ATTENTION
Operation
· 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 temperature
change 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
· Do not drop the probe or strike into hard surface.
· Do not bend the probe connector by applying strong force from the
upper 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 is
is suspected.
· Avoid using the thermocouple probe in measuring materials which
can cause corrosion.
· Take a long time when measuring non-metallic surface temperatures
due to poor thermal conductivity.
· When measuring surface temperature, make sure that the
thermocouple probe is in contact with the surface perpendicularly for
accurate measurement.

ON / OFF Key automatically turns OFF in approximately 10 minutes after the last key is
pressed.
· Turning ON the instrument while pressing the HOLD key disables the Auto-
ON
Power Off function and the " AUTO OFF " indicator will disappear
OFF
· 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
Burn Out
display (----).
----
( ) · If the instrument is in Burn Out state, just connect the probe, then turn the
power OFF then ON to return the instrument to the normal operating
condition.
HOLD Key
To hold the measured value temporarily, press this key once.
will appear on the display. And press again to unhold the measured value and
HOLD
returns the instrument to the orginal measuring state.
Unit Select Key
To convert the measured data into °C or °F unit , press this key. Unit °C or °F
will be shown on the display.
°C
· Convertion can take place during Hold, Recording, Relative and Data
°F
Recall function.
Pressing this key will display the difference (relative value) between the
Relative Function Key
measured value (D1) just before the key is pressed (reference value) and the
succeeding measured value (Dx).
REL
Pressing this again returns the instrument to normal measured value display.
Pressing this key will start the instrument to record the Max / Min value until
such time that it is pressed again.
MAX/MIN Record Key
R E C
MAX - MIN
· Recorded Max/Min value is stored in the internal memory after the
recording (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 be
deleted 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.
Memory In Function
There are two ways to store measured value on memory.
· First, put the measurement on HOLD then press the Recording key.
HOLD
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.
REL
(This procedure can not be made while in Relative function.)
· The data stored can only be changed by the above two ways.
R E C · Also, the data stored will not be erased even the instrument is turned OFF.
MAX - MIN
Press this key to recall the recorded and stored values. The manner of
rotation is shown below.
