Megger MOM690 Micro-ohmmeter

Megger MOM690 Micro-ohmmeter — High-Current AC/DC Contact Resistance Testing

The Megger MOM690 is a high-current micro-ohmmeter that delivers up to 800 A of AC or DC test current for demanding contact and joint resistance measurement. Measuring 0–200 mΩ with microhm resolution and ±1% accuracy, and with both AC and DC output capability, it is ideal for substations and heavy industry where high test currents or AC testing are required.

Key Features

• Up to 800 A output — automatic-range test current for large high-current connections.
• AC or DC testing — selectable AC and DC outputs for different test requirements.
• Microhm resolution — measures 0–200 mΩ with 1 µΩ resolution.
• High accuracy — ±1% of reading ±1 digit at 100–800 A.
• Clear digital display — shows resistance/voltage, current value and function mode.
• Universal mains input — 115/230 V AC, 50/60 Hz.
• Rugged & portable — 350 × 270 × 220 mm, ~24 kg, 0 °C to +50 °C.

Applications

The MOM690 is ideal for substation and industrial test teams measuring the contact resistance of high-voltage circuit breakers, disconnectors, busbar and line joints — where the highest test currents or AC testing capability are needed.
