Carrying out a measurement
In general:
The temperature measuring range of the digital thermometer reaches from -200° C
to +1370° C.
The temperature range of the supplied sensor reaches from -50° C to max.! 200° C.
Do not measure temperatures that are higher than +200° C (= 392° F) with the sup-
plied sensor.
Take into account that "outside" the temperature range +18° C to +28° C (= range of
the guaranteed measuring accuracy) it is only permitted to expose the thermoele-
ment to the temperature that is to be measured.
Measuring:
Proceed as follows to measure the temperature:
1. Connect, depending on the demand, either one or two or four K type temperature
sensors (you find two attached) to the thermometer an turn it on.
Do not connect any voltages. This might destroy the device.
2. Hold the temperature sensor/s (wire end/s) at/into the dead measuring medium
(heat sink etc., but no caustic or combustible liquids!).
