7. Press the MENU key.
8. Select Calculations and select Rel, then Acquire.
Cabling could be as high as ≈ 300 pF, which could prevent full-scale verification due to the large
cable capacitance offset. Cable lengths should be minimized to reduce cable capacitance as much
as possible.
9. Connect the shielded banana cable to the 1 nF to 1 µF Decade Capacitance Box as shown in the
figure below.
