9.0.3 Wire resistance measurement page
Description
C1 uses the differential pressure method to measure the internal resistance of the
cable, which needs to be used with a constant current load.
Instructions
Click the OK button: use the current voltage and current value as the reference value.
Measurement procedure
(1) Connection method: charger + C1 + constant current load (the current is
adjusted to about 0.5-1A), and record the reference value.
(2) Connection method: charger + cable + C1 + constant current load (the current is
adjusted to about 0.5-1A, and it needs to be followed
The current when recording the reference value is similar), the system automatically
calculates the internal resistance of the cable.
