5.5 Storage and Maintenance
• Method of storage
Care is required when storing the SC72 meter. To maintain the SC72 meter in good
condition, observe the following:
(1) After measurement, thoroughly wash the sensor in water.
(2) Leave the sensor connected to the meter body, to protect the connector from
staining. Connector contamination could affect connector leakage resistance and
thus conductivity reading accuracy, or affect the waterproofing afforded by the O-
ring.
(3) Do not place any object on top of the sensor or on the top of SC72 meter.
• Storage location
When the SC72 meter is not being used, store it in a safe place. If it is to be stored for a
long time, store it:
* In a dry place (low humidity) at normal temperatures.
* Out of direct sunshine.
* Do not store it in a corrosive gas atmosphere.
* In a location free from water condensation.
• Replacing O-rings or gaskets
Gaskets for the battery box and O-rings for sensor connections can be replaced. If they
are very dirty or damaged, replace them with new ones.
CAUTION
When installing O-rings and gaskets, clean them and their mounting surface with a cloth
moistened with alcohol so that they are free from dirt. Otherwise, water resistance may
not be assured.
