B.5
Analog output
B.5.1 The 4-20 mA output is wrong
Reason
Solution
Analog output settings incorrect.
1. Check analog output settings.
2. Run
Simulate current output
and verify the
correct output.
Sensor and data acquisition system have dif-
ferent grounds.
Verify that sensor and data acquisition system
have the same ground.
The 4-20 mA output is delayed by approx. 150
ms. If the output is read before, a wrong value
is acquired.
Sample the 4-20 mA output with a delay of more
than 150 ms.
