6.1 Measurement with ISDS sensors
How to perform measurements
1 Find the MINIMESS testing point on your hydrau-
lic system.
Remove the protective caps from the MINIMESS
testing points you want to use to make measure-
ments.
2 Connect the ISDS sensors to the measuring in-
strument with the instrument switched off.
3 Connect the ISDS sensors with the MINIMESS di-
rect connections.
If necessary, remove the protective plastic cover-
ing from the MINIMESS direct connections.
Only tighten the thread manually. Do not use a
tool.
4 Connect the MINIMESS direct connections of the
ISDS sensors to the selected MINIMESS testing
points.
5 Switch the measuring instrument on by pressing
[F4]
.
If applicable, use
[F4]
to confirm the calibration
notice.
The ISDS sensors are detected by the measuring
instrument. The display shows the current meas-
urement values.
p1
displays the measurement value of the sensor
from channel 1 (
CH1
). Measurement unit
[bar]
follows.
p2
stands for channel 2 (
CH2
).
dp
(special channel) shows the difference be-
tween
p1
and
p2
.
Zero adjustment
Press
[F2]
to execute a zero adjustment. The current
measurement values are set to zero.
Observe the following rules:
•
Zero adjustment is applied to all displayed chan-
nels.
• Zero adjustment cannot be undone.
• Zero adjustment is only deactivated when you
switch off the measuring instrument.
• For safety reasons, a zero adjustment can only be
executed up to values of 1% of the maximum
measurement range.
With larger values, the display shows code
8110
and the maximum permissible values.
• A zero adjustment cannot be executed for chan-
nels showing a frequency.
• Measurement values are set to zero for channels
configured as counters.
