The battery has to be removed, when storing device above 50 °C.
Hint: We recommend removing the battery if device is not used for a longer period of
time! Risk of Leakage
Treat device and probes carefully. Use only in accordance with above specification.
(do not throw, hit against etc.). Protect from soiling.
After switching on the instrument a segment test (all segments) is displayed, followed by
“P.off”,
if auto power off function is activated (please refer to configuration)
