BATTERY WARNING
Many Dwyer data loggers contain a lithium battery. Do
not cut the battery open, incinerate, or recharge. Do not heat
lithium batteries above the specifi ed operating temperature.*
Dispose of the battery in accordance with local regulations.
*See the individual specifi cations at www.dwyer-inst.com.
The DLI-T 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, offl oads and LCD display
usage. The DLI-T 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 contact
