SECTION VI
6.0 CARE AND MAINTENANCE
Proper care and maintenance should be practiced to maintain long trouble free and accurate
service and to maximize battery life, as follows:
6.1 When not in use, make sure power is off as evidenced by display being extinguished.
6.2 Store sensor head assembly in the fully wound position and store in a dry location.
Do not allow the instrument to remain for long periods in direct sunlight, or store in
temperature above 125° F, or in temperature below freezing. Such temperatures may damage
the liquid crystal display.
6.3 Wipe excess oil or water from tape, and sensor head. Each time the sensor is raised
from the tank, hold the spring loaded tape wiper switch in the “On” position.
6.4 Never permit tape and sensor head to unwind freely (control speed of descent by
usage of a restraining force on crank).
6.5 BATTERY REPLACEMENT (See Approval Label for correct type)
The battery should be replaced whenever the “Lo Bat” symbol appears at the upper
left corner of the display. If the sensor is used to obtain temperature readings when the battery
is low, large errors may result. Always replace battery in a gas free atmosphere. Remove the
six machine screws on the hub cover. Lift the cover with its attached P.C. Board. The battery
is retained within the reel turning drum a spring clip battery holder. Remove the battery from
the battery cap connector. Replace the battery with a fresh battery of the type listed on the
approval label only. Take care to align the viton cover gasket, cover, and machine screw
fasteners when re-assembling to tape reel hub.
