9 On-site adjustment
An on-site adjustment is carried out if an error has been confirmed due to certain on-site conditions after
the reasons according to section 13.1 have been checked. By changing the transducer constant K
simple adjustment can be performed.
Example:
Measurement condition Temperature must be relatively stable
Rho (measured density) = 996.6 Kg/m³
Rho (setpoint value)
difference (misalignment) = +0.6 Kg/m³
current K
value
0
setpoint K
misalignment
correct K
value
0
Now this value must be entered into the transmitter type TR.
If possible, the constants K
Depending on the operating mode or application and the reason for the error, the adjustment can also be
carried out via the concentration coefficient K
10 Configuration, operation
The transmitter can be configured (operated) in two different ways:
1. HART
2. On-site operation with keys and display
10.1 Operation via HART
The device can be operated using a PC or laptop and the SensorPort 2 configuration software in
connection with a HART
A HART
Communicator is another operating element which can be used (e.g. model HC-275 of
Rosemount). The operating functions of the HC-275 are defined in the HART "Device Description
Language" (DDL). Using the HC-275 the DIMF can be operated or configured on site. For the electrical
connection, see section 16.1.
