Page 6: Operating Instructions
OPERATING INSTRUCTIONS Power Switch key turns the thermometer on or off. In the data SET mode, can not power off, must leave data SET mode then power off. °C/°F Selecting the Temperature Scale (Main display) Reading the main displayed in either degrees Celsius(°C) or degrees Fahrenheit(°F). - Page 7 The Pt385/Pt3926 key switch the T1 input selects the Pt385 or Pt3926 RTD probe as input, when main display input selected T1. When the thermometer is turned on, it is set to the probe selected that was in use when the thermometer was last turned off.
- Page 8 The true average of all the reading taken over at least 22 hours preiod can be displayed. If 22 hours is exceeded, new averages are no longer calculated. The last calcalated value is retained as the average reading, but the actual minimum and maximum reading will continue to be captured. In the this mode, press HOLD key to stop the recording of readings, all values are frozen, press again to restart recording.
- Page 9 Readings the second 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 thermometer was last turned off. To change the temperature scale, press the °C/°F key.
