## .. RDE ..... Rot.speed ......../min

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.
