HYDAC HMG 500 - Handbuch (Seite 20)

Operating instructions
When the HMG 500 is switched on, a
two-line display of measured values
appears:
•
1st line:
Measured value on Channel A +
unit
•
2nd line:
Measured value on Channel B +
unit
Of course this is only the case when
sensors are connected. In addition the
Portable Data Recorder is only
designed for connecting to HYDAC
HSI sensors. If a channel is not being
used, a dotted line is displayed.
You also have the possibility of
measuring and displaying a value
differential between channel A and B.
The differential value Channel A - B
can only be measured if two sensors
with identical measuring ranges are
connected. The differential value
always appears in the second line of
the display and is indicated by A - B.
