Pinza amperometrica BM088 1000A AC/DC TRMS, AmpTip 102195

Precision measurement in difficult conditions and on small conductors

This clamp meter combines the ability to measure current up to 1000A and voltage up to 1000V, while offering advanced True RMS functionality for both quantities. Thanks to this, the device not only measures RMS values but also accounts for the DC component in AC/DC circuits, which is crucial when diagnosing modern installations with inverters or emergency power systems. The built-in low-pass filter (LPF) enables reliable AC voltage readings even in the presence of high-frequency interference, such as that generated by variable-frequency drives.

A specialist advantage of this model is the unique AmpTip™ function. Instead of relying solely on standard clamps, which may be insufficient for thin conductors, the device features a special notch in the upper part of the jaws. This allows precise measurement of currents up to 60A on conductors with small diameters, a task often impossible or highly error-prone using traditional clamp methods. For broader applications, the standard clamp method supports ranges up to 1000A.

Advanced diagnostics and operational safety

The device has been designed with demanding industrial and installation environments in mind. High levels of overvoltage protection and input overload resistance ensure equipment durability even in the event of unforeseen network incidents. The safety classifications CAT III 1000V and CAT IV 600V mean it can be safely used in main distribution boards and at low-voltage connection points.

To facilitate work in poorly lit areas (e.g., basement distribution rooms or behind cabinets), the manufacturer has equipped the model with a backlit LCD display and a built-in flashlight. Additional features supporting diagnostics include:

• CREST mode (5ms) – recording of peak current values, essential for analyzing pulses.
• PEAK-rms mode (80ms) – detection of inrush currents and peak RMS voltages, helping to identify motor startup issues.
• MAX/MIN/AVG function – automatic recording of extreme average values during the measurement period.
• Non-contact voltage detection (EF) – quick verification of AC voltage presence without touching live parts.
• Δ (Delta) mode – ability to compare results against a reference value.

Furthermore, the meter offers basic test functions such as continuity testing, diode testing, resistance measurement up to 60 kΩ, and AC frequency measurement up to 1 kHz. The HOLD function allows freezing the result on the screen, facilitating data recording during one-handed operation.

Practical applications and user benefits

It is worth noting how specific features translate into the daily work of an electrician. Thanks to the AmpTip™ function, which utilizes a special notch in the jaws, precise measurement of currents up to 60A is possible even on very thin conductors – a situation that often precludes the use of the standard clamp method due to the meter's excessively large jaw opening. Meanwhile, the built-in low-pass filter (LPF) together with the True RMS mode ensures accurate AC voltage readings in installations with inverters, where traditional meters often fail due to harmonic interference.

Analysis of dynamic changes in the network is also no problem thanks to the PEAK-rms mode (80ms) and the CREST peak value recorder (5ms). This allows detection of short-term spikes in motor inrush currents or voltage pulses that might be missed during continuous measurement. Operator safety is a priority – the robust construction and compliance with CAT III 1000V / CAT IV 600V standards allow direct work at main power sources without risk of equipment damage or personal injury. Additionally, tools that facilitate work include a flashlight and LCD backlighting for visibility in dark technical areas, as well as the non-contact voltage detection (EF) function, which quickly indicates phase presence without physical contact with the circuit.
