Page 6: Operating Instructions
OPERATING INSTRUCTIONS Power Switch key turns the thermometer on or off. In the MIN MAX record mode can not power off, must leave MIN MAX record mode then power off. °C °F Selecting the Temperature Scale Readings is displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F). - Page 7 The input selection indicates which input is selected for display; T1 thermocouple, T2 thermocouple or the difference between the two thermo- couples (T1-T2), when the thermometer is turned on, when the thermom- eter is turned on, it is set to the input selected that was in use when the thermometer was last turned off.
