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
displayed overflow, the meter still carries out the measurement.
l
The meter controls currently the value of the introduced parame-
ter 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-2xx 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 (HOUr mode) is displayed in the 24 hours’
format, in the form hh.mm, where hh – current time, and mm – current
minute..
