After having terminated the recording by the measure-
ment instrument the message - - - - is displayed on the
main screen of the measurement instrument. Further
secondary displays, such as memory address number
and time remain displayed if the HOLD mode has been

hours, the thermometer switches off automatically.
The saved values are maintained in the memory.

teries) and distribution voltage failure.
