2. BASIC INFORMATION
2.1. Intended use
The purchased balance serves to determine the weighing value of loads in
laboratory environment. It is intended for application as a non-automatic
weighing instrument only, i.e. the material to be weighed is manually and
carefully placed in the center of the weighing pan. Weighing result should be
read only after stable reading has been obtained.
2.2. Inappropriate use
Do not use the balance as a dynamic weighing instrument. Even if small
quantities of weighed material are added or removed from the weighing pan of
the instrument, the reading should be taken only after stabilization of the
measurement result. Do not place any magnetic materials on the weighing pan,
as this can cause damage of the measuring system of the instrument. Be sure
to avoid impact shock and overloading the balance in excess of the prescribed
maximum measuring range (max capacity), minus any possible tare weight that
has been applied. Never use the balance in an environment endangered by an
explosion. This balance has not been adjusted for operation in explosive areas.
There must not be any modification made to the balance.
2.3. Warranty
Warranty is not valid at the following:
• Non-observation of the guidelines of this user manual,
• Use of balance other than specified in this manual,
• Alternation to or opening of the device,
• Mechanical damage and damage caused by media, natural water,
and tear,
• Inappropriate assembling or defects of electric installation,
• Overloading of the measuring instrument.
10
2.4. Monitoring the metrological parameters of the instrument
Metrological characteristics of the balance requires periodical inspection
carried out by its operator. Inspection frequency is conditioned by ambient
conditions in which the balance is used, types of performed processes and
accepted quality management system in an organization.
2.5. Data included in this user manual
Please read the user manual carefully before assembling and startup, even if
the user is experienced with this type of weighing instruments.
2.6. Staff training

7. START-UP
When plugged to mains, the balance displays name and number of software, and
afterwards proceeds to weighing mode.
7.1 Balance temperature stabilization period
Before start of measuring processes, it is necessary to wait until the balance is
thermally stabilized. It is a period of so called balance self-heating. In case of
balances PS series self-heating period takes approximately 30 minutes. The
specified time interval refers to balances that have been stored in room temperature
before plugging to mains.
For balances that were stored in much lower temperatures before plugging to mains
(e.g. during winter period) thermal stabilization should last approximately 4 hours.
Correct operation of a balance is possible within temperature range specified in the
technical parameters, see point 1. If the balance is placed in area which ambient
temperature is out of temperature range specified in the technical data, then
balance’s display may signal such situation by lighting an appropriate marker (a
black triangle).
In case the balance displays the marker, increase or decrease ambient
temperature, depending on present temperature value. It is recommended that
ambient temperature changes at balance’s place of use are very small (slow).
