PROVA-11 AC/DC mA Clamp Meter
The PROVA-11 is a high-resolution AC/DC mA clamp meter for low-current electrical measurement. It measures AC current with True RMS response, DC current, and AC/DC voltage, and is useful for current and voltage checks where the meter range, safety category, and 23mm jaw opening fit the circuit.
Key Capabilities
- AC current measurement from 0 to 30A with True RMS response.
- DC current measurement from 0 to 40A.
- High current resolution: 0.1mA for AC current and 1mA for DC current.
- AC/DC voltage measurement up to 400V with 0.1V resolution.
- One-touch zero for DCA adjustment.
- 23mm maximum conductor jaw opening.
- 3 3/4 digit LCD with 40-segment fast bargraph display for transient observation.
- Max/Min, data hold, overload indication, low-battery indication, and auto power-off functions.

When to Choose This Meter
- Choose it when you need milliamp-level AC or DC current measurement without breaking the circuit.
- Use it for current checks where a 23mm clamp jaw and 30A AC / 40A DC range fit the conductor and circuit.
- Use True RMS AC measurement when the waveform may not be a simple sine wave.
Before Ordering
- Confirm the current range, voltage range, safety category, conductor size, and measurement method against your circuit before use.
- Confirm the included accessories and battery shipping arrangement before purchase if your order requires a complete ready-to-use kit.
FAQ
