Facts About Digital Scale Operation:
The intention of this information is meant to help you in determining the potential cause of an error or a malfunction. If this information helps you in any single way, it has accomplished its goal. We hope you find the information helpful & informative.
Overloading Your Digital Scale:
Overloading your digital scale can,
and probably will, fatally damage your scale. They
are only made to weigh to their maximum rated capacity.
If you place an object on your scale beyond its capacity
you can permanently damage your scale. Be selective
with the objectives you are weighing. All digital
scales can be permanently damaged if you overload
them. The load cell is not made to take the additional
weight. They are made with very sensitive and delicate
Using Inexpensive Batteries & Low Batteries:
We often receive telephone calls with
customers complaining of an inaccurate scale or one
that malfunctions. The number one reason for this
problem is due to weak batteries or battery related
issues. Scales must have a stable power supply or
they will provide you with unstable results. Only
purchase high quality batteries for your scale. If
you do not, then replace the batteries often. Another
issue related to batteries is the connections. Battery
terminals must make a solid connection with your batteries
to operate correctly. Ensure your terminals are connecting
to the battery and not the plastic assembly of the
Your power supply will have a positive
(+), negative (-), and a neutral (o) at its prongs.
These must match with your scales polarization. Basically,
positive terminals must attach to positive terminals
and the same applies for the negative terminals. Simply
because your power supply powers up the scale does
not mean it is the correct power supply. We always
suggest you keep the correct power supply cord with
the scale and label them as a matching pair. Numerous
times, scales do not operate correctly because of
reverse polarization. Simply ensure you are operating
the right scale with the right power supply.
Your Digital Scale Near Electronic Devices:
Electrical disturbances are essentially
magnetic fields. Electronic devices cause these magnetic
disturbances. Scales react strongly toward magnetic
fields. We recommend you do not use your scale near
a computer, monitor, radio, cell phone, or television.
If you place a cell phone near your scale you will
visually see the scale reacting to its field.
Readings By discharging Static Electricity:
Digital Scales can easily become charged
with static electricity. Static electricity is essentially
an electrical charge at rest or an electrical charge
that accumulates on an object when it is rubbed against
another object producing friction. In some working
environments this phenomenon will occur. When it does,
your must discharge it. You may use an anti-static
spray or simply touch the scale and its tray to a
Handling Your Digital Scale:
Scales are precision instruments. They
are made with delicate sensors that can be permanently
damaged by dropping them or crushing them. We always
recommend you keep them in a safe place away from
potential harm. Storing them in the shipping box is
always a logical suggestion. Additionally, mishandling
your scale can separate the LCD (Liquid Crystal Display)
from the PCB (Poly Circuit Board). You may see partial
digits or no digits at all. When this occurs, you
can gently depress on the LCD and reconnect it. In
some cases, you will be required to remove the cover
to reconnect the LCD.
Your Scale On An Uneven Surface:
All scales (whether mechanical or digital)
require a flat stable surface in order to obtain an
accurate result. This is especially true when you
are calibrating your scale. If it has been calibrated
inaccurately, it will only provide you with inaccurate
results. An incorrect calibration will inhibit repeatability.
Always ensure you have a flat surface.
Operating Without First Reading The Instructions:
Digital scales are made with different
programming algorithms. A calibrating procedure for
one scale does not mean it is the same procedure for
another scale. When calibrating a digital scale you
must correctly follow its programming procedure. Often,
we assume a scale has been freshly calibrated when
it has not. Many error messages and calibration errors
can be identified, and eliminated, by simply following
the detailed instruction manual supplied with the
unit. Additionally, if your scale reads to the hundredths
and thousandths place we recommend you become very
familiar with calibration. If your scale has this
level of accuracy we strongly suggest calibrating
your scale each time it is used. This high level of
sensitivity (.001g, .0001g) provides you with highly
refined results so always ensure you are starting
