Figure 4- 4 Troubleshooting Current Output
Start
Connect power supply to the system. Run the belt empty at the normal speed, the
flowrate indication should be zero. Remove the connections on the signal output
terminals which are then connected to a milli-amperometer.
Check the flowrate indication at current output of 4mA, which should be zero.
Otherwise, perform zero calibration.
The reading of milli-amperometer should be 4mA
The current output is normal – 4mA
Check the current output at a known flowrate. Apply reference weights on the scale
and press RUN key to determine the flowrate at a percentage of the scale capacity.
Check the milli-amperometer gives a reading
with the same percentage
The current output baord functions well
