1M
Channel 2's input impedance is now set to 50 .
The "arrow" keys can also be used to toggle the state of toggle keys
(DC/AC, 50 /1M , etc.) as indicated by the flashing indicator within the
arrow keys. However, for simplicity in this procedure, use the
corresponding toggle key to change states.
If you want to change the input impedance back to the default
1 M impedance, perform the following step.
