The PEAKMETER MS5910 combines residual-current-device testing and earth-fault loop resistance measurement in one portable professional instrument. It is designed for electrical installation inspection, commissioning, fault finding and periodic safety verification.
Key features
- Measures RCD trip-out current and trip-out time
- Measures contact voltage and loop resistance
- Selectable RCD test levels including 10 mA, 30 mA, 100 mA, 300 mA and 500 mA
- 0.5×, 1× and 5× RCD test-current multipliers
- AC voltage measurement up to 440 V
- Automatic and manual ranging
- Stored test results with USB 2.0 PC transfer
- Backlit display, automatic power-off and low-battery warning
- Over-temperature protection for field safety
Typical applications
- Electrical installation commissioning
- RCD and earth-leakage protection verification
- Earth-fault loop assessment
- Residential, commercial and industrial maintenance
- Fault finding following nuisance tripping or protection failures
