Devices that are not turned down prior to delivery are trimmed at 0 bar and the upper limit of
the nominal range; devices that are turned down prior to delivery are trimmed at the lower
and upper limits of the set pressure measuring range.
Note
The accuracy of the test device should be at least three times as high as that of the pressure
transmitter.
6.3.9.2
Trimming the sensor
Trim the sensor at the lower trim point
The pressure at which the lower sensor trim is to be performed is applied at the pressure
transmitter. Via SIMATIC PDM or the HART Communicator, you instruct the pressure
transmitter to accept this pressure.
This represents an offset shift of the characteristic curve.
Trim the sensor at the upper trim point
The pressure at which the upper sensor trim is to be performed is applied at the pressure
transmitter. Via SIMATIC PDM or the HART Communicator, you instruct the pressure
transmitter to accept this pressure.
A gradient correction is thereby applied to the characteristic curve. The lower sensor trim
point is not affected by this. The upper trim point needs to be greater than the lower trim
point.
