Optional Battery Operation
Here are a few notes for those users who ordered the Battery Operation option for the EL-3000:
Before using the scale for the first time, please charge the scale overnight.
The scale’s battery should operate for about 10 hours if left on continuously. Therefore, greater
usage times can be achieved by selecting an appropriate Auto Power Off Period under
A5
of the
User Menu.
The scale can be charged while ON or OFF and can be operated while charging.
To charge the internal battery:
1. Connect the charger (AC Adapter 15 VDC, 800mA) to the scale , then plug the charger into an AC
outlet.
2. After the charging period expires, unplug the charger from the AC outlet, then from the scale. The
scale is now ready for use under its own battery power. If the scale is not allowed for charge for the
full recommended time period, you may notice a decline in the usage period. This is due to the bat-
tery’s reluctance to accept a charge.
Therefore, always charge the scale for at least 10 hours
before using.
3. The charger may be left connected to the scale indefinitely without damage to the internal battery.
When to charge the internal battery:
1. When the scale needs to be charged, the Low Battery Indicator will appear in the lower right-hand
corner of the display. The scale may be used for an additional 15 to 30 minutes without damage to
the internal battery.
If the scale is used for more than 30 minutes after a low battery
indication, permanent damage may occur to the battery and/or the battery may not accept a
charge.
2. With the sealed lead-acid type battery, it is OK to charge the battery at any time to keep the battery
“fresh”. You do not necessarily have to wait for the Low Battery Indication.
NOTE:
When a low battery indication occurs, the scale automatically shuts off after 5 minutes if the
scale is idle. The period selected for Auto Power Off Period (A5) is not altered.
