PA-677 Current Probe

Max. DC A Current: ± 70A DC. Max. AC A Peak: 140A p-p. Max. AC A RMS: 50Arms. Frequency Range: DC to 1MHz (-3dB). Max. Sensitivity: 2mA. Battery Type: 9V.

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.

Features

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
