2 INSTALLATION
2.1 Unpacking
Unpack and verify that the following components have been included:
; EC Scale
; Weighing Platform (plastic base with stainless steel pan)
; Instruction Manual
; AC Adapter
Save the packaging material. This packaging ensures the best possible protection
for the storage or transport of the product.
2.2 Installing Components
Position the weighing platform pins into the through-holes on the top housing, then
set the platform securely into place. Secure the in-use cover with double-sided tape
as needed.
IMPORTANT:
; BEFORE USING THE SCALE, REMOVE THE SHIPPING PROTECTION SCREW
located underneath the scale. This screw ensures protection of the load cell
during transport, but will need to be removed for the scale to operate properly.
; It is recommended that the protective screw be re-installed if transporting the
scale. Do not over-tighten the protective screw as it may damage the load cell.
To re-install, turn the scale on and place a 500g weight on the pan, then
slowly screw in the protection screw until the display shows a value between
250g to 400g.
2.3 Selecting the Location
Operate the scale on a firm, level surface. Avoid locations with rapid temperature
changes, excessive dust, moisture, air currents, vibrations, electromagnetic fields,
heat or direct sunlight.
2.4 Leveling the Scale
Adjust the leveling feet until the bubble is centeredin the circle of the level indicator
(located on the front panel).
NOTE: Ensure that the scale is level each time its location is changed.

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

2 INSTALACIÓN
2.1 Desembalaje
Desempaque y verifique que los siguientes componentes hayan sido incluidos:
; Báscula EC
; Plataforma de Pesaje (base plástica con plato de acero inoxidable)
; Manual de Instrucciones
; Adaptador de CA
Guarde el material de empaque. Este empaque asegura la mejor protección posible
para el almacenamiento o el transporte del producto.
2.2 Instalación de los componentes
Posicione los pines de la plataforma de pesaje en los agujeros en la parte superior
de la caja, entonces coloque la plataforma de una forma segura en su lugar.
Asegure en-utilizan la cubierta con la cinta de doble cara según lo necesitado.
IMPORTANTE:
; ANTES DE UTILIZAR LA BÁSCULA, QUITE EL TORNILLO DE PROTECCIÓN PARA
EMBARQUE localizado debajo de la báscula. Este tornillo asegura la protección
de la celda de carga durante el transporte pero necesitará ser removido de la
báscula para operarla apropiadamente.
; Se recomienda volver a instalar el tornillo de protección si se va a transportar
la báscula. No apretar demasiado éste tornillo ya que puede dañar la celda
de carga. Para volver a instalarlo, encienda la báscula y coloque un peso de
500 g sobre la bandeja; después, lentamente, introduzca el tornillo de protección
hasta que el lector indique un valor entre 250 g y 400 g.
2.3 Selección de la ubicación
Opere la báscula sobre una superficie firme y nivelada. Evite lugares con cambios
bruscos de temperatura, exceso de polvo, humedad, corrientes de aire, vibraciones,
campos electromagnéticos, calor o la exposición directa a la luz solar.
2.4 Nivelación de la báscula
Ajuste las patas de nivelación hasta que la burbuja esté centrada en el círculo del
indicador de nivelación (localizado en el tablero frontal).
NOTA: Asegúrese de que la báscula está nivelada cada vez que cambie su ubicación.

2.5 Conexión a la red eléctrica
2.5.1 Alimentación CA
Verifique que la fuente de alimentación eléctrica CA coincide con la clasificación
del adaptador CA. Conecte el adaptador CA suministrado a la toma de alimentación
debajo de la báscula. Conecte el adaptador CA al tomacorriente con una puesta a
tierra adecuada.
2.5.2 Alimentación con baterías
La batería comenzará a cargarse con el adaptador de CA conectado. Un indicador
LED en la parte inferior derecha de la ventana de Recuento muestra el estado de
carga de la batería:
• Verde – la batería está cargada completamente
• Amarillo – la batería esta parcialmente cargada y está cargándose
• Rojo – la batería está casi agotada
Cuando la alimentación CA no está disponible, la báscula operará con la batería
recargable interna. La báscula cambiará automáticamente a la operación con
baterías si existe una falla en el suministro eléctrico o si se desconecta el cable de
alimentación. La carga baja de la batería es indicada por el anunciador
báscula operará durante aproximadamente 10 horas más antes de apagarse
automáticamente).
Antes de utilizar la báscula por primera vez, la batería recargable interna debe
cargarse completamente hasta por 12 horas. Una batería cargada completamente
puede operar la báscula durante aproximadamente 80 horas independiente de la
alimentación CA. La báscula puede operar durante el proceso de carga. La batería
está protegida contra la sobrecarga y la báscula puede permanecer conectada a
la línea de alimentación CA.
