6.0.5 Wire resistance measurement page
Description
FNB48 uses the differential pressure method to measure the internal resistance of the
cable, which needs to be used with a constant current load.
(1) Click the middle button: use the current voltage and current
value as the reference value
Measurement procedure
(1) Connection mode: charger + FNB48 + constant current load (the
current is adjusted to about 0.5-1A), and record the reference
value.
(2) Connection method: charger + cable + FNB48 + constant current
load (the current is adjusted to about 0.5-1A, which needs to be
similar to the current when the reference value is recorded),
the system automatically calculates the internal resistance of
the cable
