To work with counters, the Edit counters access right is required.
On the General tab, apart from other properties, you can configure the mileage, engine hours and GPRS traffic counters.
In order for the engine hours and mileage by sensors to be calculated correctly, the device should send data with the required sensor parameters at least once every 100 messages.
You can select one of the following mileage calculation methods:
Calculation based on GPS coordinates (possible for any unit).
When calculating the mileage, an altitude value is not taken into account if the difference between this value and the one from the following message exceeds 500 meters.
|Calculation based on the mileage sensor.|
|Relative odometer||Calculation based on the Relative odometer sensor which counts the distance travelled since the last message.|
|GPS + engine ignition sensor||Calculation based on GPS coordinates and the readings of the ignition sensor.|
If a sensor (including a validation sensor) needs a parameter from the previous message, such a sensor cannot be used as a method of mileage calculation. The exception is the relative odometer.
The selected calculation method influences the data in reports (mileage, duration), tracks (mileage), and messages (distance). If the selected method is based on a sensor which is not configured for the unit, the mileage values are equal to zero.
Engine hours counter
The counter of engine hours calculates the working time based on the following sensors:
engine ignition sensor;
sensor of absolute engine hours;
sensor of relative engine hours.
The counter values are indicated in hours, therefore, you can use fractional values rounded to the nearest hundredths. Use a point as a separator.
If a sensor (including a validation sensor) needs a parameter from the previous message, such a sensor cannot be used as the method of calculating engine hours. The exception is the sensor of relative engine hours.
GPRS traffic counter
The GPRS traffic counter is designed to calculate the volume of the received and transmitted traffic.
To reset the counter, click Reset counter. Immediately after that, the system will suggest saving the sensor value in the unit history.
You can run the GPRS traffic report for this counter.
In the Current value field opposite each counter, you can specify the value from which mileage, engine hours or traffic should be calculated. Enable the Auto option to the right of the field in order for new data to be added to this value automatically.
The values of the counters are updated every 5 minutes.
To reset counter values manually, type 0 in the Current value field.
