Plug the first thermocouple into the socket  marked T1, taking care to 
observe the polarity of the thermocouple pins. If dual sensors are being 
used, plug the second thermocouple into the socket marked T2. 

Press the       button to turn the thermometer ON or OFF. 

When first turned on, the instrument defaults to reading in Fahrenheit (°F).  
The instrument toggles between Fahrenheit (°F) and Celsius (°C) each time 
the °C/°F button is pressed.  

The present reading is held on the display by pressing the HOLD button.  
Pressing the HOLD button again releases the hold function and returns the 
instrument to continuous reading.  
In the HOLD mode, the 

UREL, MAX/MIN and °C/°F buttons are disabled, 

as indicated by two consecutive beeps when pressed. 

Pressing the 

UREL button zeroes the display and internally stores

 

the 

present

 

reading as a reference for subsequent measurements. The main 

display now shows the difference between the stored value and the new 
reading. 
Press the 

UREL button again to exit the Relative mode. 

Press the MAX MIN button to enter the MAX/MIN mode. In this mode, the 
maximum and minimum values are simultaneously retained in memory and 
updated with every new data sample. The instrument first enters the MAX 
mode, and the MAX symbol and value are both displayed. Pressing     
MAX MIN again advances the display to the MIN symbol and value. The 
next press of the MAX MIN button will cause both the MAX and MIN 
symbols to flash. This indicates that the maximum and minimum values 
have been updated in memory and the displayed reading is the present 
temperature. Each successive press of the MAX MIN button circulates the 
display mode among these options. To exit the MAX/MIN mode, press and 
hold the MAX MIN button for two seconds. 
In the MAX/MIN mode, the 

UREL and °C/°F  buttons are disabled, as 

indicated by two consecutive beeps when pressed.

By default, the instrument powers on in the ‘Auto Power Off’ mode and will 
automatically shut off 30 minutes after the last key operation. 
To disable this feature, press and hold the HOLD button and then power on 
the meter. Two successive beeps indicate that ‘Auto Power Off’ is disabled. 

When the battery voltage is at or below the minimum for proper operation, 
the        symbol will show on the display indicating that the battery must be 
replaced. 

Calibration is conducted by adjusting the following potentiometers to within 
the tolerances shown.
