D4008 – EN EZ 2810 Operators Manual 3
Thank you for your purchase of a Digi-Star EZ2810 scale indicator. Your
EZ2810 is the culmination of more than 30 years of agricultural weighing
engineering and expertise. With proper operation and preventative
maintenance, the EZ2810 will last for many years.
The Digi-Star EZ2810 is primarily designed for weighing agricultural animal
feed products during the loading and unloading of mobile and stationary feed
mixers. The EZ2810 can also be used on feed delivery boxes, forage
wagons, grain carts, and animal scales.
The EZ2810 is not for use with applications for which the EZ2810 is not
intended, or as outlined in this manual.
Use of the EZ2810 outside of its intended purposes may result in inaccurate
weight measurement or damage to instrument.
All rights reserved. Reproduction of any part of this manual in any form whatsoever without Digi-Star’s
express written permission is forbidden. The contents of this manual are subject to change without notice. All
efforts have been made to assure the accuracy of the contents of this manual. However, should any errors be

0.2.0 EZ2810 Special Features
Preset Weight
The EZ2810 indicator provides simple to use and very useful Preset Weight feature. Using the
numeric keypad, the operator can enter the desired weight of product that the operator wants to
load or unload. Once loading or unloading begins the EZ2810 will count down to 0 (zero). As the
weight approaches 0 the audio and visual alarms will begin to pulse with the frequency of the pulses
increasing the closer the preset weight gets to 0. At 0 the alarm light and buzzer will sound
continuously. See section 2.2.0 for details.
Rotation Counter / Timer
The Rotation Counter / Timer provides the useful benefit of monitoring mix revolutions or mix time
and a warning light, buzzer, or external signal will indicate when the desired mix revolutions or time
has been achieved. For this the EZ2810 uses an optional Rotation Counter Sensor which is fitted to
the drive line of the feed mixer. See section 2.9.2 for details.
Maintenance Message
The Maintenance Message is available with the Machine Hour Meter function noted above and
provides the ability for the equipment manufacturer or equipment owner to utilize the EZ2810 to
display a specific Service or Maintenance message after a predetermined period of operation
similar to a Change Oil message in an automobile. See section 2.9.5 for details.
Machine Hour Meter
The EZ2810 when fitted with the Rotation Counter Sensor can be configured to record hours of
operation. The Machine Hour Meter can provide valuable information to aid the user in determining
when maintenance and upkeep is required. See section 2.9.6 for details.
Bluetooth FEED App
The Topcon FEED App is a smart phone application that communicates via Bluetooth with select
Digi-Star scale models equipped with Bluetooth hardware. The App provides Cab Control and
feeding functionality, as well as Scale Tracker support.

0.3.0 Accuracy Statement
READ THIS SECTION BEFORE USING THE SCALE SYSTEM
Digi-Star Scale Systems are designed and manufactured to provide the greatest accuracy possible.
However proper installation and use are required in order to obtain the highest level of accuracy.
When using the scale system, the following must be considered in order to realize the best possible
performance and accuracy.
 Load cells must be installed with the proper orientation. Most Digi-Star load cells have a label
indicating either the “TOP” or bending direction of the load cell. Inspect load cells to determine if
the load cells are installed correctly. Incorrect installation of load cells will result in inaccurate
measurement.
 Load cells should not be subjected to any strains or loads other than the weight of the load.
Stress or strain caused by misalignment or other factors when accurate weight readings are
desired will negatively affect the accuracy.
 The weighing unit should be stationary with minimum movement, and on a level surface, to
ensure that weight readings are as accurate as possible.
o The effect of movement on accuracy depends on the speed and roughness of the
ground and application. Rougher terrain and faster and/or greater movement increases
the degradation of accuracy.
A level surface is defined as being less than a 5” (13cm) change in rise over 10’ (3.0m) of run. As
the slope of the terrain increases, degradation of accuracy will also increase.
