Note!
If the "ThermoLog" menu is activated, the corresponding icon also appears as
so-called "Tray Icon" on the bottom right side in the "Windows" window, to the
right of the loudspeaker symbol.
How to perform a measurement
The temperature measurement range of the digital thermometer ranges from -200°C
to +1370°C.
The temperature range of the enclosed sensor ranges from -50°C to max.! 200°C. Do
not use the probe delivered with the equipment to measure any temperatures greater
than +200°C (=392°F).
It must be taken account of the fact that "outside" of the temperature range from
+18°C to +28°C (=range of guaranteed measuring accuracy) only the thermo probe
may be exposed to the temperature to be measured.
For temperature measurement, proceed as follows:
1. Connect either one or two of the enclosed temperature sensors to the thermome-
ter, as required for your purposes, and switch it on.
Do not connect voltages! This might destroy the device.
2. Hold the temperature sensor(s) (line end(s)) to/in the de-energized measuring fluid
(heat sink, etc., but not in caustic or inflammable fluids!).
Notes!
In the small display on the left, the differential temperature of T1 minus (-) the
T2 temperature is continuously determined and indicated.
In the small display on the right, the temperature of T2 appears permanently.
If one of the temperature sensors is not connected, or even interrupted, "- - - -
" appears instead of a measured value. In this case, difference determination is
not performed / displayed either.
Disposal
If the digital thermometer 306 is not operable or defective beyond repair in spite of
correct supply (9 V block battery), it must be disposed of according to the applicable
legal requirements.
