4. OPERATION INSTRUCTIONS
4.1 Power-Up
Press the “ ” button to turn ON the thermometer
Press and hold the “ ” button for 3 seconds to turn OFF the thermometer.
4.2 Connection the Temperature Probe
For measurement, plug the temperature probe into the input connector.
4.3 Selecting the Temperature Scale
When the meter is first powered on, the default scale will show. The default is set on the Celsius
(°C) scale. The user may change it to Fahrenheit (°F) scale by pressing the button.
4.4 READ Operation
Press the button to view the logged readings. The display shows “ ”. Press either the
or button to scroll through the logged readings. The display shows each logged reading, its’
time stamp and memory location. Press either the , or button to exit the READ mode.
4.5 Back light Operation:
Press the button to turn on the back light. Press it again to turn it off.
NOTE: The meter will turn the back light off if there is no button pushed for 30 seconds.
4.6 Relative Operation:
When the user presses the button, the meter will memorize the present reading and the
difference between the new reading and the memorized data will be shown on the display. Press
the button again to exit the Relative operation.
4.7 Memory Operation:
The thermometer stores a single set of readings in memory each time the button is
pressed. The thermometer will hold 99 readings.
4.8 MAX/MIN Operation:
When the user presses the button, the meter will enter the MAX/MIN mode. Under this mode
the maximum and minimum values are kept in the memory simultaneously and updated with every
new data.
When the MAX symbol is display, the Maximum temperature is shown on the display.
Press the button again, the MIN symbol and the minimum temperature reading are shown on
the display.

Press the button again, the MAX and MIN symbols will blink together. All the data is updated
in the memory and the reading is the present temperature.
The user may press the button to circulate the display mode among these options.
To exit the MAX/MIN mode, press and hold the button for two seconds.
NOTE: When the meter is in the MAXMIN operation, the and buttonsare disabled.
4.9 Auto Power-Off:
By default, when the meter is powered on, it is in auto power-off mode. The meter will power itself
off after 30 minutes if no button is pushed.
To disable the auto power-off, press and hold the button and then power on the meter. There
will be two successive beeps to confirm that auto power-off is disabled.
4.10 Low Battery Condition:
The temperature meter low battery indication is:
Low battery. Replace the batteries.
5. TEMPERATURE MEASUREMENT
5.1 Correct Measurement Method:
THE TEMPERATURE SENSOR IS LOCATED AT THE END OF
THE METAL SHEATH OF THE TEMPERATURE PROBE.
TO ACCURATELY TEST INTERNAL TEMPERATURE,INSERT
THE PROBE INTO THE SPECIMEN TO A DISTANCE AT LEAST
15 TIMES THE DIAMETER OF THE SHEATH.

6. SETTING THE TIME
6.1To enter into the meter setup mode, press and hold the button, then power on the meter.
6.2 Press the button to enter “Time setting” mode. The right two digits will blink.
6.3 Press either the ▲or ▼button until the display shows the correct year, then press the
button to select. The left two digits will blink.
6.4 Press either the ▲or ▼button until the display shows the correct month, then press the
button to select. The right two digits will blink.
6.5 Press the ▲or ▼button until the display shows the correct day, then press the
button to select. The left two digits will blink.
6.6 Press the ▲or ▼button until the display shows the correct hour (24-hour format), then
press the button to select. The right two digits will blink.
6.7 Press the ▲or ▼button until the display shows the correct minutes, then press the
button to store the time in memory.
Note: Holding down either the ▲or ▼button will cause the number to change more quickly.
7. CLEARING MEMORY
When the memory is full, “MEM” will appear and blink on the display and logging stops.
To enter into the “Clear memory” mode, press and hold the button, then power on the meter.
The display shows the number from 5 decreasing to 0.

8. TEMPERATURE METER CALIBRATION SETUP
The below table diagram shows each button function when in the
calibration mode.
Note: Turn the Auto Power-Off off before attempting the following
SETUP. Setup mode is cancelled if the button is pressed during
the procedure.
8.1 Temperature Calibration
Place the temperature probe in a known, stable temperature environment. Allow the reading to
stabilize. In the “Setup” mode, change the offset until the display reading matches the calibration
temperature.
8.1.1 To enter the setup mode, press and hold the and button, then power on the meter
8.1.2 Press the button to enter the calibration mode. (in 3 seconds)
8.1.3 Press the button to enter the calibration mode. (in 3 seconds)
8.1.4 Press the or button to confirm the present Temperature value.
8.1.5 Press the button twice to confirm selection.
Note: To abort during the process, press the button to exit calibration mode.
8.2 Recall Default factory setting value
8.2.1 To enter the setup mode, press and hold the and buttons, then power on the meter.

8.2.2 Press the button to enter the calibration mode. (in 3 seconds)
8.2.3 Press the button to enter the recall mode. (in 3 seconds)
8.2.4 Press the button to confirm reverting back to the “Default factory setting value”
8.2.5 Press the button to confirm selection.
Note: To abort during the process, press the button to exit calibration mode.
9. POWER PREPARATION
9.1 Battery Loading
Remove the battery cover on the back and insert one 9V battery.
9.2 Battery Replacement
When the battery voltage drops below the operating voltage, the “Low battery indicator” will
appear. Replace a 9 Volt battery immediately to ensure the unit functions properly.
9.3 AC Adapter Connection
When the AC adapter is used, insert the plugs of the adapter into the DC9V connector on the side
panel.
Note: When the AC adapter is connected while a battery is inserted, the unit will be powered from the
adapter (the AC adapter has priority).
10. Maintenance
In order to ensure the accuracy of the thermometer for a longer period of time you should calibrate
it once a year.
Clean the device and the window of the display with a clean, lint-free, antistatic and dry cleaning
cloth.
Do no use cleaning agents that contain carbon, benzenes, alcohol or anything similar to clean the
product since these substances can damage the surface of the measuring instrument. Moreover, the
fumes from these cleaning agents are hazardous to your health and explosive. Do notuse tools with
sharp edges, screwdrivers, metal brushes or anything similar to clean the device.
