The multimeter is suitable for universal use in electrical engineering, electrical installation, laboratory applications, telecommunication, training etc.

Thanks to the low-pass filter and low input resistance, it’s especially well suited for measurements at frequency converters.

The instrument can be used in the field and is equipped with an internal, mains-independent power supply
