mA output signal during system error
This function determines how the mA output should act in
case of a system error.
System errors are most often caused by a weak or missing
ultrasonic echo, but may also occur by failure of the ultra-
sonic sensor or failure in Shuttle
® 's internal circuits.
Select the desired condition with the arrow keys.
The mA output will be locked on the last known value when
a system error occurs.
The mA output will give a fixed signal when a system error
occurs.
Select the desired value (0.35 to 20.5 mA) of the fixed signal
with the arrow keys.
