Switch on/off current measurement. If switched

on, the set Potential is applied to the electrodes

and the current is measured continuously. This

mode is indicated by the red light beside the

<Cell> button.

Potential (V) [ -5...+5 V ; 0 V ]

Voltage to be applied to the electrodes.

Potential (V) [ read only ]

Display of current voltage applied to the electro-

des.

Current (xA) [ read only ]

Display of measured current.

No electrode No electrode connected to the 797 VA Compu-

trace stand. This setting is useful for changing the

electrode at the stand.

DME Selection of the Dropping Mercury Electrode

(DME).

SMDE Selection of the Static Mercury Drop Electrode

(SMDE).

HMDE Selection of the Hanging Mercury Drop Electrode

(HMDE).

RDE/SSE Selection of the Rotating Disk electrode (RDE).

Switch on/off inert gas purging.

Tests the electrodes (see Check the MME, section

8.10).

Note: Occasional electrode tests should be done

in this sector and not with the “GLP Wizard” (not

to overwrite GLP data).

Switch on/off stirrer/RDE with the set RDE/Stirrer

speed

RDE/Stirrer speed (rpm) [ 0...3000 rpm ; 2000 rpm ]

Revolutions per minute of the stirrer/RDE.

DME: Switch on free dropping at the MME.

SMDE: Dropping in intervals of ca. 1 s at the

MME.

HMDE: Formation of a new single mercury drop

at the MME .
