long time when measuring non-metallic surface temperaturesdue to poor thermal conductivity.

Functions
ON / OFF KeyATTENTION

Misuse of this device may lead to injury to theuser or damage to the device.

HOLD

Pressing this key will turn ON and OFF the instrument· Since this instrument has the Auto-Power Off function, the power
automatically turns OFF in approximately 10 minutes after the last key ispressed.
· Turning ON the instrument while pressing the HOLD key disables theAuto-Power Off function and the "" indicator will disappear· In addition, Auto-Power Off is disabled even during recording.
· In any case, it is advisable to manually turning OFF the power after
finishing the measurement.

When the probe is not properly connected to the instrument, or the probe itself
is broken, the unit will be in Burn Out state and will have a burn out display(------).
· If the instrument is in Burn Out state, just connect the probe, then turn thepower OFF then ON to return the instrument to the normal operating
condition.

To hold the measured value temporarily, press this key once.
indicator
will appear on the display. And press again to unhold the measured value andreturns the instrument to the original measuring state.

II. Operation Procedure1.) Connect the probe to the instrument through the Input Connector· Probe can be checked if properly connected with the Burn Out featureof this instrument.
2.) Turn the power ON.
· Upon turning ON the instrument, all the display and indicators will lightup 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 theinstrument (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 wantto measure.
· Wait until the measured value becomes stable.
· For long time measurement, use Recording function to avoid thesudden 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.

Relative Function Key
REL

Pressing this key will display the difference (relative value) between themeasured value (D1) just before the key is pressed (reference value) and thesucceeding measured value (Dx).
indicator appears on the display.
Relative Display = Dx - D1
Pressing this again returns the instrument to normal measured value display.

The keys of this instrument can be switched with only a slight pressure.
Make sure that the instrument is not mistakenly set to a state other thanthat intended.

If the "" indicator is displayed, it indicates a Low Battery condition andthe battery needs to be replaced. Please follow carefully the procedure
below for replacing battery.

REC· Recorded Max/Min value is stored in the internal memory after therecording (The data can be read later).
However, if Recording is started again, the previously stored Max/Min data
will be replaced with new recorded values.
· When this key is pressed during Relative function, the Max/Min values
recorded are the actual measured values (Dx) instead of relative values.
· Even if the power is turned OFF, the Max/Min values stored will not bedeleted and can still be read after the power is turned ON.
· During Recording, Auto-Power Off function is disabled and enabled again
after the Recording.

There are two ways to store measured value on memory.
· First, put the measurement on HOLD then press the Recording key.
Simultaneously, the HOLD state is released and return to measuring mode.
· Second, is by shifting the measurement mode to Relative function.
The reference value D1 will be stored in the memory.
· The data stored can only be changed by the above two ways.
· Also, the data stored will not be erased even the instrument is turned OFF.

Press this key to recall the recorded and stored values. The manner ofrotation is shown below.
