17 Error RTCbackup / Battery Hardware timer does not have the
current date!
If the device has been without power
supply for a longer period of time,
then the buffer capacitor may be
empty.
Check date and update it, if neces-
sary. Supply device with power for
24 hours to charge the capacitor
again.
If the error message occurred while
the Uni-Probe has been in operation
for several hours already, then the
hardware timer is faulty.
You can continue working with the
device anyway, as long as it will be
continuously supplied with power.
Otherwise, please keep in mind that
no decay compensation is carried
out as long as the Uni-Probe is with-
out power supply. As soon as possi-
ble, you have to replace the digital
board to ensure that the decay
compensation will also work when
the device is switched off.
