Safety Considerations

To measure voltages exceeding 1000V DC, ensure:

1. The circuit is isolated from the commercial power grid.
2. The circuit is isolated from the ground (e.g., when measuring the no-load voltage of an ungrounded solar panel).

⚠ Warning: Never use the clamp meter on circuits with a terminal-to-ground voltage exceeding 1000V, as this poses a risk of electric shock.
