Gepruft IP 40 Insulation Tester

Gepruft IP 40 is an industrial insulation resistance tester used to measure dielectric integrity in motors, cables, and switchgear. Common failure modes include degraded high‑voltage isolation circuitry, damaged test leads or connectors, and internal power supply faults that cause erratic readings or no output. First‑check diagnostics: verify the unit’s 24 V (or specified) power supply with a multimeter; inspect all test lead connections for corrosion or breakage; and review any error codes displayed on the panel or via serial interface to isolate the fault source.[oss-gpt-20b]
