Watt (Power Factor) Measurement of Active, Apparent and Reactive Power; W,VA, VAr The current path be measured directly (up to 10A maximum; up to 16A briefly for a maximum of 30 seconds) or with the help of current transformers or current clamp transformers. The meter automatically selects the range which allows for the highest possible resolution of the applied quantities.
4mm Test Lead Notes CATV 600V Measurement Locations 4mm • Ensure the test lead shield is pressed firmly in place. Failure to use the CATIV shield increases arc-flash risk. CATII 1000V Measurement Locations 18mm 18mm • CAT IV shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard wall outlets. Take care not to lose the shields.
