Mastech M9912 Special Application Digital Clamp Meter

Description

The Mastech M9912 is a "Special Application" digital clamp meter, not a standard multimeter from the MAS830 series. Unlike basic multimeters that measure current by inserting probes into the circuit, the M9912 uses a clamp mechanism to measure AC and DC current non-invasively by clamping around a single conductor. This feature makes it particularly useful for electricians, HVAC technicians, and field professionals who need to measure high currents without breaking a circuit.

Key Features

• Specialized clamp design: The primary function of the M9912 is its clamp-on design, which allows for measuring high currents up to 1000 A without direct contact with the conductor.
• Auto and manual ranging: Provides flexibility for both beginners and professionals by automatically selecting the correct measurement range, with the option to switch to manual control.
• Multifunctional measurements: In addition to AC/DC current, the device also measures AC/DC voltage, resistance, and frequency, similar to a standard multimeter.
• High display count: Features a 3200-count LCD with a 33-segment bar graph, offering more precise readings than the 2000-count display on the MAS830 series.
• Backlit display and work light: Includes a backlight for the display and a separate work light, making it suitable for use in low-light environments.
• Continuity and diode tests: Comes with a built-in audible continuity buzzer and a diode test function.
• Data hold: The "HOLD" function allows you to freeze the reading on the display for convenient recording.
• Enhanced safety: The M9912 is safety certified for CAT III 1000V, providing a higher level of protection for professionals working with high-voltage systems.
