The PA-677 current probe enables a general purpose oscilloscope to display AC and DC current signals up to 70 A Peak (50A RMS). The PA-677 current probe can also make AC and DC measurements with a multimeter by using the recommended accessory (BNC-to-banana) plug adapter.


  • High sensitivity of 2mA
  • Wide AC bandwidth up to 1MHz
  • Low noise (about 1/3 lower than competitors)
  • Dual power: AC adaptor for indoor, batteries for outdoor applications
  • Detachable output wire — convenient for packing, storing and self examination for any damages
