Change of the display at different range of pressure sensor
(regardless of the measuring range of the pressure sensor, the pressure reference is necessary)
During the lifetime of the pressure sensor, the value of the range being nominally at 20,000 mA e.g., might be
shifted. This phenomenon could cause that the display shows a signal value which differs from the adjusted
boundary of the measuring range. In the control software of the display, this phenomenon was considered and
a function eliminating this phenomenon was implemented.
•
The PAof menu should be selected.
•
Both the buttons should simultaneously be pressed.
•
The number 0238 should be entered to select the special function.
•
Both the buttons should be pressed simultaneously again. The following sample value appears on the
display.
•
Now, the pressure sensor has to be pressurized via the pressure reference. The pressure has to
correspond to the ending value of the measuring range.
•
When pressing both the buttons simultaneously afterwards, the current output signal of the sensor is
saved as a voltage signal. From this moment, the adjusted ending of the measuring range (end-point)
appears on the display, although the sensor signal is shifted in the voltage signal.
ATTENTION: Please note that the output signal remains unaffected by this change.
Entering the data of the basic adjustment of the mechanism ("Load Defaults")
The control system of the display is equipped with the possibility to re-create the adjustment of the mechanism.
That way pre-made changes related to the compensation of the offset or the voltage can be performed
retroactively.
•
To load the basic adjustment, the PAof menu should be selected.
•
Then, both the buttons should simultaneously be pressed.
•
The number 0729 should be entered to select the special function.
•
Both the buttons should be pressed simultaneously again. The following sample value appears on the
display,
•
If both the buttons are simultaneously pressed again, the basic adjustment of the mechanism is
activated again.
Restrictions on entering a password
Dealing with special functions for the compensation of the offset, the range, recording the basic adjustment and
password change, various codes have been entered to call the function.
ATTENTION: Please note that these codes cannot be used as passwords.
