Our internal tests set the voltage to 150V, arm the ChipSHOUTER, and then cycle through voltage settings.
However, there is occasionally a bug when you set to other voltage levels and arm the chipshouter causing a fault to occur. This occurs because we don't wait long enough before checking if the HV charge is working OK. This will be fixed in a future firmware version.
For now if you see the charge error, simply change your set voltage to a lower voltage (150V), Arm the chipshouter, then set final voltage. If this still gives you error try a different voltage as the initial setting until you find one that reliably arms, and use that for your initial voltage.
