An alternative calibration option is calibration without fuel. | |||
In this case, make sure that the sensor tubes are empty and free of fuel, but the centralizer must be inserted into the tubes. Leave the '''"Calibrate without fuel"''' switch ('''1''') active ('''green''') and press '''"Calibrate"''' ('''2''') . The values above the Empty and Full buttons will change automatically. | |||

If you calibrate the sensor without fuel, the operating range may change slightly. | |||
Initially there are two measurement ranges: | |||
* From 1 to1023 | |||
* From 1 to 4095 | |||
The sensor never sends a value of 0. If there is no fuel, level 1 is displayed. | |||
'''When calibrating without fuel, since the sensor does not know what fuel will be used, the "Empty" value is set based on the current (CNT), the "Full" value is set by a formula and, depending on the length of the tubes and the final fuel used, the range may change .''' | |||
''' | '''For example, when the tank is full, the sensor will show 3843 instead of 4095, or it is possible that when the tank is 98% full, the sensor will already display the value 4095.''' | ||
''' | '''We recommend, if possible, calibration with fuel.''' | ||

We do not recommend using this functionality, but you can set the Full and Empty calibration values manually to save time when you are using sensors of the same length in the same tanks.<blockquote>'''<big>Attention!!! Setting calibration values manually will most likely increase the sensor error! We do not recommend doing this!</big>'''</blockquote>To do this, enter the Full and Empty calibration values of the previously calibrated sensor into the appropriate fields in the configurator. | |||

In the main menu, you can change the operating mode of the sensor. The name of the mode coincides with the interface that is used to physically connect the sensor to the GPS terminal | |||
Select the mode you need('''1''') and click '''“Save parameters to device”'''('''2''') | |||

If you are configuring the sensor to operate in RS-485, Active RS-485, or Frequency modes, you can select the range '''1-1023 or 1-4095''' ('''1''') . In frequency mode, the range will be from '''300Hz to 1323Hz or 300Hz to 4395Hz'''. | |||
After changing the range, click “'''Save the parameters to device'''” ('''2'''). | |||

''' | '''The range 1-1023''' is most often used for sensors that are '''shorter than 1 meter'''. However, if we are talking about a stationary tank, the height of which is small, but the length and width are more than 2-3 m, it is better to choose the range 1-4095. | ||

The default network address of the sensor is 1; if more than one unit is installed or other LLS devices are added, the network address on the sensor may need to be changed. The network address of each sensor must also be specified in the settings of the receiving device (navigation terminal).<blockquote>'''<big>Attention!!! There cannot be two devices with the same network address on the same line; this will cause a conflict.</big>'''</blockquote>To change the network address, enter a new address in the range '''0-255''' in the '''“Change network address”''' field ('''1''') and click '''“Save the parameters to device”''' ('''2'''), after which the configurator should switch to the new sensor address and display the new sensor address in the field '''"Available units"''' ('''3''') and '''"Poll network address"''' ('''4'''). | |||

Once the length sensor has been adjusted to the height of the tank and the sensor has been calibrated, you need to install it in the tank. | |||
Install the sensor into the tank of the installed tube in the previously drilled hole ø 30-35 mm. Make sure '''the gasket is installed''' between the sensor and the tank. After this, screw the screws from the installation kit into the previously drilled ø 3mm holes.<gallery widths="700" heights="400"> | |||

</gallery> | </gallery>Proceed to tank calibration. This procedure will result in a "level-liters" (or "level-gallons") table that will allow your monitoring platform to convert the level values that the sensor provides into liters/gallons that are displayed in the monitoring platform reports. | ||
In order to create such a table, you need to fill the tank by step by step adding fuel to the tank batch by batch and recording level-liter(/gallon) pairs after each batch using the Tare menu in the application. | |||
Suppose you need to tare a 100L tank in ten 10L portions. | |||
To do this you should: | |||
