Using Scope Monitoring Inputs Using Scope 1. Install Scope to a laptop and connect to the payload meter using the EF9160 download harness. 2. Verify that the serial port on the laptop is available. Some programs for monitoring Palm Pilots, Pocket PC’s, etc. control the serial port and will prevent Scope from working. 3. Start Scope. The program will confirm proper setup and access the serial port. If there is no confirmation of proper setup, verify that the applicable Scope program is being used. Scope.exe is for laptops using Comm1 for serial communications. Scopeforcomm2.exe is for laptops using Comm2 for serial communications. In almost all cases, Scope.exe is the correct program to use.
4. Select " StartRTM " from the menu bar on the top of the screen to begin a real-time display of payload meter inputs and status. 5. At the bottom right of the screen line "RTM D I/O= n b e r" will appear. The four letters are the status of the four digital inputs. N=brake lock, B=body up, E=engine run, R=R terminal. Refer to Table 1. These status indica- tors are 'live'. Turning the brake lock ON or OFF should change the capitalization of the letter N; "N"=brake lock ON, "n"=brake lock off. 6. Above the digital input status line is "RTM Status". This line is the payload or truck 'state'. If the truck is empty and stopped, the status will be "01" (Empty Stop). Refer to Table 2. 7.
All the "RTM" status lines indicate real-time status for that input. The pressures, incline, and speed are all 'live' and will change as the truck moves or changes condition. 8. Confirm that the payload meter properly receives all the inputs. 9. Select " StopRTM " from the menu bar to stop the data transmission from payload meter.

Some programs for monitoring Palm Pilots, Pocket PC’s, etc. control the serial port and will prevent Scope from working. 3. Start Scope.
The program will confirm proper setup and access to the serial port. If not, be sure you are using the applicable scope program. Scope.exe is for laptops using Comm1 for serial communications. Scopeforcomm2.exe is for laptops using Comm2 for serial communications. In almost all cases, Scope.exe is the correct program to use. 4. Select " StartRTM " from the menu bar on the top of the screen to begin a real-time display of payload meter inputs and status. 5. Select " StartLog " from the menu bar. The program will prompt you for a file location and file name. Store the file on your hard drive in a place where you will be able to find it later.
It is best to create a new folder on the Windows desktop to store log files from tests. 6. Enter a file name with a ".csv" extension. For example, on truck 214 one might enter "T214.CSV" as a file name. The ".CSV" at the end will make it easier for Excel or Lotus 123 to recognize the file format, Comma Separated Variable, and open it properly. 7. The Scope program will write each real-time data message from the payload meter into the log file. These messages come 5 times each second. 8. Run the truck through an entire haul cycle. 9. Stop the log file as the truck begins to drive away from the dump by selecting " StopLog " from the menu at the top of the screen. 10.
Stop real-time communications by selecting " StopRTM " from the menu bar. M20007.2 3/02 Payload Meter II™ Troubleshooting M20-61
