AERR
Example:
>aerr
Ch1 error out : 0.000V ? 5.0
Ch2 error out : 0.000V ? 5.0
>
NOTE
The error output value must be within a valid range for the output
type.
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.
Relay Operation
Quantity for Relay Output
A relay monitors the quantity chosen for the relay output. Any of the
quantities available can be chosen.
Relay Setpoints
When the measured value is in between the "above" and "below"
values, the relay is passive. When choosing lower value as "above"
value and higher value as "below" value, the relay is passive when the
measured value is not between the setpoints.
You can also set only one setpoint.
