EN-4 BW SERIES COMPACT BENCH SCALE
2.5 Connecting Power
2.5.1 AC Power
Verify that the intended AC power source matches the AC adapter rating. Unplug* the
rubber access cap underneath the scale, connect the adapter to the power receptacle
through the cut-out, then plug the AC adapter into a power outlet.
* NOTE : When cleaning the scale, turn off the unit, remove the AC adapter and plug
the rubber access cap securely to avoid entry of water inside the scale.
2.5.2 Battery Power
The scale will begin charging with the AC adapter connected accordingly, and auto-
matically switches to battery operation if there is a loss of power. Normal operating
time on a full charge is 50 hours on a 15-hour charge cycle.
Low battery charge is indicated by the flashing LED over the indicator.
AC power or a fully charged battery is indicated by the illuminated LED over the
indicator. A blinking indicates the battery is charging.
NOTES :
• DO NOT continuously charge the scale longer than 24 hours.
• To maximize battery power, the scale can be set up to enter Sleep mode
(only decimal points are displayed) after 2 minutes of inactivity, or auto-
matically turn off after 15 minutes of inactivity (Section 5.2).
• Charging the scale must be performed in a dry environment.
• Plug the rubber access cap to the adapter receptacle to ensure the scale
is protected when operated in a wet environment.
• If the scale is not used within 3 months, recharge and discharge the bat-
tery fully 3 times to maximize the battery condition.
• Dispose of the lead-acid battery according to local laws and regulations.
CAUTION
BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED OHAUS
SERVICE DEALER. RISK OF EXPLOSION CAN OCCUR IF REPLACED
WITH THE WRONG TYPE OR CONNECTED IMPROPERLY.
2.6 Initial Calibration
When the scale is operated for the first time, a Span Calibration is recommended to
ensure accurate weighing results. Before performing the calibration, be sure to have
the appropriate calibration weights. Refer to Section 6 for calibration procedures.
