NOTICE
Current trimming does not affect the digital HART
®
value. This can cause the
measured value shown on the display to differ marginally from the value displayed in
the higher-level system.
‣
The digital measured values can be adapted with the sensor trimming parameter in the
menu Expert → Sensor → Sensor trimming.
Procedure
1. Start
ß
2. Install an accurate ammeter (more accurate than the transmitter) in the current loop.
ß
3. Switch on current output simulation and set the simulation value to 4 mA.
ß
4. Measure the loop current with the ammeter and make a note of the value.
ß
5. Set the simulation value to 20 mA.
ß
6. Measure the loop current with the ammeter and make a note of the value.
ß
7. Enter the current values determined as adjustment values in the Current trimming 4 mA / 20 mA
parameters
ß
8. End
