Operating instructions

Selecting the Temperature Scale

Readings are displayes 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 tempe-

rature scale, press the °C or °F key.

Selecting the Display Resolution

The thermometer allows two choices of resolution:

High resolution: 0.1 °C or 0.1 °F

Low resolution: 1.0 °C or 1.0 °F

To select the alternate display resolution, press the corresponding „1°“ or „0.1°“ key.

Overload display (OL)

The digital display will indicate OL when the input exceeds the mesaurement range selected. If measuring above 

199.9°, change the resolution to 1°. Be certain to seat the thermocouple connector properly and that the leads are 

not broken.

HOLD mode

Pressing the HOLD key to enter the DataHold mode, the „D-H“ annunciator is displayed. When HOLD mode is selec-

ted, the thermometer held the present readings and stops all further measurements.

Pressing the HOLD key again cancels HOLD mode, causing the thermometer to resume taking measurements.

MAX mode

Pressing the MAX key to enter the MAX mode. The thermometer then records and updates the maximum values and 

the MAX annunciator appears on the display. Pressing the MAX key again to exit the MAX recording mode.

In the MAX mode, press HOLD key to stop recording, press HOLD again to resume recording.

Measuring the difference

You can retrieve temperature values by pressing the T1 or T2 keys.

When you press the „T1-T2“ key the difference between the two measuring channels is displayed.
