Qiilu ETCR6900A AC Flexible Clamp Meter — Measure Up to 5000A with Confidence
The Qiilu ETCR6900A AC Current Flexible Clamp Meter is a professional-grade electrical measurement tool engineered for industrial, commercial, and heavy-duty electrical work. With an extraordinary AC current range of 0–5000A and AC voltage measurement up to 6000V, this meter handles the demands of large-scale power systems, generator installations, transformer testing, and more — all with ±2% accuracy.
The flexible Rogowski coil design (approx. 150 mm inner diameter, 380 mm length) wraps easily around large bus bars, cable bundles, and conductors in tight or densely wired panels — no need to disconnect circuits during measurement. Made in Mainland China.
Key Features
- Wide Measurement Range: AC current 0.00A–5000A; AC line voltage 600V and below; rated for up to 6000V applications
- Backlit LCD Display: Clear 35×21.5 mm digital readout with backlight — easy to read in low-light conditions, electrical cabinets, or confined spaces
- Strong Anti-Interference: Flexible CT coil with no magnetic hysteresis effect ensures stable, accurate readings even near high-EMI environments
- Peak Hold Function: Captures transient peak current values — simply long-press POWER during testing to lock and display the peak reading
- Data Hold & 99-Group Storage: Freeze readings instantly with Data Hold (DH symbol); store up to 99 measurement groups for later review
- Flexible Coil Access: The slim 7.5 mm coil thickness navigates narrow spaces and areas with dense wiring that rigid jaw clamps cannot reach
- Auto Frequency Recognition: Automatically detects 50 Hz or 60 Hz supply frequency
- CE Certified: Meets IEC1010-1, IEC1010-2-032, CAT VI (1000V), IEC61326 safety standards

Frequently Asked Questions
Q: What is the maximum AC current this flexible clamp meter can measure?
A: The Qiilu ETCR6900A flexible clamp meter measures AC currents from 0.00A up to 5000A, making it ideal for large industrial transformers, switchboards, bus bars, and high-load commercial electrical systems.
Q: Does the flexible coil work in tight or densely wired panels?
A: Yes. The coil is only ~7.5 mm thick and ~380 mm long, allowing it to snake through narrow conduit areas and crowded wiring cabinets where a traditional rigid-jaw clamp meter simply cannot fit. The ~150 mm inner diameter also accommodates large-diameter conductors and cable bundles.
Q: What does the Peak Hold function do?
A: The Peak Hold function captures the highest transient current value during a test cycle. Simply long-press the POWER button while measuring to lock and display the peak reading — extremely useful for detecting inrush currents during motor startups or other brief high-current events.
Q: Is a battery included with the meter?
A: No battery is included. The meter requires one 9V 6F22 zinc-manganese dry battery (a standard 9V block-style battery), which is available at most hardware and electronics stores.
Q: What safety standards does this clamp meter meet?
A: The ETCR6900A is CE certified and complies with IEC1010-1, IEC1010-2-032, Pollution Degree 2, CAT VI (1000V), and IEC61326 — meeting internationally recognized safety and electromagnetic compatibility standards for professional electrical test instruments.
