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.

a restraining force on crank).

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 reading 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 by 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 casket, and
machine screw fasteners when re-assembling to tape reel hub.
