HYDAC HMG 500 - Handbuch (Seite 21)

Please note that the differential is
always A - B and it might therefore be
necessary to transpose the
connection of the sensors to channel
A and B.
To give the differential, press one of
the arrow keys left or right next to
„Mode“. If pressed again, the
differential display switches off.
The differential is possible both for the
actual measured values and for the
minimum and maximum values.
The HMG 500 records the minimum
and maximum values in addition to
the actual measured values.
Measuring the min/max values has a
special importance which is explained
in more detail below.
The Minimum value is the lowest
value which a measuring parameter
has reached in a certain time period,
the Maximum value is the highest
value which a measuring parameter
has reached in this time period.
If Reset is pressed the min/max
values are set to the actual measured
values at that moment. This applies to
all sensors which are connected.
