My powerlab 8 always read 0 ohms IR on cell 1 when chargine 6s.
But when i set the charging current to 1A, the IR is correct.
when i set the charging current to 5A, it read 0 ohms.
It doesn`t happen when charging 3s.
The firmware version is 3.33, and i am using the XH wiring.
I have an other powerlab 6 that show an IR of 3.x for the same packs on cell 1 using the same main leads and the balance leads.

Good Day,

Please check what wiring mode the charger is in. The PL8 will work in both wiring modes but the IR will only be accurate in the correct wiring mode for the way the pack is connected to the charger. Meaning which adapter you are using to connect the pack to the charger. Please refer to the owners manual to determine the correct wiring mode.
