Precision
Scale PCE-LS Series (Legal For Trade / Class II)

The
verifiable precision scale comes in two models (LS-500 and
LS-3000). The back-lit, high-contrast graphic display of this
precision scale leads the user safely through the process;
lengthy instructions and operator errors are a thing of the
past. All LS models can be calibrated / adjusted automatically
at the touch of a key, at a pre-set time, or triggered by
temperature changes. Without the need to handle expensive
external weights, these functions support integration in
quality management systems. The large weighing platform of the
scale is a real added plus for weighing larger objects.
The integrated RS-232-interface enables you (by using the optional software-kit) to automatically send the weighing data into a sequence table.
LS Series of precision scales have been designed to meet the
applications of laboratories, schools, universities, industry
and commercial users, without the high cost implications
usually found with this type of scale. This

have available to meet your requirements. |

In the upper image a
PCE-LS 500 series analytical scale with a round
weighing pan with 120 mm diameter is shown.
The lower image shows a PCE-LS 300 series
analytical scale with a square weighing pan (165
x165 mm). Both weighing pans have been made with
stainless steel and can be used for all kind of
laboratory issues, production and research.

Data sheet
Apart from the digital reading of the weighing
data and the large graphic LCD display, this
analytical scale comes with a range strip (0 ...100 %)
to check the used range directly. Besides, you
will adjust both the intensity and the back
light through the keypad. The upper image shows
the display of the analytical scale with the
back light off.

A verified analytical
scale is recommended to be used to
prepare medicines in pharmacies as well as for
the analysis in medical and pharmaceutical
laboratories. So, it is important to bear in
mind the scale usage scope. If you wish, a
calibration can be carried out by PCE-Group.
An official verification is required when the
analytical scale is used for:
a) Trade relations when the price of the
product is determined by its weight.
b)
Preparation of medicines in pharmacies as well
as for the analysis in medical and
pharmaceutical laboratories.
c)
Determination of rates, tariffs and official
fines as well as for official and
objective surveys in judgements.
d)
Manufacturing of packages.
Every analytical scale is checked by the
official authorized centre to provide it with a
verification certificate. Besides, precision is
determined within the permitted tolerance
framework. EU Verification is valid for all the
countries members of the EU (European Union). |

Calibration of the Counting scale
Calibration:
To meet with the UE 90 / 384 / EWG
standard, all counting scales must be officially
calibrated to be used for:
a) Trade relations when the price of
the product is determined by its weight.
b)
Preparation of medicines in pharmacies as well as
for the analysis in medical and pharmaceutical
laboratories.
c) Determination of rates,
tariffs and official fines as well as for official
and objective surveys in judgments.
d)
Manufacturing of packages.
Every scale can be checked by the official
authorized centre to provide it with a
Calibration certificate. Besides, precision is
determined within the permitted tolerance
framework. EU calibration is valid for all the
countries members of the EU (European Union).
Scale calibration with CAL adjusting program:
The adjusting program is marked with an official
mark once calibration has been carried out.
Calibration will be valid for the given
location. So, it is necessary to provide with
the location of the scales by means of the
postal code to prepare calibration. Calibration
can be performed in the company or in the
location of the scale depending on the scale.
Calibration of a scale with adjustment of
automatic change: There are not any
limitations depending on the location of the
scale due to the fact that the automatic
adjustment can be used after a calibration has
been done, i.e. it is not sealed. In this case,
calibration will not depend on location.
Calibration value: measurement of
calibration tolerance which is nearly ever
between 1
and
10 d.
