5.2.1.3 Output signal during errors
When an error condition occurs, a 22 mA output signal can be sent as
a notification (default: off).
5.2.1.4 Output signal during HOLD
The output signal during hold periods can be maintained at the last
measured value (
Figure 12 ) or fixed at a specified value ( Figure 13 ).
The allowable range for the fixed value is 3.4 to 22 mA.
