Siglent CP5150 - Current Probe (12 MHz BW, 150 Arms Max. Continuous Current, 300A Peak)

The Siglent CP5000 series uses a combination of Hall effect and transformer technology to enable AC, DC and impulse current measurements. Key features include easy and highly accurate current measurement, wide bandwidth, over-current protection and indication (buzzer and LED), dual range selection, low current measurement, as well as a degauss and auto zero function.

Several models available

The chart below provides a brief overview of probes in the CP5000 series.

Product Features

The images below highlight several main features of the series. There are two format styles of CP5000 current probes.

CP5030, CP5030A

CP5150, CP5500

1. Sensor head
This clamps the conductor being measured and carries out the actual current measurement. It is a precision assembly including a molded component, a ferrite core, and a Hall effect element. It may be damaged if subjected to sudden changes in ambient temperature, mechanical strain or shock. Great care should be exercised in handling it.

2. Opening lever
Operating lever for opening the sensor head. Always use this lever to open the sensor head.

3. BNC output connector
Connects to the BNC input of the oscilloscope. The output of the current probe is terminated internally. You must select the input impedance of the oscilloscope to be 1 MΩ in order to make accurate measurements. If the oscilloscope you are using does not have a 1 MΩ input impedance setting, you can purchase 50 Ω to 1 MΩ adapter.

4. Power indicator LED
When the power adapter is connected, the green LED lights.

5. Overload indicator LED
When the current measured exceeds the range, the red LED lights and the buzzer alarms.

6. Degauss Auto Zero indicator LED
When this key is pressed (Degauss AutoZero), the green LED lights. If degaussing succeeds, the buzzer will make two short sounds. If degaussing fails, the buzzer will make a long sound.

7. Range indicator LED
The green LED indicates the selected range.

8. Degauss AutoZero Key
When this key is pressed, the probe will degauss and AutoZero. This takes approximately 5 seconds.

9. Range select Key
When this key is pressed, the probe will switch the range.

• The CP5030/A has two ranges (30A and 5A). The Current Transfer Ratio is 0.1V/A and 1V/A.
• The CP5150 has two ranges (150A and 30A). The Current Transfer Ratio is 0.01V/A and 0.1V/A.
• The CP5500 has two ranges (500A and 75A). The Current Transfer Ratio is 0.01V/A and 0.1V/A.

10. Offset (Up) Key
When this key is pressed, the offset will increase.

11. Offset (Down) Key
When this key is pressed, the offset will decrease.

12. Power plug
Connect this to the power adapter (DC 12V/1.2A)

13. Coarse adjustment trimmer
This adjustment should only be carried out if the probe offset is outside the range of the zero adjustment dial.
