Operation Instructions
-
Connect the BNC interface to the oscilloscope (or other instruments), then plug the USB cable to power the probe.
-
Select the appropriate range according to the current range.
The corresponding button light will turn Green. -
Adjust the oscilloscope settings:
- Input impedance: 1M
- Select probe to Current or display as A
- Set attenuation ratio on the corresponding channel:
- 100A -> 0.01V/A to 100X
- 10A -> 0.1V/A to 10X
-
Press the Zero button to do zero calibration. After a successful calibration, the buzzer will beep one time. If it beeps three times, it means zero calibration has failed. Manual adjustment is also possible. Note: Do not move it in a large range after zero adjustment is completed, as the external magnetic field may have a slight influence on the DC zero position.
-
Clamp the conductor under test according to the direction indicated by the jaws. Note: If the measured current flows in the opposite direction, the output will be negative.
-
Adjust the oscilloscope to get the best waveform.
Product Introduction
The CP2100 series current probe is a BNC type that can measure both DC and AC. With a split design and compact look, it also can be connected to multimeters via a connector. Automatic and manual zero adjustments, powered by USB, no need for additional power supply, making measurement more convenient, often used in motor drives, industrial frequency, inverters, power supplies, avionics, and other fields.
Safety Precautions
- The measurable circuit should be CAT II 600V or below
- Do not measure bare conductors
- Do not touch the measured conductor and sensor head during the measurement
- Do not use in a humid environment
- Do not touch the instrument or the measured object with wet hands
- Please ground this product through the USB power cord
- Please use this product as required
