Description
The TES-3050H Digital DC/AC Clamp Meter provides accurate measurements for electricians, technicians, and engineers. Its 3-3/4 LCD with bar-graph shows AC/DC voltage, current, resistance, frequency, and diode readings clearly. Auto-ranging ensures correct readings on all ranges.
The meter uses TRMS measurement with a low-pass filter for AC current and voltage. It offers PEAK hold to capture high AC signals, and MAX/MIN hold to track variations. Audible continuity and diode tests simplify troubleshooting.
Safety and convenience are built in. The meter shows overrange and low battery warnings. It automatically powers off after 30 minutes to save energy. The compact 430g design makes it easy to carry for field or workshop use.
