right-hand ones select that at the CH2 connector. Each output may be set to one of
the following settings:-
X %
When set to X % the corresponding rear panel CH1/CH2 connector will output a
voltage related to the X %fs front panel display as follows:-
X %fs CH1/2 Voltage

+100 10.0 V
0 0.0 V
-100 -10.0 V
-120 -12.0 V
Y %
When set to Y % the corresponding rear panel CH1/CH2 connector will output a
voltage related to the Y %fs front panel display as follows:-
Y %fs CH1/2 Voltage
