Mastech MS8040 Digital Multimeter

Description

The Mastech MS8040 is a bench-type digital multimeter designed for professional use in labs, workshops, and educational settings. It provides high-precision measurements and a comprehensive set of features, including True RMS for accurate readings on both linear and non-linear loads.

Key Features

• Dual Display: Features a large dual display with a 22,000-count resolution and a 44-segment bar graph. The bar graph is useful for visualizing rapid changes in signals, similar to an analog needle.
• True RMS: The True RMS (Root Mean Square) capability ensures accurate AC measurements, even on complex and distorted waveforms.
• Auto and Manual Ranging: Offers the flexibility of automatically selecting the correct range for convenience, and manual ranging for locking into a specific scale.
• PC Connectivity: Equipped with an RS-232 interface and compatible PC software for data logging, analysis, and display on a computer.
• Low-Pass Filter: Includes a 1kHz low-pass filter for filtering out high-frequency noise when measuring AC voltage and current.
• Comprehensive Measurement Functions: In addition to standard AC/DC voltage, current, and resistance, it measures capacitance, frequency, and temperature.
• Dual Power Supply: Can be powered by either an AC main supply or batteries (6x AA and 1x 9V), which is convenient for situations where mains power is unavailable.
• Data Handling: Features include Data Hold to freeze a reading, MAX/MIN to capture the highest and lowest values, Peak Measurement to capture transient peaks, and Relative Measurement to zero out the test leads for more accurate low-resistance measurements.
