I managed to do a successful load test from many trials with many batteries. code c.6 continued to exist, even with batteries over 12.5 volts. I tried to send it back but was disappointed with the return procedure. You must explain why you are not satisfied and then wait for an "RMA number". Then you have to explain again what the problem is and send two photos of the device and a photo of the receipt. You could not receive the photos I sent. After 3 attempts, my 7 days until shipping was up. I throw my Proseries PST-200 in the trash. Absolute waste of time and money.
