Translation of the Original Instructions for Use
Switching on the hand-held
measuring instrument
To turn on the hand-held measuring in-
strument, press and hold the c button for
about 1 second.
The hand-held measuring instrument tries
to communicate with the connected
probe during the activation procedure.
This takes about 4 seconds. If no probe is
connected or the probe cannot be
reached due to another reason, an error
message appears on the display.
If the probe has been successfully found,
the measurement background appears on
the display according to the operating
mode.
During the switching-on phase, the “Cali-
bration” message appears at the bottom
of the display.
This means that the hand-held measuring
instrument calibrates itself to the lance-
head-shaped probe. After this, the SONO
WZ is ready for use.
If no connection with the probe is possi-
ble in spite of repeated attempts, check
whether the probe has been connected
correctly. If this does not help, please
contact PERI.
