OBSERVED CONDITION CORRECTIVE ACTION
A. Analog Output 1 .Noise on input. Slowly turn
With No Flow SENS pot CCW until false in
dication stops.
NOTE: In fully CCW position
the unit will not operate.
D. Incorrect Analog 1 .Load resistance too small.
Output with Flow 2. Noise pickup present. Adjust
Sensitivity.
3. Calibration of FLSC-28
incorrect. Recalibrate.
E. Large Ripple on 1 .Wrong “Range” switch
Analog Output selected. Recalibrate.
2. Flowmeter being operated
below range. Adjust response
control to minimize ripple.
