Operation

Your indicator is probably
defective. Try another
indicator to verify.
NOTE : Be aware of
electrical interference
that might affect your
scale such as: mobile
phones, CB radios, radio
towers, electrical motors,
etc. Also make sure load
cell cables are not tie
strapped to hydraulic lines
or the hydraulic reservoir.

Does indicator come on?

Is reading on indicator
stable?

Defective Indicator: If you suspect
a bad indicator, the easiest way to
check is to try another indicator.
Even if indicator is a different model,
or is set-up for a different scale, it at
least should come on.

Poor Connection: Poor
connections can be tricky. If in
doubt, don’t just tighten connection,
take them apart and clean them first.
Any connection with rust or paint
should be sanded or wire brushed.

Weak Battery: If you suspect
battery, try replacing it with another
one. Don’t be fooled if using a
voltmeter to test your battery. A
weak battery may test good if
checked when there is no load on
the battery.

Defective Power Cord: Make
sure the power cord’s red wire is
connected to the plus (+) positive
side of battery, and the black (-)
negative wire is connected to the
negative side of battery. If using
a multimeter to check for voltage,
measure between pin 1 (pos) and
pin 2 (neg). The meter should read
between 10.5 and 14.5 volts DC.
If using a tractor power cord, the
black wire on the tractor power cord
is positive and the white wire is
negative.

Stand on, or hang your
weight over each load
cell. Does indicator
respond to your weight
when you stand or
hang on scale?

Does scale weigh you
correctly with your
weight over any of the
load cells?
NOTE: Are readings
all positive? If not, load
cell is upside down.

Does the scale weigh
you approximately

the

same over all 3 load
cells?

No

Check j-box and all
load cell cables for cuts
or pinched/flat spots.

Remove the cover from j-box.

Is there moisture in j-box?

Yes

No

Dry out your j-box.

Look for loose connections.
If you watch indicator display
while moving around the
wires inside the j-box, and by
pressing on the j-box printed
circuit board, you will see if
there is a loose connection or
poor solder joint.

The indicator is
probably not set up and
calibrated correctly.
Check decal on bottom
of indicator. The decal
shows for what type of
load cells the indicator
was calibrated. By
pressing the “on” key
while the indicator is
already on, you will get
the indicator’s “set-up”
and “cal” numbers.
Write these down and
see if they compare
to the set-up and
calibration numbers on
the indicator. Contact
your dealer for further
information.

If display is unstable, or
flashes “±”, disconnect
j-box cable from
indicator. Is display still
unstable?
