867 pH Module
4 Operation and maintenance
4.1 General notes
4.1.1 Care
The 867 pH Module requires appropriate care. Excess contamination of
the instrument may result in functional disruptions and a reduction in the
lifetime of the otherwise sturdy mechanics and electronics.
Spilled chemicals and solvents should be removed immediately. Above all,
the plug connections on the rear of the instrument (in particular the
power socket) should be protected from contamination.
CAUTION
Although this is largely prevented by design measures, the power plug
should be unplugged immediately if aggressive media have found their
way into the interior of the instrument to prevent serious damage to
the instrument electronics. In such cases, Metrohm Service must be
informed.
4.1.2 Maintenance by Metrohm Service
Maintenance of the 867 pH Module is best carried out as part of annual
service, which is performed by specialist personnel from Metrohm. A
shorter maintenance interval may be necessary if you frequently work with
caustic and corrosive chemicals.
Metrohm Service provides professional technical consultation at all times
for the maintenance and servicing of all Metrohm instruments.
