Once the sensor’s menu is open, you can see its current readings. Tap on the '''Calibrate''' button to open the '''calibration menu'''. | Once the sensor’s menu is open, you can see its current readings. Tap on the '''Calibrate''' button to open the '''calibration menu'''. | ||

Next, press the '''+''' button. Then enter the Pressure reading (from the screen with the Sensor’s data) and Weight reading (from the scales) and tap '''Enter'''. | |||
To edit the table, '''press and hold''' one of its lines then either add one more line, change the selected one or delete it. | |||
After the table is finished tap on the '''Save button'''. Repeat the procedure of weighing and setting the table for every sensor. | |||
You can add more than '''2 lines''' should you have the possibility to weigh every axis while the load in the semi trailer is different but '''2 lines''' will do in most cases. The max number of lines - '''20'''. | |||

== '''<big>RS-485 settings</big>''' == | |||
To enable the transmission of the data the central unit receives from the Sensors paired with it via Bluetooth to a GPS tracker/gateway by means of the '''RS-485''' interface, connect the central unit and open the '''RS-485''' settings menu. Select one of the paired Sensors there. | |||
[[File:Imagevzxccw.png|center|frameless|648x648px]] | |||
Then select the pair of parameters you need transmitted and enable it. After that select the network address that will be used for the transmission of that pair from the central unit to the GPS tracker/gateway. | |||

'''<big>ATTENTION! Ensure that every pair of parameters in every Sensor’s menu is assigned a unique network address. If you have several other wired sensors connected to the same GPS tracker/gateway via the RS-485 interface, remember that they also already occupy one or several network addresses so you need to avoid assigning the central unit any of those network address.</big>''' | |||
For example, if there’s a wired FLS that had been assigned the network '''address 1''', the address 1 '''cannot be''' assigned to the '''central unit'''. | |||
Note that the app could be reading “'''All network addresses are free'''” but the app cannot check if there any other wired sensors connected to your tracker/gateway. It only checks what network addresses had been assigned to every paired Sensor in the central unit’s configuration. | |||
== '''<big>Data view</big>''' == | |||
You, your customer or the truck’s driver can access the '''current readings''' transmitted by the Sensors '''via the app'''. | |||
Connect the '''central unit'''. | |||
[[File:Imagegrgt4353.png|center|frameless|656x656px]] | |||
Then tap '''View data'''. On the next screen the app will show the readings of all Sensors paired with the central unit. | |||

'''ATTENTION! When selecting the spot at which to install the central unit, be sure to check if the average RSSI of every sensor as measured within 2-3 minutes is within the -35 dBm to -100 dBm range. If it is not, try moving the central unit closer to the sensors to minimize the risks of connection losses in future!''' | |||
== '''<big>How many sensors are required?</big>''' == | |||
The general recommendation is to install '''as many as sensors as many axes the vehicle has'''. In other words: '''1 axis = 1 sensor'''. | |||
It is possible that in some cases, '''one sensor''' could be used to monitor the load on several axes provided that the air springs that support those axes are united into '''one suspension circuit'''. | |||
'''<big>The following are a few examples of possible installation of several sensors:</big>''' | |||
[[File:Imagedsd13.png|center|frameless|594x594px]] | |||
A and B are possible slots where the 2 sensors would have to be installed to monitor the load of every axis | |||
[[File:Imageg546345.png|center|frameless|640x640px]] | |||
In this case it is possible that only one sensor could be installed either at point A or B. | |||
However, you would need to be collecting the pressure readings of the sensor and have 2 virtual sensors on your monitoring platform (the calibration tables would have to be saved and applied in those virtual sensors). | |||

[[File:Image1241а13.png|center|frameless|669x669px]] | |||
In this case either 6 or 3 sensors could be installed (1 or 2 per axis) to monitor the axle load. | |||
It is still possible that the load distributed between the two out of three axes could be more or less equal and therefore 1 or 2 sensors could be enough. | |||
However, if one of the axes is a liftable one, installing one sensor on it is obligatory. | |||
== '''<big>Configuration of virtual sensor for steering (spring) axle</big>''' == | |||
To calculate a '''total weight of a semi-trailer truck''' it’s necessary to weigh both the '''steering and the rear axis of a truck''' ('''dump truck''') without a '''semi-trailer''' (if '''dump truck''', without a '''cargo'''). If there are several front and\or rear axles, it’s necessary to '''weigh each'''. | |||
Next, in the Sensor configuration menu, press '''+''' the button and select the '''Add the head axle''' option. | |||
