11.5 Current output
In Diagnostics menu press
5 Current output
.
mA-looptest: 1, 2:
Select Looptest Output1/
Output2.
Looptest locks the output signal to 4 mA, 20 mA, hold (present) value, or some other
user-defined value. It can be used to check the cabling and current output circuits.
•
Output1/2:
When this display is activated,
the analog output is frozen to its present
value, shown here.
•
1:
Set the analog output1/2 to 4 mA.
•
2:
Set the analog output1/2 to 20 mA.
•
Up/Down:
Increase/decrease the analog
output value with the Up/Down keys.
Trim mA: 1, 2:
Select "Trim Output1/Output2".
This function requires that you connect an ammeter to the analog output. The device
will first send a 4 mA signal to the analog output. Measure the actual current value and
enter it to the device by changing the "Actual" value.
•
Output1/2:
The analog output is frozen to
its present value, shown here.
•
Actual:
Enter the measured value in the
Edit mode.
•
Enter:
Accept the value.
The device then sends a 20 mA signal to the
analog output. Measure the actual current val-
ue and change it in the same way as for the 4
mA signal.
