Buying Guide: What to Look for in a Multimeter
Before jumping into the reviews, here are some factors you must consider:
1. Accuracy
Look for True RMS meters for precise AC measurements.
High-end models (Fluke, Keysight) offer excellent accuracy.
2. Auto-Range vs Manual
Auto-range saves time by automatically selecting the right measurement range.
Manual range is cheaper but less convenient.
3. Safety Ratings
Check CAT ratings (CAT II, CAT III, CAT IV).
Higher CAT = safer for industrial use.
4. Build Quality
Rubberized casing for durability.
Good-quality test probes are a must.
5. Extra Features
Capacitance, frequency, temperature measurement.
Backlit display for dark environments.
Data hold & auto power-off.
