The EDM-80 DC Voltmeter 0-3V measures direct current potential across a narrow low-voltage range. Inside the ABS casing, a moving coil mechanism drives the needle for real-time voltage tracking. Under road dust or lab conditions, the ±2.5% accuracy class maintains reliable data.
Key Features
- Anti-parallax Mirror Scale: Behind the knife-edge pointer, a mirror strip eliminates reading errors. Eliminates viewing angle bias during measurement.
- ABS Plastic Desk Stand: 175g weight. Inside 120x80x85mm unbreakable housing, internal coil components survive impact. Resists damage from common lab drops.
- 0-3V DC Range: 0-3V range. Throughout this range, 0.1V scale increments track data. Tracks small voltage drops in circuits.
- ±2.5% Accuracy Class: Across the full scale deflection, the moving coil maintains precision. Reduces error margins in school experiments.
Frequently Asked Questions
How to read 0-3V analog voltmeter?
Align the knife-edge pointer with its reflection in the mirror scale. This method removes parallax error for a precise 0.1V increment reading.
What is the accuracy of EDM-80 voltmeter?
This meter operates within a ±2.5% accuracy range of the full scale. The moving coil design maintains this precision during standard DC measurements.
