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.

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

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.

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 button s 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 setti

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.

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.
