Percentage Operation
The EL 3000 Digital Scale contains a percentage operation which is useful for such applications as
filling, check weighing and moisture determination.
The total weight of the item being sampled determines the resolution of the percentage readout. For
example, if the sample weight is greater than or equal to 10,000 external scale divisions, the scale will
discern 0.01% increments. See table below more information.
To use the percentage operation:
1. Toggle
the
MODE
key until the scale is in “%” mode. If there is no previous sample entered, the
scale will respond with the following display indication. If the following message does not appear,
press the
SAMPLE
key once.
This display indication is prompting you to
place 100% of the sample on the platform all
at once.

4. Press
the
SAMPLE
key. If the sample weight is over the required sample weight, the scale will now
show the sample as being 100%. If not, a “Lo” message will flash briefly, prompting you for a
heavier sample. See table below for more information.
Percentage Operation Sample Weight Guide:
The minimum sample weight is 100 scale graduations. This will allow the scale to discern 1 part in 100.
To get a higher resolution, use 1,000 or even 10,000 times the scale’s graduations as your sample
weight. Below are three examples to help determine the best sample weight for your application.
