EB SERIES EN-3

2. INSTALLATION

2.1 Unpacking

Unpack and verify that the following components have been included:

• Scale Unit

• Weighing Platform (plastic base with stainless steel pan)

• Instruction Manual

• AC Adapter
Save the packaging material. This packaging ensures the ideal 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 air currents, vibrations, electromagnetic fields, heat or direct
sunlight.

2.4 Leveling the Scale

Adjust the leveling feet until the bubble is centered in 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 EB 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 display 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 low
battery annunciator on the display (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.

• Replace the battery if it does not charge or hold a full charge.

• Dispose of the lead acid battery according to local laws and regulations.

CAUTION
BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED 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.

6. CALIBRATION

For best results, calibrate the scale at regular intervals. Temperature changes,
gravity variations, altitude changes and abuse are few reasons why a scale may
need recalibration.

When the scale is ideally positioned for operation, enter calibration and proceed as
follows:

Long-press ZERO and COUNT at the same time to initiate
calibration. The required calibration weight flashes on the
display (ex. 3000g).

At this time, a different calibration weight value can be selected by pressing .
Available selections are 1/3, 2/3 and 100% of full capacity.
Once the desired value is displayed, place the corresponding weight on the pan.
The display flashes until the actual weight is registered and the calibration process
ends (the scale re-starts). At this time, remove the weight on the pan before the
display count-down sequence ends.

NOTES:

• Calibration weight is displayed in grams only.

• To abort the calibration process, turn the scale off.

• If needed, the factory default calibration value can be recovered. As the
scale is turned on, press TARE and COUNT at the same time during the power-on
sequence. The power-on sequence will re-cycle and the scale will reinitiate with the
default calibration.

2. INSTALACIÓN

2.1 Desembalaje

Desempaque y verifique que los siguientes componentes han sido incluidos:

• Unidad de báscula

• Plataforma de pesaje (base plástica con bandeja de acero inoxidable)

• Manual de instrucciones

• Adaptador de corriente alterna
Guarde el material de embalaje. Este empaque asegura la protección ideal para
almacenamiento o transporte del producto.

2.2 Instalación de componentes

Posicione las clavijas de la plataforma de pesaje en los agujeros pasantes en la
parte superior de la caja, luego coloque la plataforma en su lugar. Asegure el forro
en uso con una cinta adhesiva de doble lado según se necesite.

IMPORTANTE:

• Antes de utilizar la báscula, remueva el tornillo de protección de
embalaje localizado debajo de la báscula. Este tornillo asegura la

protección de la celda de carga durante el transporte, pero necesita
ser removido de la báscula para operarla adecuadamente.

• Se recomienda que el tornillo protector sea reinstalado si transporta la
báscula. No lo apriete demasiado ya que puede dañar la celda de carga.
Para reinstalar, encienda la báscula y coloque un peso de 500 g sobre
la bandeja, luego apriete lentamente el tornillo hasta que la pantalla
muestre un valor entre 250 g y 400 g.

2.3 Selección del emplazamiento

Opere la báscula sobre una superficie firme y nivelada. Evite ubicaciones con
cambios rápidos de temperatura, corrientes de aire excesivas, vibraciones, campos
electromagnéticos, calor o luz solar directa.

2.4 Nivelación de la báscula

Ajuste la pata de nivelación hasta que la burbuja esté centrada en el círculo del
indicador de nivel (ubicado en el panel frontal).

NOTA: Asegúrese de que la báscula esté nivelada cada vez que cambie su ubicación.

2.5 Conexión a la fuente de corriente

2.5.1 Corriente alterna

Verifique que la fuente de corriente alterna propuesta coincida con la clasificación
del adaptador de corriente alterna. Conecte el adaptador de corriente alterna
suministrado a la toma de corriente debajo de la báscula. Enchufe el adaptador

de corriente alterna a un tomacorriente con un polo a tierra adecuado.

2.5.2 Suministro de corriente con baterías

La batería comenzará a cargar con el adaptador de corriente alterna conectado. Un
indicador LED en la parte inferior derecha de la pantalla muestra el estado de carga
de la batería:

• Verde – la batería está totalmente cargada

• Amarillo – la batería tiene una carga parcial y está cargándose

• Rojo – la batería está casi descargada
Cuando la corriente alterna no esté disponible, la báscula operará con la batería

recargable interna. La báscula también cambiará automáticamente a la operación
con baterías si existe una falla en la corriente o el cable de corriente es desconectado.
La carga baja de batería es indicada por el indicador de batería baja en la pantalla
(la báscula operará durante aproximadamente 10 horas más antes de apagarse
automáticamente).

Antes de utilizar la báscula por primera vez, la batería recargable interna debe ser
cargada totalmente hasta por 12 horas. Una batería cargada totalmente puede operar
la báscula durante aproximadamente 80 horas sin corriente alterna. La báscula
puede ser operada durante el proceso de carga. La batería está protegida contra

sobrecargas y la báscula puede permanecer conectada a la línea de corriente alterna.
NOTAS:

• La batería debe ser recargada cada tres meses si la báscula no es
utilizada durante un periodo prolongado

• Reemplace la batería si no carga o mantiene una carga completa

• Deseche la batería de plomo-ácido de acuerdo con las leyes y
regulaciones locales.

PRECAUCIÓN
LA BATERÍA DEBE SER REEMPLAZADA SOLAMENTE POR UN
DISTRIBUIDOR DE MANTENIMIENTO AUTORIZADO. EXISTE EL
RIESGO DE EXPLOSIÓN SI ES REEMPLAZADA CON EL TIPO

EQUIVOCADO O CONECTADA INADECUADAMENTE.

2.6 Calibración inicial

Cuando la báscula sea operada por primera vez, se recomienda un intervalo
de calibración para asegurar resultados exactos de pesaje. Antes de realizar la
calibración, asegúrese de que tiene los pesos de calibración adecuados.
