Features: Allows user to safely make floating high voltage measurements while using general purpose oscilloscopes. Maximum differential voltage up to 1000V. Differential amplifier converts and scales floating input signal to a lowvoltage signal referenced to earth ground. The probe can be used on circuits associated with electronic high-power converters, motor speed controllers, switching power supplies, and other high voltage circuits requiring isolation. Switchable attenuation settings. High impedance to ground for both positive and negative sides of the balanced input. Input uses shrouded banana test probe tip. Probe tip accepts large alligator clips and pin-grabber test clips (included). The output to the oscilloscope is a BNC cable with a safety insulated BNC male connector. Optional Universal Power Adapter.
