3.1 Electrodes

MME

MME stands for Multi-Mode Electrode and is the working elec-
trode commonly used in the 797 VA Computrace stand. It combi-
nes the most important polarographic and voltammetric mercury
electrodes in a single construction:
DME

Dropping mercury electrode

SMDE

Static mercury drop electrode

HMDE

Hanging mercury drop electrode

For installation and maintenance of the Multi-Mode Electrode, see
Hardware Manual.

DME

DME is an electrode mode of the Multi-Mode Electrode and stands
for Dropping Mercury Electrode. It is the classical mercury
electrode where the mercury flows out freely from the glass capil-
lary until the mercury drop is knocked off by a tapping mechanism
