- Worktime
– operating time for the archiving interval.
1.5.4.2. Changes in the operating mode of the device are recorded in the mode
log, which can contain up to 1000 records.
Each mode log entry records:
- Sequence number of the record
- Name of the set operating mode of the device
- Date and time of mode setting.

NOTES:
1. The flow rate in the reverse flow direction as well as the negative values
of the total volume and the volume of the reverse flow are indicated with
a minus.
2. The total volume is defined as the sum of the volumes accumulated in the
forward (positive) and reverse (negative) flow direction, considering the
sign of the flow direction.
3. An overflow of counters occurs if V

. After the counter is full,
the display continues from zero.
In the SERVICE and ADJUSTMENT modes, the indicator is always
on. In the WORK mode, the indication is switched on by pressing the
button and is switched off after the last pressing it in the interval set in the
Worktime field in the Service tab of the Monitor BUF (310) application.
Switching the indication of the parameters given in Table 5 is per-
formed on the ring by sequential pressing the button located on the front
panel of the device.
