9. Care and Maintenance
9.1 Care
Clean the instrument of any excess of liquid after
use.
Make sure that the sensing probe is completely
stored in the storage tube after use (reading index
shall indicate less than 420 mm or 1 ft 5 ").
Check the tightness of the reading index screws
and if necessary adjust the level, refer to section
9.9.
Store the instrument in a dry location.
Check periodically (at least every 6 months) the
continuity of grounding by measuring the electrical
resistance between the tape adaptor (or the
sensing probe tube) and the quick connect
coupler. Resistance should not exceed 10

.
Periodically clean carefully the sensor probe, the
frame and the mechanical parts, as storage tube,
tape, with an appropriate solvent.
Note
: always reassemble the storage tube to the
frame in the vertical position to allow the O-ring to
seat properly in the tube.
Check periodically the condition of the tape
cleaner.
With such conductive liquids which form salts
when drying, wash the sensing probe with water or
alcohol and brush it very gently with a soft brush to
prevent a water detection error due to a short-
circuit between the electrode and the tube.
