Output is 0 mA. Cable is open-circuited.
Output is over 20 mA. "OVERFLOW" is indicated on LCD. Range over.
z
Recheck and set range data of
analog output.
Output is below 4 mA. "UNDERFLOW" is indicated on
LCD. Back flow
z
Set the upstream and downstream
properly.
Measurement value
varies but analog output
is constant. Output load is above 600 :. z Lower the load below 600 :.
Analog output does not
