Frsky FLD-02, A1 value help...

Hi Guys,

I'm a little bit confused here and I need your help. I do have:

Frsky FLD-02 with soft 2.1
Frsky FBVS-01 sensor
Frsky DJT Module
Trying to put everything together with 4 cell 14.8 LiPo.

A1 - Jumper from x to A1
A2 - Cable from FBVS-01, I cut the ground

A1 - Volt Ratio 4
A2 - Volt Ratio 6

FLD-02 Values:
A1 (Left Value) - 5.2
A2 (Right Value) - 15.9

I know A2 looks right, but what is A1? What is that A1value telling me?

Thanks a lot

The A1 value tells you the voltage supplied to you receiver (cause you're using the jumper) and I guess this is a ESC bec with a quite common 5.2v (mine is same).

You should read the receiver manual, even if it's not easy, there is good informations about features...

Yes, when A1 is jumpered, it measures internal receiver voltage (BEC)
If you need to measure two separate external voltages, for example a second pack, remove the jumper and install a second FBVS-01 sensor, setting the ratio accordingly.
