- Prior to site visit, determine how many amps the solar panel can push
- At site, set dial to 40 amps
- Toggle button mode to DC
- Clamp around black wire (in DC circuits, black is “hot”) and center vertically
- Press DC zero button
- If taken in full sun, reading should be at or near panel capacity (Ron, are there any hard numbers we could put in here?)
- Make sure to return dial to off position
