Victor Professional AC / DC Leakage Current Tester – 60A Range,1mA Resolution, USB Data Logging, Auto-Ranging for Automotive & Industrial Use 140D

True AC / DC Leakage Current Tester for Automotive & Industrial Applications

• Unlike many clamps that measure only AC, the Victor 140D is a true AC / DC leakage current tester, capable of measuring 0mA to 60.0A for both alternating and direct current.
• Specifically designed for automotive dark current (parasitic draw) detection – identify battery drain caused by faulty modules, relays, or aftermarket installations.
• Also ideal for DC leakage current in solar arrays, battery banks, telecom power systems, and industrial controls.
• When you need a versatile AC / DC leakage current tester, the 140D delivers on every front.

Unique Jaw Shape for Tight Access

• Jaw size: 16mm × 18mm (rectangular) – a compact, non-circular design for clamping around thick or awkward cables.
• Perfect for automotive fuse boxes, battery terminals, crowded control panels, and busbars.
• This AC / DC leakage current tester gets into spaces where round-jaw meters simply cannot fit.

1mA Resolution for Sensitive Leakage Detection

• Resolution: 1mA AC / DC – sensitive enough to detect standby currents, insulation degradation, and early-stage leakage.
• Whether you're chasing a 5mA ground leak or a 20mA parasitic drain, this AC / DC leakage current tester reveals the problem clearly.
• 4-digit LCD display with 2 samples/sec refresh rate ensures stable, readable values.

USB Interface with Data Logging & PC Monitoring

• Includes USB port, communication cable, and monitoring software – rare at this price point.
• Features:
  • Online real-time monitoring via computer
  • Historical data query and playback
  • Dynamic display of live, max, min, and average values
  • Alarm value setting with visual indication
  • Save, print, and export historical data
• Perfect for long-term leakage current tester trending, shift handover reports, or compliance logging.

99-Group Data Storage

• Stores up to 99 readings locally on the device.
• "FULL" flash indicator when memory is exhausted.
• No need to keep a laptop connected – use as a standalone AC / DC leakage current tester, then upload later.

Fully Automatic Ranging – No Dial Twisting

• Auto-ranging from mA to A – the meter selects the best range automatically.
• Polarity indication: automatically displays "–" for DC measurements.
• Over-range display: "OL A" symbol prevents misinterpretation.
• Wire position guidance: for best accuracy, place the conductor in the center of the jaws.

Wide Frequency Response for AC Leakage

• AC frequency response: 45Hz to 400Hz – covers standard power (50/60Hz) and higher-frequency harmonics.
• Reliable as an AC / DC leakage current tester for motor drives, UPS outputs, and generator systems.

Safety & Electrical Durability

• Dielectric strength: AC 3700V/rms between core and housing – safe for live troubleshooting.
• Line voltage rating: 600V and below – suitable for low-voltage distribution panels and automotive systems (12V/24V/48V).
• Non-contact measurement via Clamp CT – no need to break the circuit.

User-Friendly Display & Controls

• 4-digit LCD with 35mm × 21.5mm viewing area.
• Data hold (DH) freezes the reading for recording in dark or tight spaces.
• Low battery warning at 7.2V (9V battery).
• Auto power-off after 5 minutes – conserves battery life during fieldwork.

Built for Tough Environments

• Operating temperature: -10℃ to 50℃ at <80% RH.
• Storage down to 60℃ – leave it in a service van without worry.
• Weight: only 220g (including 6F22 9V battery) – fatigue-free for all-day use.
• Working current: maximum 20mA – very low power draw.

Limit Temperature Error Indication – Full Transparency

• Specified error increase of 2%rdg below 0℃ and above 40℃ – honest engineering data you can trust.
• No hidden performance degradation – this AC / DC leakage current tester tells you exactly what to expect.
