Function
Switch on Rotating Disk Electrode (RDE).
Application
The RDE is used for direct and stripping determinations with solid
electrodes. Cyclic voltammetry and PSA are also possible with the RDE.
Parameter
Range; Default value / Meaning
Rot.speed
0, 200, 400, ..., 3000 /min; 2000 /min
Rotational speed
Setting of the number of revolutions of the rotating electrode per min.
The set drop time
t.drop
important for certain parameter settings is
0 ms for the RDE by definition.
Description
The
RDE
instruction is used to switch on the rotating disk electrode,
which comprises the 6.1246.000 Drive shaft and the 6.1204.XXX
Electrode tip. A voltage sweep can be carried out at the rotating
electrode.

Comments
•
Within a program, the RDE is not switched off until the
ØSTIR
instruc-
tion or the selection of a different electrode type (
DME
,
SMDE
or
HMDE
).
The RDE is also switched off by
END
in the main program on the
"OP.SEQUENCE" page, but not by
END
in the segment.
•
The RDE can be used for all measurement modes and sweeps.
