BATTERY INFORMATION
Replacement
We recommend that you replace the baery annually, or prior to logging crical data. Only use 3.6V ⅔AA lithium metal baeries.
The data logger does not lose its stored readings when the baery is discharged or replaced; however, the data logging process will
stop and will not resume unl the baery is replaced and the logger restarted by EL-WIN-USB or an EL-DataPad.
Only use an EL-USB-1-PRO baery that is supplied or recommended by Lascar, which is rated for use in high temperatures and has
the correct baery terminals. Using non-recommended baeries may result in re or explosion at high temperatures. Suitable
baeries are: Tadiran TLH-5955/S and Tadiran SL-561/S.
Please note that leaving the data logger plugged into the USB port for extended periods will cause some of the baery capacity to
be lost.
Passivaon
If le unused for extended periods of me the lithium metal baeries, including those used in the EasyLog range of data loggers,
naturally form a non-conducve internal layer prevenng them from self-discharge and eecvely increasing their shelf life. When
rst installed in the data logger, this may cause a momentary drop in the baery voltage (the Transient Minimum Voltage) as
the internal layer is broken down, resulng in the data logger reseng. Inserng the baeries in the data logger and leaving it
connected to a PC for about 30 seconds will remove this layer. Aer this, remove and re-install the baeries to reset the data
logger. Overall baery life will not be aected.
WARNING
Handle lithium metal baeries carefully, observe warnings on baery casing. Dispose of in accordance with local regulaons.
ADVISORY INFORMATION
Due to the weight of the EL-USB-1-PRO, a USB extension cable is recommended for connecon to the USB port of the PC to reduce
strain on the USB connecon.
