sanwa CD771 Digital Multimeter
The sanwa CD771 Digital Multimeter is a compact, user-friendly digital multimeter designed for everyday electrical troubleshooting and measurement tasks. Its 4000-count LCD and clear numeric/indicator layout make readings easy to scan, while auto/manual range selection and data-hold/backlight controls let users capture and view measurements reliably even in dim conditions.
Built to the IEC safety standards, the CD771 provides robust protection for common workshop and field environments (CAT.III 600 V / CAT.II 1000 V) and houses fuses with high breaking capacity to guard the input circuits. Practical features like a safety cap on the current terminal, a continuity buzzer with LED, and secure test-lead storage emphasise safe, everyday usability for technicians and hobbyists alike.
Functionally versatile, the CD771 measures DC/AC voltage, resistance, frequency, capacitance, diode/continuity checks, and DC/AC current up to its rated limits. Auto power-off, relative measurement, and a special battery load test for 1.5 V cells add convenience for diagnostic and battery-checking workflows, while the rugged double-moulded body improves grip and drop resistance on the job.
Features:
- Safety design compliant with IEC61010-1; current terminal protected with a safety cap.
- Continuity confirmed by buzzer and red LED lamp.
- Large, eye-friendly display with 4000 counts.
- Frequency and capacitance measurement functions provided.
- Easy-to-hold, double-moulded body (elastic elastomer outer).
- Test probes can be secured to the meter body for storage.
