USING THE TARE
Normal Tare
Place a container over the platform. The scale will show its weight. When
pressing the scale will show the “0” value as it will subtract the object’s
weight. Now you can place other objects inside the container, and the display
will show its net weight.
You can find out the total weight (gross weight) by pressing . To visualise
the net weight, press the button again.
The tare weight will be automatically subtracted when the object is removed
from the container.
Note: If there are significant fluctuations in temperature the scale may not show
the value of 0. If that happens press the button to correct the situation.
Maximum tare range: The tare weight cannot exceed the scale’s maximum capacity.
The usable available capacity of the platform is calculated by subtracting the current
tare weight from the maximum capacity. Usable capacity = max.cap - tare.

container. The container’s tare must already be set up.
WEIGHT TEST (CONTROL +/-)
This is a useful function to separate groups of products by weight. It allows
you to discard products that are below a specific weight or exceed it.
The scale shows a bar with a left (negative) side, and a right (positive) side. The
centre indicates accepted products. It also indicates the operation outcome
through three colour lights on the display. When the sample is between the
established limits, the weight is visualised in green. If the sample’s weight
exceeds these limits, its weight is shown in red and vice versa if it’s below the
limit its weight is shown in yellow colour.
The graphic indicates if each product is within the acceptable preprogramed
deviation, if it isn’t the scale will signal an audio warning. The additional
