This document describes a battery-powered, true RMS, auto-range multi-function digital multimeter with a 6000-count LCD display and adjustable backlight brightness.
Function Description
The multimeter is designed for various electrical measurements and includes several features to enhance usability and safety.
Measurement Capabilities:
- AC/DC Voltage: Measures both AC and DC voltages. When testing AC voltage, the vice display shows frequency; when testing DC voltage, it shows regular temperature.
- Resistance: Measures electrical resistance.
- Continuity: Tests for continuity, indicated by a beeper when resistance is below 50Ω.
- Diodes: Tests diodes, showing "OL" if the polarity is reversed or the diode is broken.
- Capacitance: Measures capacitance, with readings stabilizing on the display.
- Frequency/Duty Cycle: Measures frequency (low voltage and high frequency) and duty cycle, with the vice display showing the duty cycle.
