4.1 POWERUP
Press the key to turn the thermometer On or OFF.
4.2 CONNECTING THE THERMOCOUPLES
For measurement, plug the thermocouple into the input connectors.
4.3 SELECTING THE TEMPERATURE SCALE
When the meter was rst powered on, the default scale setting is set
at Celsius (°C) scale. The user may change it to Fahrenheit (°F) by
pressing “ °C/°F ” button and vice versa to Celsius.
4.4 DATAHOLD OPERATION
The user may hold the present reading and keep it on the display by
pressing the“HOLD”button. When the held data is no longer needed,
one may release the data-hold operation by pressing “HOLD” button
again. When the meter is under Data Hold operation, the “▲REL”
, and “ °C/°F ” button are disabled.
4.5 T1,T2,T1T2 DISPLAY CONTROL
One may select T1,T2 or T1-T2 to show on the main display by
pressing button. When T1 or T2 is select to show on the main
display, the other temperature will be shown on the second display.
When one select T1-T2 to show on the main display, T1 and T2 will be
shown on the second display alternately.
4.6 RELATIVE OPERATION FOR MAIN DISPLAY
When one press the “▲REL” button, the meter will memorize the
present reading and the dierence between the new reading and
the memorized data will be shown on the display. Press the “▲REL”
button again to exit the Relative operation.
4. OPERATION INSTRUCTIONS
P. 7
4.7 MAX/MIN/AVG OPERATION FOR MAIN DISPLAY
When one presses the button the meter will enter the
MAX/MIN mode. Under this mode the maximum value, minimum
value and average value of latest 8 data is kept in the memory
simultaneously and updated with every new data.
When the MAX symbol is display, the Maximum is shown on the
display.
Press again, then the MIN symbol is on the display and also the
minimum reading.
Press again, the AVG symbol is on the display and also the
average reading.
Press again, MAX, MIN and AVG will blink together. This means
that all these data is updated in the memory and the reading is the
present temperature.
One may press to circulate the display mode among these
options.
When the meter is under operation, “▲REL” and “ °C/°F ” are
disabled.
To exit the MAX/MIN mode, one may press and hold for two
seconds.
4.8 AUTO POWER OFF
By default, when the meter is powered on, it is under auto power o
mode. The meter will power itself o after 30 minutes if no key
operation or RS232 communication. Key combination at power on
or RS232 communication can disable auto power o. One may press
and hold “HOLD” button and then power on the meter and there will
be two successive beeps to indicate that auto power o is disabled.

4.9 LOW BATTERY CONDITION
When the battery voltage is under proper operation requirement,
the symbol will show on the LCD and the battery need to be
replaced with new one.
4.10 CALIBRATION POINT
Room Temperature 23 ± 3°C
Normally, performing oset Calibration with thermal stabled ice
water through VR1 will give a very good calibration result.
4.11 DIGITAL OUTPUT
The Digital Output is a 9600bps N 81 serial interface.
The RX is a 5V normal high input port.
The TX is a 5V normal high output port.
