For easy and quick measurement of direct and alternating currents up to 40 A, the circuit does not need to be interrupted during measurement, unlike with multimeters. The device is perfectly suited for servicing machines in control cabinets. It features a high-contrast display with 4000 counts, which is exceptionally readable in all lighting conditions. Especially in poorly lit control cabinets, this model outperforms conventional current clamps. The display shows 4-digit values up to 3999, regardless of the position of the decimal point.

The True RMS measurement allows for accurate measurement of asymmetrical voltages and currents that deviate from the fundamental sine wave shape. Asymmetrical voltages often occur with power controllers such as dimmers, speed controllers, switched-mode regulators, pulsed chargers, or electronic speed controllers in model building. Conventional average-value measuring devices can show significant measurement deviations in these measurement tasks.

ISO calibration is required when the measuring device is used in an ISO 9001 certified environment for measurement tasks. An ISO certification is also helpful and often a prerequisite for experts, acceptance points, or testing laboratories.
