exceeded. The last measured value (Y2 in Fig. 3) is reported and set as a
new base for the following measurements.

Fig. 3 Integrating dead-band supervision
Uses can select the periodic reporting of measured value in time intervals
between 1 and 3600 s. The measuring channel reports the value even if it
has not changed for more than the set limits of amplitude or integrating
dead-band supervision. To disable periodic reporting, set the reporting
time interval to 0 s.
The newly measured value is reported:
• After each time interval for the periodic reporting expired, or
• When the new value is detected by the dead-band supervision func-
tion
You can select the amplitude dead-band and the integrating dead-band.
You can set periodic reporting in time intervals between 1 and 3600 sec-
onds.
Periodic reporting can operate serially with the dead-band supervision.
This means that the new value is reported only if the set time period
expired and if the dead-band limit was exceeded during the observed time.
The reporting of the new value depends on setting parameters for the
dead-band and for the periodic reporting. Table 1 presents the dependence
between different settings and the type of reporting for the new value of a
measured quantity.
