deviation is found, the reading can be corrected by adjusting the potentiometer. However, in case that a
remarkable deviation exists, the current output board is bad and needs to be changed.
When the 6105 gives correct current output at zero flowrate, the current output at various known
flowrates should be checked. Apply reference weights on the scale and press RUN key on the 6105
integrator to determine the flowrate at a percentage of the full load. For example, a belt scale with scale
capacity of 100t/h displays “ 10 ” , then the reference weight is 10% of the scale capacity. In this case the
milli-amperometer shall give a reading with the same percentage of the full scale. For this example, the
reading of the milli-amperometer shall be 16 (20-4)X10%+4mA = 5mA. If incorrect reading occurs, the
current output board should be repaired or changed.

Figure 6-4 Troubleshooting Current Output
Start
Check the current output. 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
