DL24 shows higher voltage when load is active

[cnrd]

Hi

I recently got a DL24 to test some cells, however I seem to have an odd issue, which I am not sure how to handle.

Whenever I turn on the load at 20A the voltage showed on the DL24 jumps up by about 0.6V, if I lower the current, the voltage also lowers.

When not discharging, the voltage seems to match the voltage of my multimeter.

I am using separate wires for discharging (10 AWG) and measuring (18AWG)

Am I doing something wrong here?

Thanks!

Same issue on the two I have.

I have two DL24s, no issues.
Maybe you got the connections wrong? Look at the bottom of the PCB, it shows where the current handling wires go (outer most if I recall correctly) and the voltage sensing (inner most, pos/neg).
