Thank you for your purchase
of an electronic scale from us.
To enjoy your purchase please take
the time to read this technical guide BEFORE you use the scales
The following general information will
help you better comprehend the operation as well as the maintenance of
electronic scales. Most scale problems can be trouble-shooted by
applying the precautions as described below. Some points may not apply
to your scale in particular.
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. The Glass-top scale has
a battery protector – it needs to be pulled out for the scale to work.
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 “test” the 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 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 is 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’t 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
“gravity” - 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 webserver.

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.
10. Interface - Some scales have a
connector for Interface to the PC – if you wish to connect the scale to
the PC you can purchase this interface cable from us. DO NOT use any
other cable as the wiring is non standard and in some cases some
electronics is inside the cable to facilitate the interface protocol.
11. Lost Manual – You can download
and print a spare manual from our websites -

12. Quality and Warranty - Our
scales sold on ebay may be 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 ”inside” parts. This is the reason
we are selling them at 1/3 the normal retail price for the product and
our warranty is as follows:
Postage Computing Scales, PSXXXX Weight Scales,
ELANE branded Scales 1
year
Warranty on Postal Rate Changes: If the
Postoffice 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
