Adj.T Clock adjustment
Displays the clock correction value. Through the reciprocal the number of seconds
can be established for the interval after which the DL210 automatically subtracts or
adds 1 second to compensate the inaccuracy of the clock crystal.
It should be noted that the ambient temperature of the device has a very large
influence on the clock accuracy. In particular low temperatures lead to the clock
running slower and so the measurement period of the device is longer.
Save Manual backup
Here, it is possible for the user to carry out a manual backup of all system data,
date, time, counter readings and the determination of the maxima in the current
month. This is a backup so that, for example with an ensuing battery replacement,
it is ensured that the data is not lost. In addition, the new battery should first be
connected before the old one is removed.
Clr.A Clear measurement archives
All measurement archives (not log book and changes log book "audit trail") are
cleared, incl. their readout notes. This function is particularly practicable after the
measuring point of the DL210 is changed.
In order that the archives are not unintentionally deleted, the following safety
mechanism is integrated: To clear the archives the DL210 serial number (found on
the name-plate of the device) must be entered.
Clr.V
Clear counters
,
incl. archives
After calling by ENTER, an "0" is positioned right-justified in the display. After
selecting "1" with or and termination with ENTER, the function is initiated,
i.e. all
counter readings
,
archives
(measurement period and month archives)
and
readout notes
are cleared. Similarly, all intermediate values associated with
volume and flow calculations are deleted.
F
This function may only be executed when there is no link (by remote
data transfer or optical interface) to the DL210, because it would be
uncontrollably interrupted.
