Operating instructions
This section will detail how to operate the instrument using front panel keys,
the rotary selector and the LCD display.
One of two green front panel LED indicators, CH1 and CH2, will be
lit, to indicate which channel’s parameters are being changed. The selected
channel can be changed by the front panel key
.
The
A

changed. Initially, it is in the first display line, and the arrow keys and rotary

second line to display the values of other instrument parameters, but those
values cannot be changed unless the
A
indicator is moved to the second line,
e.g. by pressing the
key.
