2 - Adjustments of the weight system. Option 2 of the main menu
The measuring of the weight is made through the electrical signals sent by a load cell located under the platform of the unit.
These signals are then converted and processed by the Main Board P1PC.
This chapter describes the steps to follow for a correct adjustment of the components associated to the weight system.
2.0 - Auto-zero or reset of the weight system.
Similarly to what happens to the height system, during the initial autotest the unit makes an auto-zero of the weight system.
With this option of the Advanced Programming Mode, this process can be made without having to switch the unit off and
on again.
When making an auto-zero of the weight system, the unit understands that there is nothing on the platform. The value of
the signal sent by the load cell at this moment is taken as the zero value (0 kg) of the weight system. This is why it is so
important to check that there is nothing on the platform before doing this process
.

Option 0 resets (autozero) the weight system. This process takes
about 5 seconds and it is very important to avoid the hits or sudden
movements or vibrations near the unit during this process.

When the process is finished, the program goes back to option 0 of
the weight adjustments sub-menu
SUB-MENU WEIGHT:
2.0-RESET

2.1 - Continuous weight measurement
This action allows you to make different measurements of weight and show them in the display.

The unit measures the weight continuously and shows the weight
of the current object/person on both the terminal and displays. On
the Terminal you can see 2 counters: The one on the right
measures in steps of 10 g, and the one on the left in steps of 100 g,
in the same way as the unit does during the normal measuring
preocess. The rests of countings concern the auto-zero system of
the unit.
