Digital Sensor Trim Via The Krohne Dtm - KROHNE OPTIBAR PM 5060 C Manuel De Référence

OPTIBAR PM 5060 C
Reset of the digital sensor trim (SP04)
Special parameter SP04 resets the zero point and span trim back to factory settings. Attention: If
a reset to factory settings is carried out, the previously set trim values are retained! A reset to
the basic settings, resets the trim values to the original factory settings.

6.9.2 Digital sensor trim via the KROHNE DTM

The digital sensor trim can be carried out via PACTware
Therefore, the sensor needs to be connected to the terminal instrument via a suitable interface.
To get to the appropriate menu items, the following steps needs to be carried out: Menu ->
Parameter -> Parameterisation Parameter -> Parameterisation.
Parameter -> Parameterisation Parameter -> Parameterisation
Before the digital sensor trim can be performed, an active offset correction needs to be reset.
Therefore, the value of the sensor mounting corrections needs to be set to 0 manually via: Setup
-> Sensor mounting correction. Via the Apply -> Sensor mounting correction
-> Sensor mounting correction -> Sensor mounting correction
After the digital sensor trim has been performed, the effect of mounting position can be
corrected again via the automatic sensor mounting correction.
To get access to the special parameters, the service login needs to be activated. Therefore,

system is completely depressurised. The currently applied pressure is set as the new zero point
(LRV) and assigned to the current output value of 4 mA. The characteristic curve is adjusted on
one side during this procedure, so that the end of the measuring range (URV) remains
unaffected. To finally complete the configuration, the parameterisation needs to be written into
the instrument using the Apply

applied pressure reference corresponds to the desired end of the measuring range (URV). The
currently applied pressure is set as the new measuring span (URV) and assigned to the current
output value of 20 mA. The characteristic curve is adjusted on one side during this procedure so
that the lower range value (LRV) remains unaffected. To finally complete the configuration, the
parameterisation needs to be written into the instrument using the Apply
