Victor Professional AC High Current Leakage Clamp Meter 10,000A Large flexible coil 690 690AB

Price range: $42.99 through $46.99

The 690, 690A, and 690B form a versatile family of flexible clamp meters engineered specifically for AC high current and leakage current field testing. Unlike traditional rigid-core clamp meters, these instruments use a soft, flexible coil that can be wrapped around busbars, cables, or conductors even in the most congested electrical panels. This design gives each AC high current leakage clamp meter the unique ability to access narrow environments and densely wired locations without compromising measurement quality.

Model selection is straightforward. The 690 offers a 628mm coil (φ200mm inner diameter) with 0.0A–9999A range and 10mA resolution – ideal for large conductors. The 690A provides 0A–10000A range at 0.1A resolution using a shorter 470mm coil (φ150mm inner diameter). The flagship 690B combines 0mA–10000A current measurement (1mA resolution) with full voltage testing capability – AC 0–750V and DC 0–1000V – making it a multifunctional troubleshooting tool. All models maintain accuracy of ±2% (plus digit counts), sample at 2 times per second, and include backlit displays for low-light environments.

  • Designed as a dedicated AC high current leakage clamp meter, the 690 series delivers exceptional performance for on-site testing of high AC current and leakage current. Its flexible coil structure allows installation in dense wiring environments where traditional rigid clamp meters cannot fit.
  • Three well-differentiated models – 690, 690A, and 690B – let you match the instrument precisely to your measurement needs. Whether you require basic high-current testing or advanced voltage measurement capabilities, this AC high current leakage clamp meter family has a solution.
  • The 690B model stands out as a true AC high current leakage clamp meter with integrated voltage testing, covering AC 0–750V and DC 0–1000V at 0.1V resolution and ±1.5%±3dgt accuracy. This eliminates the need to carry separate voltage testers on site.
  • Exceptional current measurement span – from 0.0A up to 10,000A depending on model. The 690B offers 1mA resolution (0mA–10,000A range), the 690A provides 0.1A resolution (0A–10,000A), and the 690 delivers 10mA resolution (0.0A–9999A). Every AC high current leakage clamp meter in the series maintains accuracy of ±2%±3dgt or ±2%±5dgt.
  • Large flexible coil options – 628mm coil length with φ200mm internal diameter (690) or 470mm coil length with φ150mm internal diameter (690A/690B). This design makes the AC high current leakage clamp meter ideal for wrapping around busbars, thick cables, and crowded terminal boxes.
  • Lightweight and compact – body weight only 200g–220g, with body dimensions as small as 151×100×35mm (690A/690B). The soft, flexible coil (φ7.5mm or φ8mm thickness) easily threads through narrow gaps, then wraps around conductors for true non-invasive measurement.
  • Advanced data management functions – the 690 series AC high current leakage clamp meter includes alarm value setting, alarm indication, data hold, cancellation, storage, retrieval, and clearing. The 690 stores 99 groups of data, while 690A and 690B store up to 500 sets – perfect for logging multiple test points.
  • High sampling rate of 2 times per second ensures real-time response to current fluctuations. Combined with backlit display for dark panel environments, this AC high current leakage clamp meter works reliably from -10°C to 40°C (operating) and stores safely from -10°C to 60°C.
  • Clear overload indication – “OL” display prevents misinterpretation of out-of-range signals. Battery voltage level is constantly monitored, showing a low-battery symbol to avoid unexpected shutdowns in the field.
  • Excellent insulation resistance >100MΩ guarantees operator safety and instrument longevity. The AC high current leakage clamp meter is built to withstand harsh electrical environments while maintaining linearity and anti-interference performance.
  • Flexible CT testing method eliminates the need for iron cores, reducing weight and preventing saturation effects at high currents. This technological choice makes the 690 series a truly modern AC high current leakage clamp meter.
  • Packaging includes instrument pack, color box, and manual – the 690B additionally comes with test leads for voltage measurement. Power options: 9V battery for 690, or 3×AAA batteries for 690A/690B, offering convenient field replacement.
  • Display sizes – 35×21.5mm (690) or 45×28mm (690A/690B) provide clear readouts even in low light. The combination of high resolution, wide range, and physical flexibility positions this AC high current leakage clamp meter as a direct replacement for traditional bulky clamp meters.
  • Typical applications – measuring large leakage currents on grounding systems, monitoring AC high current on main feeders, troubleshooting dense control panels, verifying CT secondary circuits, and performing routine safety checks where access is restricted.
