Product Details
The FMFPAX ETCR6500 is a high-accuracy clamp leaker for measuring AC leakage current, AC line current and on-line current without opening the circuit. Its 35 × 40 mm clamp uses a special alloy core with magnetic shielding, covering 0.00 mA to 300.0 A with 10 µA resolution on lines up to AC 600 V.
Peak hold, data hold, 99-unit memory and an RS232 interface with PC software make it suitable for electrical safety inspection, equipment maintenance and grounding checks.
Key Features
- AC leakage current, AC current and on-line current measurement.
- Range 0.00 mA–300.0 A with automatic range shift, 10 µA resolution.
- 35 × 40 mm clamp jaws; 50/60 Hz automatic.
- Peak hold (HOLD >3 s), data hold with automatic storage.
- RS232 upload and PC software: on-line monitoring, curves, max/min/average, alarm setting.
- CAT III 600 V; auto power-off; low-battery indication.
