HEINRICH KOPP 196402109 Handheld Digital Multimeter, CAT II 600 V, Manual Ranging, Diode & Continuity Test, Square Wave Output

With a CAT II 600 V safety rating and a 3.5-digit LCD, the HEINRICH KOPP 196402109 handheld multimeter covers DC voltage up to 600 V, DC current up to 10 A, and resistance up to 2 MΩ. It adds diode test, audible continuity, and a 50 Hz square wave output for signal tracing.

Overview

The HEINRICH KOPP 196402109 is a manual-ranging digital multimeter for electrical troubleshooting, hobby electronics, and field service. It measures DC voltage (200 mV to 600 V), AC voltage (200 V and 600 V), DC current (200 µA to 10 A), and resistance (200 Ω to 2 MΩ). A data hold function freezes readings, and a low battery indicator warns when the 9 V battery needs replacement.
