Bosch UniversalHumid Original Instructions Manual page 28

28 | English
Cause
Wood moisture content is outside the
measuring range (too low) or measurement
has not been performed correctly
The measuring tool monitors the correct operation in each measurement. When a defect
is determined, "Err" and the warning symbol (c) are shown in the display. Switch the
measuring tool off and on again. If the error persists, remove the batteries and then rein-
sert these after a few seconds. If the aforementioned corrective measures cannot correct
an error, send the measuring tool via your dealer to be checked by an after-sales service
agent for Bosch.
