8.1 System Warning Message(s)
Automatic warning messages are generated by the OCM to provide you with specific
diagnostic information about the instrument. These are only messages and they do not
indicate failure of any component in the instrument. The following table lists the warning
messages and their associated meanings:

is an internal failure.
W03 Analog Loop Failure The 4-20mA is activated and the loop
is open.
W05 Water used for 0 ADJ is too
cloudy

be too cloudy for the instrument to
operate properly. Replace water and
calibrate again.
O-r Sample Over-Range The sample presented to the OCM is
over 50 PPM.
