Port Specific Status Information
There is one byte within the Total Consumption reading (present or frozen) which
contains data that may be invaluable for diagnosing and troubleshooting issues
prior to rolling a truck.
Total Consumption (TC) registers (Present and Frozen Daily) on the EMTR-3
contain a three byte TC value and a one byte TC status. The Hour of Reading and
Configuration field in the TC status is used to establish a desired level of validity
for the TC reading. This five bit field also serves as a quick alternate method for
time stamping the data.
The Master Station (MS) has the capability to decide the quality of a TC reading
based on the Hour of Reading and Configuration field in the status byte of the
Total Consumption registers. TNS reflects the status of the TC reading in the TNS
field of the MIT On Request window.
Use the following procedure to access the MIT On Request window.
1. Follow the menu path Start > All Programs > TNS Metering Maintenance
> TNS Metering Maintenance to view the Metering Maintenance toolbar.
