The
following general information will help you better comprehend the operation
as well as the maintenance of electronic scales. Most scale problems
can be troubleshoot by applying the precautions as described below:
1.
Check the scale batteries (only on models which have batteries). Batteries
are usually the cause of non-working scales. A scale does not weigh
properly when running on low voltage. Regularly replace the scale
batteries with high quality Alkaline Batteries. Take note that
batteries run low when stored for a long time. Many scales returned by
customers have simply dead or low batteries. Try to plug in the adapter
(some Scales come with free Adapter), check if the scale still works. If
yes, your batteries are low and need to be replaced. Please only use the
adapter which was delivered with the scale. Do not use ELANE scales with any
non ELANE supplied AC adapter our wiring is different than most other
consumer products. If you require a replacement adapter, please contact us
we sell cheaper than Dick Smith. If you require replacement batteries for
any of our scales, you can order from us, we are cheaper than retail and our
batteries are always kept refrigerated.
2.
Check the scale temperature. On some higher cost scales we have temperature
compensation in the load cell and electronics which are not much affected by
temperature changes but the following are basic guide lines for any
electronic measurement equipment.
Too high
or too low temperature negatively affects scale performance. Scales
are at their best in room temperature from 65 to 85 degrees Fahrenheit. (18
to 25 Degrees C) If it is cold and its temperature is below 65, the
error tolerance increases. When this happens, the weight may drift.
It increases or decreases noticeably. Scales perform better when in a stable
temperature environment. If you take a scale from one temperature
location to a location with a different temperature plug in the scale with
the adapter and leave it on for about 30 minutes for the scale parts to
reach a temperature equilibrium.
3.
Do not
overload.
Majority of scale errors come from overloading. Each scale has its
rated capacity and all our scales do have mechanical overload protection
which stops the movement of the load cell in case of overload. If the weight
placed on the scale platform is much more than its capacity, the load cell
can be deformed and cause great damage to the scale. All load cells
can be destroyed by overloading. Always take note of this information
when putting your scale anywhere in your bag, back pocket or inside
cabinets.. But a strong hit, we call this a dynamic overload, can still
cause damages to the crystal structure of the load cell. On scale with high
resolution and small capacity, e.g. pocket scales and counting scales,
please do not use your fingers or hand to press on
the platform to estthe scale better add an object such as a pen,
paperclip or small weight to test the function of the scale.
When affixing
the platform on some scales - do not press hard - just place the platform
gently in place.
4.
Do not mishandle. A great number of scale errors come from
mishandling. Scales can be dropped or banged around when transported.
Precision is a major characteristic of scales. Thus, each has its own
set of delicate sensors that can be affected by such pressure due to
mishandling. When trying to mail, ship or transport a scale; be sure
it is packed well and no pressure is on the platform. If you are
shipping the adapter please wrap the adapter in bubble wrap or similar
material so that it will not bang on the scale during shipping.
5.
Put on a flat and stable surface. A scale will not read and weigh accurately
on uneven or unstable ground. This has to be considered greatly when
the scale is calibrated. If a scale is calibrated unstably,
consequently, its readings will all be based on inaccurate information.
Even sound itself contributes to an unstable environment. Sound can
cause vibrations that affect the scale reading. Another source of error is
draft high resolution scales are very sensitive and you can test this by
blowing on the platform so if you operate the scale in any sort of drafts
from aircon, fans or open window you may want to construct some sort of a
windshield or move the scale to another draft free location.
6.
Don operate near electronic devices. Cellular phones, computers and radios
cause electrical disturbances. These are electro magnetic fields,
which may affect scales in varying degrees. Electronic instruments
pick up such interference from up to 15 feet away. This is especially
true with wireless equipment (WIFI) and cellular phones. If you want
to use such electronic devices, they have to be operated at least 10 feet
away from an operating scale.
7.
Calibration. All scales are pre-calibrated at the factory and usually do not
require any calibration. However, each location in the world has a different
ravity- the force the earth is applying to pull the item on the platform. If
you wish to recalibrate the scale to increase your accuracy please refer to
the Calibration instructions on our website and please do not attempt the
calibration unless you have a weight set or the required (sometimes supplied
calibration weight). Exceed model Scales can be remotely calibrated through
our web server.

8. Small
weights and small weight increments due to the nature of digital
processing and automatic Zero software there is a minimum add-on weight
specified otherwise the software will interpret the small add on as a Zero
drift this is similar to mechanical scales where a minimum weight add on is
required to overcome friction. The way around this is to add more by
touching the platform slightly to fool the software into recognizing a
larger weight change and it will settle back to the correct amount once the
additional force is removed. Please note the specifications minimum weight
is usually a little larger than the resolution of the scale, minimum add-on
weight is larger than the resolution of the scale. You can order upon
request a different data chip with the Zero Compensation turned off for a
small fee.
9. Postal
Scale Rate Changes (postage computing scales only) - Postal rates change as
determined by the postal authority. Our scales can be equipped with a new
data-chip which then will update the scales to the latest rates. Some scales
can be updated via the internet. Please check our websites for more
information and instructions.

12.
Quality and Warranty - Our scales sold on eBay maybe new or maybe production
overruns on large orders which we handle for large customers. The scales are
brand new, but may have been repaired off the production line or may
have minor fixes on the circuit board or other nsideparts. This is the
reason we are selling them at 1/3 the normal retail price for the product
and our warranty is as follows:
Pocket
Scales, Fishing Scales
Computer accessories
Postage Computing Scales, PSXXXX Weight Scales,
and ELANE
branded Scales 90 days
Warranty
on Postal Rate Changes: If the Post office changes rates within 90
days of purchase the original buyer qualifies for a free update (chip or
download code) there is however a postage and handling charge for the free
chip.
13.
Returns - We do not accept returns COD or without Authorization
you must request a Return Authorization before shipping the scale back for
repair, warranty or other reasons. If the return is a warranty issue we
cheerfully will refund you postage cost and pay the postage to return the
repaired or exchanged product. Do not return any merchandize to any other
than prescribed address. Do not send any merchandize to our China office the
customs clearance is US$50.00
