Clean Truck Tare
The payload meter uses the clean truck tare value to
calculate carry-back load for each haul cycle. The
carry-back stored in the haul cycle record is the new
empty tare minus the clean truck tare.
This procedure should be performed after service to
the suspensions or when significant changes are
made to the sprung weight of the truck. Before per-
forming this procedure, be sure the suspensions are
properly filled with oil and charged. It is critical to pay-
load measurement that the proper oil height and gas
pressure be used.
Once the clean tare process is started, the payload
meter will begin to calculate the clean empty sprung
weight of the truck. This calculation continues while
the truck drives to the next loading site. Once the
procedure is started, there is no reason to continue
to monitor the process with the PC. The truck does
not need to be moving to start this procedure.
1. After cleaning debris from the truck and check-
ing to see that the suspensions are properly
serviced, use the PLMIII software to connect to
the payload meter.
2. From the "Truck Configuration" screen, select
"Clean Truck Tare".
3. Be sure to follow the screen instructions.

Inclinometer Calibration
The inclinometer calibration procedure is designed to
compensate for variations in the mounting attitude of
the inclinometer. The inclinometer input is critical to
the payload calculation.
This procedure should be performed on relatively flat
ground. Often the maintenance area is an ideal loca-
tion for this procedure.
1. After cleaning debris from the truck and check-
ing to see that the suspensions are properly
serviced, use the PLMIII software to connect to
the payload meter.
2. From the "Truck Configuration" screen, select
"Inclinometer".
3. With the truck stopped and the brake lock on,
press the "Start" button. This instructs the pay-
load meter to sample the inclinometer once.
4. Turn the truck around. Drive the truck around
and park in the exact same spot as before, fac-
ing the other direction.
5. With the truck stopped and the brake lock on,
press the "Start" button. This instructs the pay-
load meter to sample the inclinometer again.
The payload meter will average the two sam-
ples to determine the average offset.
6. Be sure to follow the screen instructions.
