Front Panel Buttons
Go ahead and press any front panel button. The instrument always provides an audible
response to each button press. Valid entries yield a short beep; incorrect entries yield a
longer beep. Don’t worry if you press an inappropriate button and get a long beep; you
can’t damage the instrument. It will discard the button entry and wait for another entry.
Selecting a Channel
The channel number appears in the right display. Press
G or D to select a channel. You
can change the channel when in Inactive Mode, when looking at data in the Review
array, or when the Monitor function is on.
