What Is a Clamp Meter and How Does It Work?
A clamp meter combines the functions of multimeters with a non-contact current sensor. Instead of disconnecting wires or breaking a circuit, you simply clamp the jaws around a conductor to take a live reading. This makes slamp meters ideal for switchboards and other areas where access is tight, or downtime is not possible.
The sensor detects the magnetic field around the conductor and converts it into an accurate current measurement, which is a major safety advantage over traditional testing methods.
Types of Clamp Meters Available
AC Clamp Meters
These are designed for standard AC measurement and are commonly used in residential and commercial electrical work.
AC/DC Clamp Meters
These models measure both alternating and direct current. They are ideal for automotive diagnostics, battery systems, EV charging equipment, and solar installations.
True RMS Clamp Meters
A True RMS digital clamp meter provides more accurate readings when testing modern electronic equipment with distorted or non-linear waveforms.
HVAC and Power Clamp Meters
These specialised slamp meters often include features such as temperature probes, microamp measurement, and inrush current testing, which are useful for HVAC and power quality technicians.
How to Choose the Right Clamp Meter for Your Needs
Choosing the right clamp meter in NZ depends on your work environment and accuracy requirements.
- Current Range: Residential work usually requires a 400-amp model. Industrial technicians may need 1000 amps or higher.
- AC or AC/DC: AC/DC is essential for solar work, automotive systems, and any job involving batteries.
- True RMS: Recommended if you regularly work with inverters, variable speed drives, or modern electronics.
- Safety Rating: Look for CAT III or CAT IV ratings based on the level of electrical exposure you face on the job.

Frequently Asked Questions
It is used to measure current safely without disconnecting wiring, which is helpful for live electrical systems.
AC models measure alternating current only. AC/DC models can measure both and are required for solar, battery, and automotive work.
True RMS provides accurate readings on distorted or non-sinusoidal waveforms. It is recommended for modern electrical environments.
Light commercial or domestic work usually needs a 400-amp range. Industrial applications may need 1000 amps or more.
Yes, but only if it is an AC/DC model.
CAT III is suitable for distribution boards. CAT IV is recommended for main service entrances and outdoor mains.
Clamp meters specialise in current measurement. Multimeters are used to test voltage, resistance, continuity, and other functions. Many professionals use both.
Yes. We offer full calibration services to ensure your instrument remains accurate and compliant.
