This device does not seem to comply with specifications. It does not read all the time. In my case, most of the time it indicates Err instead of cell voltages. I use it LTO cells, the spec says it should read cell voltages between 0 and 5Vdc. I don't know how to fix this situation and the supplier is of no assistance. I have a feeling the supplier is a box mover and has no clue how this device should work, so this supplier is unable to help me. I have the impression this product has a software problem. Otherwise this product comes well packaged and presented. If it's available, I would welcome help from the manufacturer in solving this "Err" problem.

Q: I just received the SK500007 device. When I connect it, shows "err" 5 times instead of the 5 cell voltages. There are no instructions on how to connect for a 5s setup. I checked the voltage at each pin with a multimeter, all seems normal. I know the voltage is low, around 2.5 volts, it's fine for LTO cells (1.7 to 2.8 volts). The specs say the voltmeters can read from 0 to 5 volts. Is this device defective? Is there a way to change this "err" behaviour?
