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

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 is
pressed.
· Turning ON the instrument while pressing the HOLD key disables the Auto-
Power Off function and the " AUTO OFF " 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 the
power 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 and
returns the instrument to the orginal measuring state.
To convert the measured data into °C or °F unit , press this key. Unit °C or °F
will be shown on the display.
· Convertion can take place during Hold, Recording, Relative and Data
Recall function.
Pressing this key will display the difference (relative value) between the
measured value (D1) just before the key is pressed (reference value) and the
succeeding measured value (Dx). indicator appears on the display.
Relative Display = DX - D1
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. indicator appears while recording.
· 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.

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.
(This procedure can not be made while in Relative function.)
· 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.

DIGITAL THERMOMETER MANUAL TC-400A
If the " " indicator is displayed, it indicates a Low Battery condition and
the battery needs to be replaced. Please follow carefully the procedure
below for replacing battery.
IV. Storage and Cleaning
1. Unscrew Screw , and then open the unit by pulling the Lower-Cover
in arrow direction.
2. Remove the battery on the printed circuit board.
3. Replace the battery with new one. Make sure the battery is properly
connected to the terminals.
4. Place back the Lower-Cover by inserting its front end first on arrow
direction and then push it closely to the Upper-Cover until it snaps.
5. Make sure the rubber gasket is properly located when the unit is closed.
6. Lock the unit with the Screw .
· Use only suitable battery written on the specification.
· Do not dispose battery on household waste, fire or water.
· Remove the battery when the device will not be used for long period of
time.
· The instrument cannot measure accurately after low battery indicator is
displayed. Please replace the battery immediately.
1.) Connect the probe to the instrument through the Input Connector
· Probe can be checked if properly connected with the Burn Out feature
of this instrument.
2.) Turn the power ON.
· Upon turning ON the instrument, all the display and indicators will light
up 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 the
instrument (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 want
to measure.
· Wait until the measured value becomes stable.
· For long time measurement, use Recording function to avoid the
sudden 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.
