5 Operation
1. Quickly press the button for less than a
second and release to turn the thermometer
ON or OFF.
*The power cannot be turned off under SETUP
mode; please exit SETUP mode first.
2. Select Celsius °C, Fahrenheit °F or Kelvin K;
the temperature unit will be switched once
every time the button is pressed.
3. Move the front of the thermocouple towards
the test subject to measure its temperature.
4. Read the measured value on the LCD.
5.1 Backlight
While under ON status:
Press and hold the button for over 2 seconds to
turn on the backlight; press and hold the button
for over 2 seconds again to turn off the backlight
function.
＊The backlight will automatically turn off after being lit for
15 seconds.
5.2 Alarm Function:
Press and hold the button for 2 seconds and the
LCD will display whether the alarm function is ON or
OFF. A maximum and minimum value for the
temperature can be set manually; when the
temperature reading exceeds this range, the buzzer
will give an alarm until the temperature returns to
within the range or the alarm function is turned OFF.

4
5.3 Thermocouple Type Selection (TYPE)
Every time the button is pressed for less than a
second, the termocouple type will switch in the
order of K/J/E/T/R/S/N.
5.4 Manual Record (Rec)
Press and hold the button for over 2 seconds to
save 1 temperature data; 00001 will be displayed on
the LCD and will increase by 1 every time it is
pressed.
Repeat this process, the manual record will
continue to add 1,0002 will be displayed.

5
5.5 Data Hold
Press the button to turn on or turn off hold the
data and stop updating.
When HOLD is enabled, all buttons will stop working
except for the power button.
5.6 Auto Power Off
The device is preset to automatically shut down
after 15 minutes of inactivity.
Press button more than 1 second to turn on or
turn off auto power off.

6
5.7 Relative Value Measurement
Function(REL):
Use only one thermocouple to compare the
difference between 2 temperatures. For example if
the first temperature was measured to be 25°C,
press the button now and the LCD will display
0°C; then a second temperature was measured to
be 30°C, and the LCD will display 5°C (30-25=5°C).
Press the button again to turn off this function.
The main display shows the REL value and the
secondary display shows the temperature value
currently being measured.
To display the relative value of another channel,
please press and hold the button to switch
between T1 and T2 displays.

7
5.8 Offset Setting (OFFSET):
Users can manually set the offset value to use as
compensation for the error of the thermocouple
cable that you are currently using.
1. Press and hold the (OFFSET) button for 1
second to enter settings for the offset value.
2. Press the top and bottom buttons to
increase or decrease the offset value; the unit for
every time it is pressed is 0.1°C/°F/K. The setting
range is between±5°C, ±5K and ±9°F.
3. Press the (Setup) button to save the setting
and exit the setting mode.
To set the offset for another channel, please press
the button to switch.
The device will automatically save the offset value
set as the default value for the next power ON.

8
5.9 T1-T2 Display:
This meter provides the display for the difference
between the T1 temperature and T2 temperature.
When the button is pressed, it will display the
value of T2 subtracted from T1.
Press the button again to turn off this function.
The main display will display the T1-T2 value and
the secondary display will display the temperature
value currently measured.
To display the temperature measured on another
channel on the secondary display, please press and
hold the button to switch.
Every time the button is pressed and held, the
main/secondary display position of T1 and T2
will be switched.

5.10 Maximum /Minimum/ Average Value:
Quickly press the button for less than one
second and then MAX/MIN/AVG and measurement
elapsed time will be activated simultaneously. Every
time the button is pressed, the display will cycle
as shown in the figure below.
Press and hold the button for over 1 second to
turn off this function.
The main display will display the MAX, MIN or AVG
value of the current channel and elapsed time for
the measurement; the secondary display will display
the current temperature value.
To display the maximum value, minimum value and
mean value of another channel, please press and
hold the button to switch displays between T1
and T2.
