2.2 Operating and Maintenance
Battery operation:
If the "
BAT
" symbol is displayed at the bottom left of the display, the battery is weak and should be replaced
soon. However, the device will still operate for a certain length of time.
If an additional "

).
The battery has to be removed, when storing device above 50°C.
We recommend taking out the batteries if device is not used for a longer period of time.
Treat device and probes carefully. Use only in accordance with above specification. (do
not throw, hit against etc.). Protect plug and socket from soiling.
Make sure that the device and the probe plug are always exposed to the same
temperature. Therefore, do not hold the probe plug in your hand too long and do not
expose the device to an additional heat source; otherwise faulty measurements can occur.
Wire probes, e.g.: GTF 300 can be shortened or, in case of a break, repaired by stripping
about 10mm of the insulation off of the wire ends and twisting them together.
Measurement is not possible with open wire ends.
