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 cation sheets at www.Dwyer-inst.com.

The DLI2 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 DLI2 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 batteries, locate and remove the four(4) 9/64” hex screws on the back of the unit. Separate the halves and the battery compartment is now visible. Remove the old AA batteries from the battery holder and replace with six(6) new AA alkaline batteries as indicated on the holder. When replacing the cover, make sure that the gasket is still seated in its groove, and that all wires are tucked away inside the compartment.

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
