How to choose an electrical safety tester
Start with your standard: hipot (AC/DC withstand), insulation resistance, or earth continuity. Then confirm required ranges, dwell time, and automation I/O (USB/RS232/Handler) for your line. Unsure which fits? Pick the instrument that covers your highest test voltage/current with margin.
