For Input signal you can choose between
HSI (HYDAC Sensor Interface) and various
standard analogue signals in the drop-down
list (using the arrow keys). To set the Lower
and Upper measurement range, enter the
relevant limits via the combination keypad.
A drop-down list is also provided for
selecting the Unit (of measurement). You
also have the option of defining your own
unit with other (top line of the drop-down
list). The cursor then jumps to the input
box and a small triangular arrow appears
as the insertion point. Enter the new unit
using the combination keypad, e.g. ”kPa”
for kilopascal.
To enter additional characters, move the
triangle insertion point to the desired posi-
tion and enter the characters. Confirm your
entry with OK so that your unit of meas-
urement is stored.
Decimal format: Here you can specify how
many decimal places are to be used when
recording and displaying the measured val-
ues.
In addition to the settings described above,
Channel B has two further measurement
options. In the Mode drop-down menu you
now also have the menu options Pressure
difference dP and Orifice measurement
Q=f(dP). With Pressure difference dP the
HMG 3010 gives you the opportunity to dis-
play the difference in pressure between
channel A – channel B with a very high de-
gree of accuracy. This can be used, for ex-
ample, to determine if a filter is clogged, by
measuring the pressure differential.
