Caution !
l
In case of alarms of n-on, n-off, on, off types the write of PrL>PrH will
cause the alarm switching off.
l
In case of a measuring range overflow, the reaction of the relays is
compatible with written PrL, PrH, tYP parameters. In spite of the dis-
played overflow, the meter still carries out the measurement.
l
The meter controls currently the value of the introduced parameter
at the moment. In case when the introduced value overflows the upper
range given in the table 1, the meter will make automatically the change
into the maximal value. Similarly, in case when the introduced value
overflows the lower change range given in the table 1, the meter will
make automatically the change into the minimal value.
5.4.6 Display Format
The DHB-4xx meter adapts automatically the display format (precision)
to the value of measured quantity. So that the function could be fully
used, one must choose the format 0.0000, then the meter will display
the measured value with the possible highest accuracy. This function
does not operate for the time display, where the format is set automa-
tically. The current time (mode HOUr) is displayed in the 24 hours’
format, in the shape hh.mm, where hh – current hour, and mm – current
minute.
Caution: Remember that the display with a higher resolution is not al-
ways desired, it can conduct to a deterioration of the indication stability.
