Creating Log Files of Inputs
The PC software can create a text file of the live data
stream from the payload meter. This can be very use-
ful for diagnostic purposes. The data is written into a
text data file in comma separated value format. The
data is recorded in metric units at 50 samples per
second. The data file can grow large very quickly.
Each sample writes one line into the ASCII file in
comma separated format.
The order for each line of data in is:
• Date
• Time
• Sprung Weight
• LF Pressure
• RF Pressure
• LR Pressure
• RR Pressure
• Incline
• Speed
• Body Up State (1=up)
• Brake Lock State (1=on)
• Payload State
• Status Flags
• Spare
To create a log file:
1. Connect to the payload meter and start the PC
software.
2. From the main menu, select "Connect to Pay-
load Meter". The PC will request the latest sta-
tus information from the payload meter.
3. Select the "Real Time Data" button. The real
time data screen will pop up. The PC will
request the payload meter to begin transmitting
data.
4. Click the "Set File Name" button and enter a
name and location for the text file. The default
extension is ".txt". This data can be easily
imported into spreadsheets as a comma sepa-
rated value (.CSV) format.
5. Once the filename has been entered, the Start
Log and Stop Log buttons will be active.
6. Press the "Start Log" button to start taking data
and recording into the file. Once a file is started,
it cannot be stopped and started again.
7. Press the "Stop Log" button to stop recording
data. Attempting to start the log file again will
overwrite the previous file and erase the previ-
ous data. To gather more data, close the real
time data window, start it again and create a
new log file.

Daily Inspections
An important part of maintaining the Payload Meter
III (PLMIII) system is monitoring the basic inputs to
the system. It is recommended that the truck opera-
tor walk around the truck and visually inspect the fol-
lowing:
• Charging condition of the suspensions - not flat,
not overcharged.
• Pressures
suspensions by using the operator gauge and the
operator switch.
Periodic Maintenance
It is recommended that the following items be
checked every 500 hours:
• Confirm the suspension pressures using external
gauges.
• Confirm proper suspension height.
• Confirm suspensions do not collapse and make
metal-to-metal contact when the truck is loaded.
• Confirm that inclinometer indicates positive (+)
values for truck nose up, and negative (-) values
for truck nose down.
In addition, it may be useful to confirm proper opera-
tion of the suspensions by riding the truck during a
complete haul cycle. Record the suspension pres-
sures using the CSV log file tool in the Payload Data
Manager software for the PC. The suspension pres-
sures in this log file can be graphed to inspect for flat
or overcharged suspensions.
