Acoustic Fluid Logger - Maintenance
Charging the battery
The Acoustic Fluid Logger unit requires a minimum of maintenance. Batteries should be charged
regularly after each day’s use, using the wall-mount charger sold that accompanies the unit. Simply insert
the round, yellow end of the charger cable over the charger port on the logger’s front panel, and tighten
the black thumb ring. Then plug the other end of the charger into a standard 110-volt wall outlet.
(Adapters for 220 power are available as an optional accessory.) Usually an overnight charge will be
sufficient.
Note: Keep the power switch in the off position during charging.
Occasionally, a damaged battery will need to be replaced. Instructions follow in the maintenance
section of this manual for changing a battery. It is absolutely necessary to use caution not to damage the
internal circuit boards or cut the internal wiring cables while changing a battery. Prior to replacing the
battery, however, efforts should be made to charge the unit with the accompanying battery charger for at
least 24 hours.
Note: When storing the Acoustic Fluid Logger, always make sure the power switch is
turned off, to avoid running down the battery.
Loading thermal paper
Thermal paper rolls must be replaced as they are consumed. The thermal printer built into the
Acoustic Fluid Logger will operate for many years without maintenance if used with the thermal paper
supplied with the unit and stocked by Sage Technologies. Common office paper rolls can damage the
print head, and should be expressly avoided.
Most important: Thermal paper must be loaded into the machine properly, as it is coated on one
side only, and the paper will not print properly if loaded improperly .
To load paper, hold the paper in your left hand, with the paper tail coming
off the bottom of the roll and pull the tape out to the right with your right
hand. Drop the roll of paper into the printer paper carriage in the top of the
Acoustic Fluid Logger. Take the end of the paper and tear it off straight
across.
Feed the paper under the silver bar, and on top of the black platen roller.
Push the silver platen tab (on the front panel of the logger) to the right
while feeding paper to the platen. Turn on the unit, and the paper should
feed automatically. Use the silver-tab platen release to advance or
straighten the paper manually.
