Description
The KM-TBC1 measures AC and DC voltage, resistance, and frequency with full autorange across all functions, eliminating the need to select the correct range manually. True RMS ensures accurate readings on non-sinusoidal waveforms common in modern electronics and variable-speed drives.
The NCV (Non-Contact Voltage) detector lets users identify live conductors without touching them. Additional safeguards include out-of-range indication, negative polarity indication, low battery warning, and automatic power-off. It is rated CAT III 600 V and meets IEC61010-1, IEC61010-2-033, and EN61326-1.
Key Features
- 4,000-count 2.4-inch backlit LCD display
- Autorange across all measurement functions
- True RMS AC voltage and current measurement
- NCV (Non-Contact Voltage) detection
- Built-in flashlight for low-light use

Product Benefits
- Autorange removes the risk of over-range damage and speeds up measurement — no manual range switching
- True RMS gives accurate AC readings on loads with non-sinusoidal waveforms such as motors, inverters, and dimmers
- NCV lets you check for live voltage at a socket or cable end before touching it, improving jobsite safety
- The built-in flashlight means a single tool serves in both electrical panel and dark-space situations
- Data hold freezes the display for reading in awkward positions where viewing the meter is difficult
- CAT III 600 V rating covers measurements on distribution panels and fixed installations
