Ermenrich Zing DZ120 Digital Clamp Meter

The Ermenrich Zing DZ120 is a professional digital clamp meter with a built-in wattmeter. The device automatically calculates load power in AC and DC circuits, so you don’t need to separately measure current and voltage and then multiply them. The clamp meter is suitable for facility power engineers and electrical equipment commissioning and maintenance specialists. It can also be used for selective measurements during energy audits.

Current up to 1,500A and 52mm jaw opening

The jaws accommodate large-diameter cables, busbars, and bundles of parallel conductors. Both AC and DC current can be measured, which is important for solar installations, battery systems, and electric vehicles. Clamp only one phase or pole conductor at a time. The Inrush function captures short-term inrush current surges, for example, when diagnosing powerful electric motors and transformers.

Accuracy with distorted waveforms

Modern loads often draw non-sinusoidal current: This is how variable frequency drives, LED drivers, switching power supplies, and inverters operate. True RMS technology takes the waveform into account. Therefore, the current and power in such circuits are not underestimated. The built-in frequency meter up to 40MHz and duty cycle meter help to check the frequency at which the drive is operating at the moment of measurement.

Multimeter functions in one device

The capabilities of the Ermenrich Zing DZ120 cover the function set of most professional multimeters. With the thermocouple, the clamp meter measures temperature from −100°C to +1,000°C. You can check the heating of contacts and windings under load or the temperature in freezers. The device also measures capacitance up to 40mF, resistance up to 40MΩ, tests diodes with voltage up to 2.8V, and checks for open or short circuits.

Safety and kit

The device complies with CAT IV 600V and CAT III 1,000V overvoltage categories. The NCV indicator helps to pre-locate a phase but the absence of voltage before work must be confirmed by a contact measurement. The backlit display is easy to read in poorly lit rooms. Power is supplied by a single 9V battery (not included); the auto-off function preserves battery life during prolonged inactivity.
