mV-MEASUREMENT
Metal electrodes (Pt, Ag, Au): Metal electrodes are always ready for use.
During short interruptions they are immersed in distilled water. They
should be cleaned regularly:
∗ Silver electrodes are immersed in a concentrated ammonia solution
during one hour.
∗ Platinum or gold electrodes are immersed in concentrated nitric acid
during one hour.
1.
Select the mV range by pressing MODE (see 'Channels' page 4).
2.
After rinsing the electrodes with distilled water, immerse them in the
solution to be measured and read the display.
3.
Rinse the electrodes always with distilled water after use and store
them in a 3...4 M KCl solution.
