Victor Leakage Current Tester –AC Current 100A, 10μA Resolution, True RMS, Rechargeable 140B

Ultra-High Resolution for Sensitive Leakage Detection

• As a dedicated leakage current tester, the Victor 140B offers a communication resolution of 10μA – far superior to standard clamp meters.
• Perfect for detecting tiny leakage currents in ground wires, medical equipment, IT systems, and industrial control panels.
• Measures AC current from 60.00mA to 100.0A, with 0.01mA resolution on the lowest range, ensuring no leakage goes unnoticed.

True RMS for Accurate Non-Sinusoidal Signal Measurement

• Unlike average-responding meters, this leakage current tester provides True RMS readings for AC voltage and current.
• Essential for modern electronic loads (VFDs, switch-mode power supplies, LED drivers) where waveforms are distorted.
• Delivers reliable leakage current tester performance even in noisy electrical environments.

Wide AC/DC Voltage Measurement with High Input Impedance

• AC voltage: 6.000V to 600.0V, ±(0.8%+3) accuracy
• DC voltage: 600.0mV to 600.0V, ±(0.5%+3) accuracy
• 10MΩ input impedance prevents circuit loading – a must for any serious leakage current tester.

Compact Jaw Design for Tight Spaces

• Jaw size: Φ27mm – ideal for clamping around single wires, ground conductors, and crowded cable bundles.
• Small jaw enables non-invasive leakage testing without disconnecting wires.
• Lightweight (162g) and slim body (166 × 67.5 × 26 mm) make this leakage current tester easy to carry and operate for hours.

Robust Safety and Overload Protection

• Overload protection up to 60A on mA ranges and 100A on A ranges.
• Voltage input protected up to 600V max – safe for industrial and residential panels.
• Clear "OL" overload indication prevents misinterpretation.
• A truly rugged leakage current tester for daily field use.

Intelligent Features for Efficient Troubleshooting

• Data retention (HOLD) – freeze readings for hard-to-reach measurements.
• Max/Min recording – track intermittent leakage events.
• Alarm indicator light – visual alert for threshold exceedance.
• Auto power-off after 15 minutes – preserves battery life.
• Low voltage prompt – never run out of power unexpectedly.
• Auto-ranging – no manual range selection needed.

Modern Power and Connectivity

• Type-C charging – rechargeable 3.7V lithium battery eliminates disposable batteries.
• No downtime searching for replacements – just plug and charge.
• Ideal for long-term monitoring as a portable leakage current tester.

Clear Display and High Sampling Rate

• 5999-count (3 5/6) LCD display.
• Sampling rate: 3 times per second – responsive enough for dynamic leakage tracking.
• Works in 0 to 40°C, <75%RH operating environment; storage down to -10°C.

Versatile Applications

• Perfect for:
  • Residual current monitoring (RCD/GFCI testing)
  • Leakage detection in uninterruptible power supplies (UPS)
  • Medical equipment leakage testing
  • Data center grounding integrity checks
  • HVAC and industrial control leakage troubleshooting
• Wherever you need a reliable leakage current tester, the Victor 140B delivers.
