About This Instrument

The Vartech V 266 is India's most popular digital clamp multimeter — a proven workhorse trusted by electricians, electrical contractors and maintenance engineers across the country for its simplicity, reliability and outstanding value. With a 1000 A AC current range, 1000 V DC voltage measurement and a 50 mm jaw that fits standard cable sizes, it covers the core measurements that come up every day on site — without breaking the circuit or shutting down the load. The optional external insulation tester module extends it to 2000 MΩ insulation resistance measurement, making it a two-in-one field instrument.

Key Features

1000 A AC clamp current measurement with 50 mm jaw opening — safely measure cable currents up to 1000 A without breaking the circuit or interrupting the load
Dual current ranges (200 A and 1000 A) — use the 200 A range for motors, lighting and branch circuits for better resolution; switch to 1000 A for panel feeders and mains
Optional external insulation tester module (20 MΩ to 2000 MΩ) — convert this clamp meter into an insulation tester at will, eliminating the need to carry a separate instrument
1000 V DC and 750 V AC voltage measurement — covers the full low-voltage distribution range in a single instrument
Resistance measurement (200 Ω and 20 KΩ) with audible continuity buzzer — complete tool for electrical fault finding and circuit verification
Data Hold — freeze the reading on screen so you can record it safely without staying in an awkward position near live conductors
ISO 9001 certified manufacturing — consistent quality across every unit; simple, robust and built for daily field use
