5.6. Input Connections
(See Figure 2)
Look at the bottom and the right of the Oscilloscope. The Oscilloscope has seven signal inputs: two safety
BNC jack inputs (CH1 and CH2) for scope measurements, four safety 4-mm banana jack inputs for Multimeter
R, V and A measurements,
Isolated input allows independent floating measurements between Multimeters and Scopes.
