Press
At this time the scale adjusts the Zero/Balance to
maintain the gross weight displayed. Small
changes in weight can occur while moving the
scale system to new locations for loading or
unloading. This change us called "zero shift" and
is due to several factors including terrain changes
and mechanical stresses.

3. Mounting and connection
INDICATOR MOUNTING
LOAD CELL CONNECTION
The indicator is easily attached to the
Indicator Mounting Bracket by hooking the
top over the plate and securing the bottom
with two (2) bolts (size# 10 x 24 x 3/4") and
nuts.
The indicator is designed to operate with
strain gage load cells. The system will
normally be supplied with a “J-BOX” cable
going between the indicator and the load cell
junction box. Extension Kits are available
from your dealer in various lengths.
To connect the load cells, attach the junction
box cable to the J902 connector on the
bottom panel of the scale. Connect the load
cell cables to the junction box as shown
below.
POWER CONNECTION
Warning!
Always disconnect the indicator power cord
before “jump starting” or fast charging a
battery.
Disconnect all indicator leads before
welding on equipment. Failure to do so can
cause surges which will damage the scale.
The power cable should be connected
directly to a vehicle battery or regulated
power supply. The scale end of the power
cable is attached to the J901 connector
located on the bottom panel of the scale.
Connect the RED wire from the power
cable to +12VDC and the BLACK wire to
GROUND. The indicator is fused
internally at 4 amps.

Additional protection can be achieved with

Please call (920) 563-9700 and request
Digi-Star Form F3050.
Warning!
This indicator was calibrated at the factory
to weigh accurately with your system.
Additional calibration is not necessary under
normal conditions.

The Short Form Setup & Calibration
procedure allows you to change the
“SETUP” and “CAL” numbers of the
indicator. You may want to perform this
procedure if;
1. The indicator is being connected to
different load cells, or
2. You want to adjust the calibration to
match another scale system.
Before continuing, first write down the
current SETUP and CAL numbers of your EZ
indicator. These numbers are displayed
during the Self Test.
To run the self test:
With the indicator already ON, press the
key to start the Self Test. Press the

Do not attempt to calibrate the scale if
the indicator is not reading stable weights.

4. Adjusting indicator to match another scale
4. Adjusting indicator to match another scale
Sometimes two different scales are used to
weigh the same load. When this is done,
the weight measured by each scale may not
be the same. This can be caused by one or
both of the two scales being slightly out of
calibration. This indicator has the ability
to match any other scale, even if that scale
is not calibrated.
Scale Information sheet
To match your EZ scale (Scale A) to
another scale (Scale B) you must determine
the Calibration Multiplier. To do this,
place a load on Scale A (feed wagon, etc...)
and write down the weight displayed.
Repeat several times to determine the
average weight. Next, place the same load
on Scale B and again write down the
weight displayed.
