Catalog #: 4930876
True-RMS AC Leakage Current Clamp with Mechanical Lock Jaw, 6000 Counts Digit Large Scale
- Overview
- Specifications
- Summary
Product Highlights
- Low influence of external low frequency magnetic fields: @ IN: 3.500 mA - 600.0 mA ≤ 30 A/m, operating class 2
- True-rms measurements for accuracy when measuring complex, non-sinusoidal waveforms
- Mechanical jaw lock - jaw opening 1.2 in (30 mm)
- Highest resolution of 0.001 mA, measure up to 60 A
- Broad frequency range 15 Hz to 1 kHz
- Selectable filters:
- Low Pass 50/60Hz filter to perform measurements on equipment driven by Variable Frequency Drives (VFDs) or affected by high frequency noise
- Appliance Filter to conduct leakage current measurements on appliances
- No filter
- Selectable limits: 0.25 mA, 0.5 mA, 3.5 mA, 10 mA, 12 mA
- Max readings and hold function
- High safety rating: CAT III 600 V
- Battery-saving design with an auto backlight off and auto power off
Applications
- Measure:
- Earth and differential leakage currents
- Leakage currents through the earth (PE) conductor
- Appliance current consumption without interruptions to the circuit
- Trace the source of earth leakage current
- Identify intermittent GFCI trips without switching equipment off
- Check a system for an electrical break of insulation where current is flowing to the ground
- Where industrial leakage current testing is required
Each Unit Includes
- 2 - 1.5 V AAA batteries

[1] Crest Factor (C.F.) may be up to 3.0 as 3000 counts. For non-sinusoidal waveforms: Add 1.0% for C.F. 1.0 to 2.0 / Add 2.5% for C.F. 2.0 to 2.5 / Add 4.0% for C.F. 2.5 to 3.0. Position error of clamp: +/- 1% of LCD reading.
[2] Minimum reading is 0.010 mA.
[3] When operating in magnetic fields up to ≤ 30 A/m, add ±0.3 mA error to accuracy |
