EN-4 EC Series
2.5 Connecting Power
2.5.1 AC Power
Verify that the intended AC power source matches the AC adapter rating. Connect
the supplied AC adapter to the power input receptacle underneath the scale. Plug
the AC adapter into a properly grounded power outlet.
2.5.2 Battery Power
The battery will begin charging with the AC adapter connected accordingly. An LED
indicator below and to the right of the Count window shows the status of battery
charging:
• Green – battery is fully charged
• Yellow – battery is partially charged and charging
• Red – battery is nearly discharged
When AC power is not available, the scale will operate on the internal rechargeable
battery. The scale will automatically switch to battery operation if there is a power
failure or the power cord is removed. Low battery charge is indicated by the
annunciator (the scale will operate for approximately 10 hours more before
automatically switching off).
Before using the scale for the first time, the internal rechargeable battery should be
fully charged for up to 12 hours. A fully charged battery can operate the scale for
approximately 80 hours independent of AC power. The scale can be operated
during the charging process. The battery is protected against overcharging and
the scale can remain connected to the AC power line.
NOTES:
; The battery must be recharged every 3 months if the scale is not used for a long
time.
; 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 Span Calibration procedures.
