Re: [EFLT] Robbe IR Meter - was: Internal resistance
This message from "Red Scholefield" <firstname.lastname@example.org> brought to you by EFLIGHT!
The Robbe meter measures the AC Impedance, NOT the internal resistance.
There is a significant difference.
>From the web site mentioned:
Measurement range: 1 ... 30 cells, max. 50 V
Measurement freq.: approx. 1 kHz
Power supply: Internal: 2 x 9 V batteries
External: 9 V stabilised
mains PSU, or
8-cell NC battery,
e.g. transmitter battery
While there is some broad corrolation the AC Impeadance is quite meaningless
in the electric flight application.
