1.1 Important
Instructions
Ambient Conditions
The
KERN 770, GS
and
GJ
balances are designed to
provide reliable weighing results under normal ambient
conditions in the laboratory and in industry. When choosing
a location to set up your balance, observe the following so
that you will be able to work with added speed and
accuracy:
- Set up the balance on a stable, even surface (benchtop
or floor);
- Avoid placing the balance in close proximity to a heater
or otherwise exposing the balance to extreme heat or to
direct sunlight;
- Protect the balance from drafts that come from open
windows and doors;
- Avoid exposing the balance to extreme vibrations during
weighing;
- Protect the balance from aggressive chemical vapours;
- Do
not
operate the balance in a hazardous
area/location.
Do not expose the balance to extreme moisture over long
periods. Moisture in the air can condense on the surface of
a cold balance whenever it is brought to a substantially
warmer place. If you transfer the balance to a warmer area,
make sure to condition it for about 2 hours at room
temperature, leaving it unplugged from AC power.
Afterwards, if you keep the balance connected to AC power,
the continuous positive difference in temperature between
the inside of the balance and the outside will practically rule
out the effects of moisture condensation.
Do avoid electric and magnetic fields around the balance.
Do check the balance with test weights at least once a day.
Balance’s opening causes invalidity of warranty !
