High-sensitivity Current Probe 701917 DC to 50 MHz 701918 DC to 120 MHz Low noise compact current probe for measuring low level currents from 1 mA to 5 A. Best suited for design and verification applications requiring high-sensitivity at low currents. High-sensitivity (10x more sensitive than previous models) In comparison with existing models (701928/701929/701932/701933), the 701917/701918 has 10 times higher sensitivity (Output rate: 1 V/A). By using these probes, low current of about 1 mA can clearly be observed. Slim and light weight sensor head The sensor head is smaller than existing models, making it easy to use in narrow spaces. Automatic zero-adjustment and demagnetization Zero-adjustment can be done by simply pushing the button on the termination box. Demagnetization can also be done by holding down the DEMAG button for a quicker setup. Supports DL/DLM/SL series Adopted BNC connector as the output terminal. The power can be provided from the probe power option on a DL/DLM/SL series instrument by the probe power supply. Application •LED driver, controller, power supply verification •Evaluation of the embedded power supply •Measurement of the power consumption of a low voltage device (FPGA) •Evaluation of the embedded component for household appliances and car electronics.
