MODEL 308 MINI DUAL CHANNEL THERMOMETER

4.0Operating Instructions

4.1Preparation for Measurement

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.

4.2Power

Press the button to turn the thermometer ON or OFF.

4.3Selecting the Temperature Scale

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.

4.4Data-Hold Function

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.

4.5Relative Operation

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.

4.6MAX/MIN Operation

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.
