Micsing CP2100B AC and DC Current Probe
Specifications:
- Model:
- CP2100A
- CP2100B
-
- Bandwidth:
- CP2100A: DC~800KHz
- CP2100B: DC~2.5MHz
-
- Rise time:
- CP2100A: 437.5ns
- CP2100B: 140ns
-
- Range:
- 10A/100A
-
- Output sensitivity:
- CP2100A: 0.1V/A (10A), 0.01V/A (100A)
- CP2100B: 150ns (10A), 200ns (100A)
Operation Instructions:
- Connect BNC interface to the oscilloscope (or other instruments), then plug the USB cable to power the probe.
- Select appropriate range according to 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 corresponding channel, 100A0.01V/Ato 100X, range 10A0.1V/Ato 10X.
- Press Zero button to do zero calibration, after success, the buzzer will beep one time; if beep three times meaning zero calibration has failed; can also go Manual to adjustment. The external magnetic field may have slight influence on the DC zero position, do not move it in a large range after zero adjustment is completed.
- 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. Note: When the current exceeds the range, the buzzer will beep for a long time and the button light will flash.

FAQ:
-
Q: What should I do if the zero calibration fails?
A: If the zero calibration fails and the buzzer beeps three times, you can try manual adjustment. Avoid moving the probe in a large range after zero calibration. -
Q: What does it mean if the button light flashes and the buzzer beeps for a long time?
A: This indicates that the current being measured exceeds the range of the probe.
Product Introduction
The CP2100 series current probe is a BNC type that can measure both DC and AC. With split design and compact look, it also can be connected to multimeters via connector. Automatic and manual zero adjustment, powered by USB, no need 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 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
