2. TRANSPORT AND STORAGE
2.1. Packaging
Retain all elements of balance packaging in case they are needed for future
balance transporting. Only an original balance packaging can be used for
transporting a balance. Before packaging, disconnect all cables and conductors from
the balance and remove any moveable parts from the weighing chamber (weighing
pan, shields, inserts). Balance components should be packed into their original
packaging for their proper protecting against possible damage during transport.
3. UNPACKING, INSTALLATION AND COMMISSIONING
3.1. Installation and place of use
− Balance should be stored and used in rooms free from any vibrations and
shocks, with no air movement and undusted,
− Ambient air temperature in a weighing room should not exceed the range
specified on balance data plate. Temperature changes should be of laminar
structure, and permissible temperature change ratio should not exceed 0,5
°
C/h
− Air humidity should contain within 35% - 80%; maximum humidity change rate
5% / h,
− A balance should be placed on a wall console or a stable workbench, free
from vibrations and distant from heat sources,
− Pay special attention to weighing magnetic materials. In case such loads are
to be weighed, use the option of under-hook weighing. The hook for
assembling an under-hook weighing kit is located in the balance base,
− In case static electricity may have effect on balance indications, ground the
balance using the grounding bolt located at the back side of balance base.
− A microbalance MYA 5/3Y/F1 series is intended to determine mass of filters
with maximum diameter of 160mm.
The material of the tested sample is highly electrostatic, thus it requires
applying special measures protecting against static electricity. In case of
carrying out a weighing process in low humidity conditions, it is advisable to
use an additional air ionizer. Such a large surface of the weighed object, in
case of materials like paper that is highly hygroscopic, causes occurrence of
weighing error of several hundreds of reading intervals. Thus it is highly
important to ensure required ambient conditions for balance operation (such
as those listed in the product folder):
