Table 5-2 Operation Errors
Symptom Check Points and Treatment
Output uctuates
excessively beyond the
estimated ow rate range.
• Verify that the detector is properly grounded.
• Verify that the converter is properly grounded.
• Verify that the damping time constant is set
correctly. If not, set the an appropriate damping
time constant.
• Clean the electrodes.
Flow rate exceeds the ow
range
• Check the ow range setting and make sure it is set
to match the detector and process ow. If not, set
an appropriate RANGE.
• Check that the owmeter has been zeroed. If not,
calibrate the owmeter.
Output exceeds 100%.
• Verify that the set range is set correctly.
• Verify that the span is set correctly.
• Verify that the zero point is correctly adjusted.
• Verify that the converter is correctly calibrated.
Output remains 0%.
• The pipe may be empty. Use the empty detection
function to check whether or not the pipe is empty.
(If it is empty, the empty detection function will be
functioning.)
• Verify that the signal cable is correctly connected.
• Verify that the valves are open on the upper and
lower sides.
• Verify that the span is set correctly.
• Verify that the converter is set to the constant
current mode.
• Verify that the ow rate is not in the low ow
cuto range.
Output is in the fail-safe
mode.
• Check the error code.
Pulse output is too large or
too small.
• Verify if the pulse weight and width are set
correctly.
• Verify the converter is correctly calibrated.
• Verify the pulse counter is proper.
• Verify the dropout value is correctly set between 0
and 10%.
