Description
The TES-3040H Digital AC Clamp Meter provides precise measurements for electricians, technicians, and engineers. Its LCD with bar-graph shows AC/DC voltage, current, resistance, frequency, and diode readings clearly. Auto-ranging and low-pass filtering deliver accurate TRMS measurements, even in complex circuits. The meter supports MAX/MIN hold, data hold, and zero adjustment, helping users capture transient signals and perform relative measurements efficiently.
This meter ensures safety and convenience. It alerts users for overrange conditions and low battery. The audible continuity checker and diode test simplify troubleshooting. The meter weighs only 430g, runs on a standard 9V battery, and automatically powers off after 30 minutes to save energy. Its compact design makes it easy to carry for field or workshop use.
