Clamp meter BM079 600A AC/DC TRMS, AmpTip, TKF, 102126

Functionality and Measurement Precision in Challenging Conditions

The BM079 clamp meter is a device designed with professionals in mind who require reliability when working with AC and DC installations. A key feature of this model is the ability to measure AC and DC current up to 600 A and voltage up to 600 V, with all True RMS values measured while accounting for the DC component. Thanks to the built-in low-pass filter (LPF), the device effectively eliminates interference, which is invaluable when diagnosing systems with inverters or drives.

Special attention should be paid to the unique AmpTip™ function. This is a practical solution for installers working in tight distribution boards or with thin wires. A special notch located at the top of the jaws allows for precise measurement of currents up to 60 A in small-diameter conductors, where standard clamps might be too large or inaccurate. This offers not only mounting convenience but, above all, guarantees correct readings in situations where other meters would fail.

Safety and Advanced Diagnostic Features

User safety is a priority; therefore, the meter meets rigorous safety standards: CAT III 600 V and CAT IV 300 V. The high level of overvoltage and overload protection makes the device resistant to sudden voltage spikes, which often occur when working with outdated installations or during network failures.

Diagnostic functions go beyond the standard measurement of basic electrical quantities:

• Three-phase phase rotation test – allows quick determination of phase sequence without the need to connect additional devices, speeding up work during the commissioning of three-phase motors.
• Peak and inrush current recording – the PEAK-rms mode (80 ms) and inrush current recording help capture transient current spikes during motor start-up, which is crucial when selecting protective devices.
• Non-contact voltage detection (EF) – quick verification of AC voltage presence without touching live parts, increasing safety during preliminary inspections.
• MAX/MIN/AVG mode – automatic recording of extreme average values in real time, facilitating the analysis of unstable circuits.

Additionally, the device is equipped with a backlit LCD display, a HOLD function to freeze the reading, and a relative measurement mode Δ (delta), which facilitates comparing readings with a reference value.

Applications and Measurement Range

The device is widely used in electrical service, industry, and HVAC installations. In addition to its primary clamp functions, the BM079 serves as a full-fledged universal multimeter. This allows for a series of additional tests without the need to carry multiple tools:

• Resistance measurement up to 60 kΩ and continuity test with an audible signal.
• Diode test and capacitance measurement of capacitors up to 2500 µF.
• Temperature measurement in the range from -40°C to 400°C (with a thermocouple probe).
• AC frequency measurement up to 1 kHz.
• Accurate DC current measurement via leads up to 2000 µA (microampere range).

Thanks to its compact dimensions (223 x 76 x 32 mm) and relatively low weight (approx. 234 g), the meter is comfortable to use throughout the entire workday. In summary, the BM079 is a complete tool for an electrician seeking a single device for specialized tasks – from simple continuity measurements to advanced diagnostics of three-phase systems powered by DC and AC. It is worth noting the high measurement accuracy for voltage (up to ±1% + 5 digits) and clamp current (up to ±1.5% for the AmpTip range), making it a reliable tool in the hands of a professional.
