What to look for in a Knightsbridge multimeter
Knightsbridge multimeters are designed for both professional electricians and serious DIY users. When choosing a model, the most important factor is safety rating. Look for CAT III or CAT IV ratings for mains voltage work. True RMS capability is essential for accurate readings on non-sinusoidal waveforms found in modern electronics. Display quality, including backlight and count resolution, affects readability in dark panels. Build quality and lead durability are also common points in owner reviews.
Mistakes to avoid when buying a multimeter
Many buyers choose a meter with insufficient safety ratings for their work environment. A CAT II meter is not safe for measuring mains circuits. Another common mistake is ignoring input protection fuses. High-energy circuits can cause catastrophic failure in meters without proper fusing. Finally, avoid buying a meter without continuity buzzer for quick circuit testing.
Knightsbridge KBM63C
Best OverallPros
- Accurate true RMS readings
- CAT III safety for mains work
- Backlit display for dark spaces
Cons
- No temperature measurement
- Leads could be more flexible
The Knightsbridge KBM63C is the top choice for electricians needing reliable measurements on variable frequency drives and lighting controls. Its true RMS technology ensures accuracy on distorted waveforms. The CAT III 600V rating provides adequate protection for most commercial and residential electrical panels.
Owner reviews consistently praise the clear backlit display and robust construction. The auto-ranging function simplifies operation. Some users mention the included test leads are a bit stiff, but the meter itself performs reliably over years of use.
Knightsbridge KBM45C
Best Auto-RangingPros
- Non-contact voltage detection
- 6000 count high resolution
- Data hold function
Cons
- No low impedance mode
- Battery access could be easier
The KBM45C adds non-contact voltage (NCV) detection, which is useful for quickly identifying live wires without touching them. The 6000-count display offers better resolution than basic 2000-count meters, allowing more precise readings on low-voltage electronics.
Users appreciate the auto-ranging feature that eliminates manual range selection. The backlit display works well in dimly lit breaker panels. Some owners note the battery compartment requires a screwdriver to open, which prevents accidental battery loss but can be inconvenient.
Knightsbridge KBM20C
Best CompactPros
- Very portable and lightweight
- Simple one-hand operation
- Good for basic troubleshooting
Cons
- CAT II only, not for mains panels
- No backlight on basic model
The KBM20C is designed for quick checks on low-voltage circuits, automotive work, and electronics. Its compact size fits easily in a pocket or small tool pouch. The manual ranging keeps the interface simple for beginners.
Owner reviews highlight its convenience for on-the-go testing. It is not suitable for mains electrical work due to the CAT II safety rating. The lack of backlight can be a limitation in dark environments. It is best kept as a secondary meter for light duty.
Knightsbridge KBM10C
Best BudgetPros
- Very affordable price
- Includes continuity buzzer
- Simple and easy to use
Cons
- Manual ranging only
- No backlight or data hold
The KBM10C is the entry-level Knightsbridge multimeter, designed for homeowners and hobbyists. It covers the basics: AC/DC voltage, DC current, resistance, and continuity. The continuity buzzer is responsive for checking fuses and wires.
Owner reviews confirm it works reliably for battery checks, outlet testing, and simple circuit diagnostics. It lacks advanced features like auto-ranging or true RMS. For occasional use around the house, it offers good value. Do not use it for professional electrical work.
Knightsbridge KBM70C
Best AdvancedPros
- Temperature measurement function
- Low impedance (LoZ) mode
- True RMS accuracy
Cons
- Higher price point
- Larger and heavier than others
The KBM70C is the most feature-rich Knightsbridge multimeter, adding temperature measurement via a thermocouple probe and a low impedance (LoZ) mode. LoZ mode helps eliminate ghost voltages that can confuse standard meters, giving more reliable readings on circuits.
Owner reviews from HVAC technicians and advanced electricians praise the temperature function for checking heating systems. The true RMS and CAT III rating make it suitable for commercial work. It is bulkier than other models, which some users find less convenient for tight spaces.
