Product Usage Instructions

Operation Steps:

1. Connect to the oscilloscope: Set the oscilloscope input impedance to 1M, connect the probe BNC end to the oscilloscope (ensure proper grounding).
2. Power the probe: Use a standard adapter to power the probe. The indicator light turns green after power on.
3. Connect the Device Under Test (DUT): Ensure the coil plug is inserted correctly and the wire or pin under test passes through the appropriate position of the coil.
4. Power up the DUT.
5. After test: Disconnect the circuit first, then unplug the coil.
6. Disconnect probe power.

Safety Precautions:

• Use within safe voltage range.
• The equipment connected to the probe must be reliably grounded.
• Inspect the outer skin of the Rogowski coil before use. Stop using it if damaged.
• Ensure the circuit under test is turned off before connecting the probe.
• Use the adapter that comes standard with the probe.

8. Current direction: When the current flows in the marked direction, the output ispositive, otherwise it is negative.

Precautions

• to ensure accuracy, the wire being measured should be positionedas much as possible between X and Y in the right diagram, where X is the center of coil and Y is the midpoint of the coil circumference.
• to ensure accuracy, the wire should avoid the coil junction asmuch as possible during measurement (shadow area).
• try to stay away from strong magnetic field interference sources asmuch as possible to avoid measurement errors.
• the coil can be placed around the wire being measured to measurethe interference signals in the surrounding area, to determinewhether there is strong interference nearby.

Operation steps

1. Connect to the oscilloscope: Set the oscilloscope input impedance to 1MΩ, connect the probe BNC end to oscilloscope (make sure the oscilloscope is properly grounded);
2. Power the probe: Use standard adapter to power the probe. Indicator light turns green after power on;
3. Connect the DUT: make sure that the coil plug is inserted in place and the wire or pin under test passes through the appropriate position of the coil.
4. Power up the DUT.
5. After test, disconnect the circuit first, then unplug the coil.
6. Disconnect probe power.
