Operating manual
3.2 Operation and maintenance advice
Battery operation:
If ‘bAt’ is shown in the lower display the battery has been used up and needs to be
replaced. However,
the device will operate correctly for a certain time. If ‘bAt’ is
shown in the upper display the voltage is too low to operate the device; the battery
has been completely used up.
The battery has to be taken out, when storing device above 50 °C.
We recommend taking out battery if device is not used for a longer
period of time.
Treat device and sensor carefully. Use only in accordance with above specification.
(do not throw, hit against etc.). Protect plug and socket from soiling.
Connecting/changing sensors
To disconnect thermocouple sensor plug do not pull at the cable but at the
plug
Selection of types of thermocouples:
Prior to carrying out a
measurement make sure to check if device is set to the thermocouple
type used (type is shown on the display shortly after unit has been
switched on). Unless the correct thermocouple is set, temperature
measurements will be incorrect!
