The Ermenrich Zing DZ20 is a versatile digital clamp meter that is designed for auto electricians, installers, and repair technicians. The 30mm jaw opening easily accommodates thick power cables or individual conductors, allowing for safe current measurement without breaking the circuit.
Automotive electrical and power line diagnostics
The main advantage of this model is its DC current measurement capability. This makes the clamp meter an indispensable tool in the garage for checking the starter, testing alternator output, or finding parasitic battery draws. In residential and industrial networks (up to 600V), the device helps assess the actual load on circuit breakers, detect phase imbalances, and test solar panels.
Component and motor testing
The clamp meter is highly effective for component-level repairs. Capacitance measurement up to 100µF allows for the quick testing of start capacitors in air conditioners and pumps. The diode test function helps diagnose rectifiers in power supplies, welding machines, and automotive alternators. Frequency and duty cycle measurements are provided for working with inverters and PWM controllers.
Troubleshooting and ease of use
Locate problems quickly: The audible continuity test detects open circuits, while the non-contact voltage (NCV) detector finds live wires or hidden wiring. The thermocouple helps monitor radiator heating and air conditioner output temperatures. All readings are displayed on a clear screen, and the bright backlight is invaluable when working in poorly lit electrical panels or basements. The device is powered by a single 9V battery, with an auto-off function to preserve battery life.
