measurement in microwave ovens.  
9. “T1 T2/T1-T2/ “ Button  
Press “T1”, “T2”, “T1-T2” button to select input mode T1,  
T2 or T1-T2. The input selection indicates which input is  
selected for display, T1 thermocouple, T2 thermocouple or  
the differential between the two thermocouples (T1-T2).  
1. “ ” Power Button  
Press the “ button to turn on or off thermometer.  
2. “ /°C/°F” Button  
Readings are displayed in either degrees Celsius (°C) or  
degrees Fahrenheit(°F). When the thermometer is turned  
on, it is set to the temperature scale that was in use when  
the thermometerwas last turned off. To change the tem-  
perature scale, press the “°C/°F” button.  
CAUTION  
Repeated sharp flexing can break the thermocouple  
leads. To prolong lead life, avoid sharp bends in the  
leads, especially near the connector.  
GENERAL  
Display: 3_ digit liquid crystal display (LCD) with maxi-  
mum reading of 1999.  
Overload: ”-OL” is displayed.  
1. Insert the thermocouple into a known temperature (T)  
until the display stabilizes near the known temperature  
(T). example: ice point at 0°C or boiling water 100°C  
2.Press and hold the “ADJ/HOLD” button for 2 seconds  
until the display starts to blink.  
3. Press “ ” or “ ” to adjust the displayed value.  
4. It can be adjusted 6°F ( 3°C) from default. If you  
can not adjust your reading to match the known tem-  
perature (T), please check your T/C type. The meter  
may require calibration.
