What is the difference between manual and auto-ranging multimeters?

When you're selecting a digital multimeter, one of the first things you’ll encounter is the distinction between manual ranging and auto-ranging models. For beginners, this might sound like a technical detail—but it has a real impact on how easy and efficient your measurements will be.

Let’s break down what this difference really means, and help you figure out which type fits your work best.

Manual-Ranging Multimeters: More Control, More Steps

Manual-ranging multimeters require you to know the approximate range of what you're measuring (voltage, current, resistance, etc.) before you begin. You’ll need to turn the dial to the correct range for the most accurate reading.

This can be ideal if you’re working with known values or want more control over measurement resolution. For example, electricians who measure similar voltages daily may prefer manual control.

Example: Some entry-level multimeters on the market, including older Fluke models or budget-friendly brands, often use manual ranging to keep costs low.

Auto-Ranging Multimeters: Convenience and Speed

Auto-ranging multimeters, like the BSIDE S11 or BSIDE A10, automatically detect and set the appropriate range for the measurement you're taking. This makes them much easier to use—especially for beginners or those working with unknown circuits.

Instead of wasting time figuring out the range or switching settings, you simply select what you want to measure (like DC voltage), and the meter handles the rest.

Why Choose Auto-Ranging?

• Faster Measurements

• Fewer Mistakes

• Easier for DIYers & Professionals

Comparing Models: BSIDE vs Other Brands

Final Thoughts

If you're new to multimeters or frequently test unknown values, auto-ranging models like the BSIDE S11 and A10are game-changers. They offer a great balance of ease-of-use, safety, and accuracy. Manual-ranging meters, while less convenient, still hold value for those who want more hands-on control.

In short:

• Auto-Ranging = Better for convenience and general use

• Manual-Ranging = Preferred by experienced users who need specific control
