Mastech MS5908A Professional Digital Circuit Analyzer

Description

The Mastech MS5908A is a professional digital circuit analyzer for inspecting and locating faults in low-voltage AC electrical distribution lines. It is particularly designed for circuits with a 110V input voltage and uses a US-style plug. The MS5908A is useful for electricians, home inspectors, and DIY enthusiasts for diagnosing electrical problems and ensuring safety.

Key Features

• True RMS AC voltage measurement: Measures AC line voltage with high accuracy.
• GFCI and RCD testing: Tests the reliability of Ground Fault Circuit Interrupters (GFCI) and Residual Current Devices (RCD), including trip time and current.
• Impedance measurement: Measures the impedance of the live, neutral, and earth wires to identify circuit integrity issues.
• Voltage drop analysis: Measures the percentage of voltage drop under different artificial loads (12A, 15A, and 20A).
• Socket wiring check: Identifies correct wiring connections in 3-wire plugs, including live, neutral, and ground.
• Peak voltage measurement: Measures the peak line voltage.
• Neutral-ground voltage: Measures the voltage between the neutral and ground wires.
• Large LCD display: Features a backlit LCD for clear readings in various lighting conditions.
• Data hold: Allows the user to freeze the current measurement on the screen.
• Auto power-off: Conserves battery life by automatically shutting down after a period of inactivity.
