Section 9: Maintenance

BATTERY WARNING

Most Dwyer data loggers contain a lithium battery. Do
not cut the battery open, incinerate, or recharge. Do not heat
lithium batteries above the specified operating temperature.*
Dispose of the battery in accordance with local regulations.

*See the individual specification sheets at www.dwyer-inst.com.

The DLI-H does not have any user-serviceable parts except the battery
which should be replaced periodically. The battery life is affected by
battery type, ambient temperature, sample rate, sensor selection, offloads
and LCD display usage. The DLI-H has a battery status indicator on the
LCD display. If the battery indication is low, or if the device seems to be
inoperable, it is recommended that the battery be changed.

To change the battery, locate and remove the four (4) 3/32 hex screws on
the back of the unit. Separate the halves and the battery compartment is
now visible. Remove the old 9V battery from the battery clips and replace
with a new 9V battery. Dwyer recommends using 9V lithium battery. An
alkaline battery is acceptable, but will yield a shorter battery life.

For any other maintenance or calibration issues, Dwyer recommends the
unit be returned to the factory for service. Before returning the device,
you must obtain an RGA from the factory. For further information, please
