Ermenrich Zing DZ70 Digital Clamp Meter

The Ermenrich Zing DZ70 is a professional measuring tool for electricians, HVAC specialists, and power electronics technicians. The device measures AC and DC current up to 1,000A without breaking the circuit, and it also replaces a multimeter. It features capacitance measurement up to 40mF, temperature from −40°C to +1,000°C, frequency, and duty cycle.

Accurate measurements with distorted signals

The device measures true root mean square (True RMS). Therefore, readings remain accurate even when the waveform is far from sinusoidal: in server equipment circuits, switching power supplies, LED lighting, and variable frequency drive power circuits. The clamp meter measures AC and DC current up to 1,000A and voltage up to 600V. This is sufficient for residential electrical systems and most 230/400V industrial networks.

Wide capacitance measurement range

The capacitance measurement limit of this model is 40mF (40,000µF), whereas many budget multimeters are limited to hundreds of microfarads. With the Ermenrich Zing DZ70, you can test large smoothing capacitors in welding inverters, industrial rectifiers, and high-power audio amplifiers. The frequency meter with a 4kHz limit and the duty cycle measurement function are suitable for monitoring mains frequency and low-frequency PWM signals.

HVAC and refrigeration equipment maintenance

The device is highly useful for HVAC (heating, ventilation, and air conditioning) specialists. With the thermocouple, it is convenient to check the operation of air conditioners, freezers, and heat pumps as well as monitor the temperature of refrigerant lines. The temperature measurement range is −40°C to +1,000°C. The device is designed to operate at ambient temperatures from −10°C to +50°C.

Diagnostics and ease of use

The audible continuity test triggers at a resistance below 35Ω. This low threshold reduces the risk of false triggers, and a test current of less than 1mA is safe for electronic components. The diode test mode helps you to quickly find faulty semiconductors. Readings are displayed on a 4,000-count screen with a backlight. The device complies with IEC 61010-1 (CAT III 600V) and is powered by a single 9V battery (not included).

Key features:

• True RMS ensures accurate measurements in networks that are affected by interference from variable frequency drives and switching power supplies
• High currents up to 1,000A (DC/AC) enable safe diagnostics of power mains and busbars without shutting down equipment
