PERIODIC MAINTENANCE
Inspect electrode and cable. The cable used for
connection to the instrument must be intact and there
must be no points of broken insulation on the cable or
cracks on the electrode stem or bulb. Connectors must
be perfectly clean and dry. If any scratches or cracks
are present, replace the electrode. Rinse off any salt
deposits with water.
CLEANING PROCEDURE
Soak in
AD7061
general cleaning solution for approximately
30 minutes.
IMPORTANT:
After performing any of the cleaning
procedures, rinse the electrode thoroughly with
AD7000
,
refill the reference chamber with fresh electrolyte and
soak the electrode in
AD70300
storage solution for at
least 1 hour before taking measurements.
