Set Analog Output Error Notification

If the transmitter is malfunctioning, the analog output is set to a pre-

defined level of 3.8 mA. This overrides the normal measurement output

of the channel. You can change the level, or disable this behavior, using

the

AERR command:

AERR [on/off] [level]<cr>

where

on/off = Enable (on) or disable (off) the analog output error

notification.

level = Analog output level, range 3.5 ... 30 mA.

Example (show current settings):

>aerr

Notification : ON

Error level 4-20 mA (mA): 3.800000

Example (disable analog output error notification):

>aerr off

>Notification : OFF

Saving settings...done

Example (enable analog output error notification, set level to 21 mA):

>aerr on 21

Error level 4-20 mA (mA): 21.000000

Saving settings...done

NOTE

The error output value is displayed only when there are minor electrical

faults such as a humidity sensor damage. When there is a severe device

malfunction, the error output value is not necessarily shown.
