The RP1001C current probe enables a general purpose oscilloscope to display AC and DC current signals upp too 100A Peak (70A RMS).The RP1001C current probe can also make AC and DC measurments with a multimeter by using the BNC-to-banana plug adapter.Figure 1 RP1001C Current ProbeConnection between the Current Probe and Oscilloscope Set the coupling mode of the oscilloscope to DC and connect the BNC connector of the RP1001C current probe to the oscilloscope input via dual-BNC coaxial cable. Move the Range switch to the 10 mV/A or 100 mV/A position to turn on the RP1001C current probe. At this point, the green battery indicator lights. Use the zero adjustment knob to adjust the probe to the proper DC offset. Note: when measuring DC signals, accurate DC value is possible only when the current probe is fixed at a certain position, otherwise, the change of the position of the probe will cause the DC drift. When measuring AC signals, users can move the current probe. Before connecting the current probe to circuit, open the test clamp and clamp it onto the conductor as shown in the figure below.Figure 2 Connection between the Test Clamp and Conductor Adjust the probe channel and oscilloscope as necessary to get a clear and stable view of the signal. At this point, you can see both the current components of AC and DC. Set the coupling mode of the oscilloscope to AC to see the current components of AC. The operation method of the current components of AC is the ratio of the voltage amplitude measured through the oscilloscope and the switch range currently selected of the current probe (50 mV/A or 500 mV/A). Note: The current drawn by different devices look much different than that of others. While the RMS current can only be used in low frequency current, the momentary peaks may be quite high. The figure on the next page shows the difference between the line current drawn by a resistive load and a motor controller.
