Calibrating

Locking Calibration Settings

The generator uses an internal hardware jumper to enable and disable changes to calibration

settings. If the Options > Calibration option is available, the jumper is set to enable re-calibration.

To prevent users from changing calibration settings:

1. Turn the generator off, and remove the back cover.

2. Locate the J10 jumper, which is near the lower-right corner of the board.

3. Connect the jumper to only one pin to disable user calibration. Connect both bins to enable

user calibration.

4. Install the back cover.
