CALIBRATION:
Pressure/Force values are continuously transmitted for display if the CALIBRATION button
is activated. Proceed as follows for two-point calibration:
•
Resolution setting = 1 and offset = 0 (direct display of sensor output voltage) and
activation of calibration
•
Record 2 measuring points with 2 calibrated reference densities, note reference
density and sensor voltage
•
Calculate resolution and offset with following formula:
Resolution = (F2-F1)/(U2-U1)
Offset = F1-(resolution · U1)
•
Set resolution and offset and deactivate calibration again:
U1,2 ...sensor voltage 1 and 2, F1,2 force value of reference densities (g =
9.81m/s²)

Determining Limit Values
Preparations
•
Select button MENU with the
knob/pushbutton combination and depress
button.
•
Select button LIMITS with the
knob/pushbutton combination and depress
button.
•
Screen LIMITS opens, and now you may
perform all necessary settings.
Notes
•
You can determine maximum two values to
be monitored per channel.
•
Evaluation of the limit values after each
measurement.
The evaluation result is:
-
displayed by the LEDs on the
equipment front page,
-
logged, and
-
made available by the digital output at
the equipment rear side.
•
The evaluation result is formed by a logical
OR link if both channels are monitored and
the measurement occurs simultaneously.
Defining limits
MAX LIM, MAX WARN, MIN WARN,
MIN LIM
Here you determine the limits for the minimum
or maximum warning and limit value.
Limit value monitoring is deactivated if the min.
and max. limit are set at zero. The same
applies to warning limits.
