The PQA924 features an advanced auto-configuration function designed to eliminate connection errors and optimize setup time. With the AUTOSET mode, the operator can ensure the correct assignment of clamp sensors, preventing incorrect measurements and discrepancies in recorded electrical values.

4 key reasons to use the AUTOTEST function

Automatically detects connected current transducers, enabling instant configuration with zero margin for error.

Prevents wiring errors that could compromise measurement accuracy.

Avoids inconsistent electrical values and the need for repeated recordings.

Automatically corrects reversed clamp connections, preventing misalignment between voltage and current that could lead to erroneous readings.
