2.2.2 Changing parameters
To set or change a numerical parameter in the channel menu the respective line is
selected with the cursor:
Example: U
BIA
1 is to be changed:
CH4 I1=+ 0.1234nA
1 CG P1= 0.12345nW
2 CG U
BIA
1= 0.00 V
CHANGE
Pressing the key (
CHANGE),
activates the tuning knob enabling the selected
parameter to be changed. If the selected parameter is a switch parameter (i.e. the
polarity of the photo diode) the function of the soft key will change:
TOGGLE:Polarity PD1
Pressing the right soft key will toggle the polarity.
Pressing
terminates the input.
NOTE
Some parameters can not be changed, as they are measurement values
(i.e. the photo diode current) or may not be changed during bias voltage
switched on. In these cases access is denied indicated by a long beep.
