Error display during measurement
When function 3.2.5 "ERROR. MSG." is set to YES, any error occurring during
measurement is indicated in the display and alternates with the measured value for
as long as the error is present.
In addition, all errors are stored. Press the keystroke combination
to get into the error list. You can page through the list with key
, and
acknowledge the errors at the end - if required - by "QUIT YES". Press key
twice
to return to the measuring mode.
Fatal errors (FATAL ERROR), that are detected when the device is started up,
render operation of the BM 70 A impossible.
