VII.- OPERATION'S DESCRIPTION
HOW TO WEIGHT A PRODUCT
Turn your scale on pressing the key. At this moment the scale is ready to weight.
Then place the product to weight on the plate and you will see the weight in the alphanumeric
display. The “kg” symbol will appear in the display. For example, if you place a product whose
weight is 3 kg, you will see the following
HOW TO USE THE "TARE" (KEYPAD/FOOTSWITCH)
When you wish to weight a product in a container and you do not want to consider the container's
weight during the operation, you can use the “tare” function. To use this function, follow these steps:
suppose you are going to weight 5 kg of some product in a container that weight 10 kg.
1.- Place the empty container on the scale.
2.- Press the key or the footswitch. Then the display will show:
Note: if the weight displayed on the display is changing the tare function cann’t be enabled.
3.- Put the product inside the container and the scale shows only the weight of the product without
the container's weight. Note: when you remove the container a negative number (weight of
container) appears in the display
It is important to mention that this function is subtractive. For example, if we have a container that
weight 1 kg, the scale will only be able to weight up to 1 kg of product to complete the maximum
capacity (3 kilograms in a l-eq 4 model).to cancel the tare function just press the key or the
footswitch and the scale will return to the normal function. The tare symbol will disappear
The two following observations are specially important.
A) when there is no weight on the scale (container) you can not activate the "tare" function.
B) when a container is "tared", but when you remove it from the plate and you remove a larger
weight than the container, (grease, remaining of a product, etc.), or when the plate is slightly
lifted with your hand. "neg" (negative) will appear.

ENGLISH
12
When this happens :
A) Let go the plate if you are holding it.
B) If the message continue, turn off the scale and turn it on again.
HOW TO USE THE "REFERENCE TO ZERO"
It is possible for the scale to show a number in the display without having any product on the plate
due to voltage variations, rough handling, or some other factor. When this happens, simply press
the key and the view finder will return to "zero". The word "zero" will appear in the display. This
operation is commonly known as "resetting to zero".
HOW TO USE THE KEY
When you do not have enough light you can use the backlight to improve the readability of the data
on display. To turn on and turn off the backlight just press the key.
HOW TO USE ALARM FUNCTION
Press the key, it’ll be display “hi lmt?” In the display
Then press or keys for set high alarm limit.
Press key for increment or key for decrement value, if key still pressed the increment /
decrement will be faster. For save high alarm value and go to adjust low alarm value press . I’ll
be display “lo lmt?” In the display.
Then press or keys for set low alarm limit.
[ Key for increment or key for decrement value, if key still pressed the increment /
decrement will be faster]. For save low alarm value press . The scale it’ll be ready to weight.
Note: for disable alarm, make the same procedure but set high and low alarm to zero (0.000)
HOW TO DISPLAY ALARM LIMITS

USE OF THE BATTERY
The scale can operate with an ac/dc power supply, or with a battery ( 6 volt included). The battery is
rechargeable using the ac/dc power supply and the procedure is the following.
recharge: to make this operation, just connect the scale to the ac/dc power supply for a period of
time approximate to 10 hours with the scale turned off. The energy stored in the battery during a
recharge can last up to 100 hours of continuos operation. When you recharge the battery for some
hours, but the battery can not get enough charge to turn on the scale, then you must change the
battery by a new one. In this case you can contact to your authorized distributor.

CHARGE AND DISCHARGE CYCLES
SERVICE LIFE IN RELATION TO CHARGE/DISCHARGE CYCLES
The charging capacity of the rechargeable battery in this scale decreases according to the number of
charge/discharge cycles,this causes that the service life is reduced to 1000 cycles. For this reason
the warranty period for the battery is limited to six months after the purchase date of the scale.
"LOW BATTERY" INDICATOR
If the battery does not have enough energy to keep the scale operating for a long time, a low
battery indicator appears in the view finder. This is the first warning signal indicating that it is
necessary to recharge the battery.
ç
Even with this signal, it is possible for the scale to keep on operating for a short period of time (30
minutes), but after a second warning signal appears ("low bat") in the display, the scale stops itself
and does not respond to the instructions.
To eliminate any of the two indicators and continue using the scale without any concern, connect the
ac/dc power supply to the scale. And remember to recharge the battery.
