FNIRSI DMC-100 DC/AC Current Voltage Clamp Meter Multimeter

The FNIRSI DMC-100 is a digital clamp-style multimeter for diagnosing drone power systems, bench power supplies, and field charging setups. By measuring DC and AC current directly through the jaws, it allows you to read live amp draw without cutting wires or soldering inline shunts. This makes it an essential tool for thrust testing individual motors or checking total system loads on high-draw FPV and heavy-lift rigs.

Key features

• Clamp-style jaw for non-invasive current measurement without breaking circuits
• Measures both DC and AC current and voltage
• Integrated digital OLED/LCD screen for high contrast and readability on the bench
• Combines non-contact amp sensing with standard multimeter voltage functions

For builders working with high-current 6S to 12S builds, an inline clamp meter provides a fast, safe way to verify ESC telemetry and diagnose power bottlenecks without exposing live high-voltage joints.
