5. Object being measured
6. Thermometer
   

Connection
A. Insert thermocouple into input jacks
B. Short press to turn on the device.
C. Setup the thermocouple type (according to the type being used)
Note: If the thermocouple is not connected to input jacks, or in open circuit, “—-” appears on the screen. If over range occurs, “OL” appears.

Temperature display
Long press to select temperature unit.
A. Place the thermocouple probe on object to be measured.
B. Temperature is displayed on the screen.
Note: It takes several minutes to steady the readings if thermocouples are just inserted or replaced. The purpose is to ensure the accuracy of cold junction compensation

Temperature difference
Short press, temperature difference (T1-T2) is displayed.

Data hold
A. Short press to hold the data displayed. HOLD symbol appears.
B. Short press again to switch off data hold function. HOLD symbol disappears.

Backlight ON/OFF
A. Long press to turn on backlight.
B. Long press again to turn off backlight.

ΜΑΧ/ΜΙN/AVG value
Short press to cycle switch between MAX, MIN, AVG or regular measurement. Corresponding symbol appears for different modes. E .g MAX appears when measuring maximum value.

Thermocouple type
Long press to switch thermocouple types (K/J). TYPE:K or TYPE: J are type indicators.

Battery replacement
Please replace the battery as figure 4 shown.
