Refer to Figure 6-4 Current Output Diagnostics Flow Chart, check the flowrate at different current
output ranging from 4mA to 20mA (full range) at a certain interval. In order to check the flowrate at 4mA
current output, power up the 6105 and run the belt empty. If the flowrate indication is not zero, reset it
by performing zero calibration. Remove the connections from the current output terminals which are
then connected to the DC milli-amperometer correctly (Note that the range of milli-amperometer should
exceed 20mA). At this time the current output on the milli-amperometer should be 4mA. If a minor
Start
Check load cell input, Power on the
6105 and enter Diagnostics menu
The load indication is between 1 and
16777216, and increases as the
actual load increases
No load cell input
Check load cell and wire conntection
Repair and replace
Load cell input is
normal

The excitation voltage on the load
cell should be DC 9.5 to 10.5V
The voltage between signal leads of
the load cell should be lower than 30mV
