MECO 101P+ TRMS Auto Ranging Digital Multimeter
The MECO 101P+TRMS Auto Ranging Digital Multimeter is a smart, pocket-sized digital multimeter designed for both professionals and DIY enthusiasts. Featuring True RMS technology, it ensures accurate readings even for irregular AC waveforms. Its compact design, coupled with a bright backlit LCD and auto-ranging capabilities, makes it the perfect tool for on-the-go troubleshooting and electrical testing.
Key Features:
-
True RMS (TRMS): Ensures accurate AC voltage and current readings, even with non-sinusoidal waveforms.
-
Auto-Ranging: Automatically selects the correct range for voltage, current, resistance, Frequency, Capacitance - no manual range switching required.
-
Pocket-Size & Portable: Compact form factor for easy handling, storing, and field use.
-
Backlit LCD Display: Clear, easy-to-read measurements even in low-light conditions.
-
Multi-Function Measuring: Supports DC/AC Voltage, DC/AC Current, Resistance, Capacitance, Frequency.
-
Safety: Rated for CAT III 600V and CAT II 1000V.
-
Auto Power Off: Conserves battery when not in use.
-
Relative Measurement (REL Δ): A dedicated Relative switch allows you to store a reference value and display the difference between the stored value and subsequent readings. This is essential for nulling out lead resistance during low-resistance measurements.
-
Data Hold: A simple press of the "Hold" button freezes the current reading on the display, allowing you to record data safely without keeping your eyes on the probes.
-
Audible Continuity Check: Features a fast-response buzzer that sounds when a complete circuit is detected (typically <50Ω).
