Page 3: Introduction
The DT80-1 and DT80-2 are thermocouple-type J/K digital thermometers. The DT80-1 is designed to be used with a single thermocouple; the DT80-2 is designed to be fed by two thermocouples configured to deliver a temperature differential. -
Page 4: Key Features
Simplicity is another asset of thermocouple thermometers. Thermocouples work by measuring the potential difference produced at the junction of two wires made of different metals but exposed to the same temperature. Since the junction is very small, a thermocouple thermometer can be used to measure the temperature at a point reachable by a probe. -

T1 T2 correct thermocouple type in the secondary display. Both the DT80-1 and DT80-2 will save their setting(s) upon shutdown and make them the default when they next power up. To hold (freeze) the display and stop updating measurements, press the key. - Page 9 the standard relative reading. Then, if the temperature rises to 30°C, the display will show 5°C (30° – 25°C). If the temperature falls to 20°C, the display will show - 5°C (20° – 25°C). Pressing the key again disables this function and restores the actual temperature reading to the display.
