Installation Instructions
Your balance is designed to provide reliable weighing results
under normal ambient conditions. 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
– Avoid placing the balance in close proximity to a heater or
otherwise exposing the balance to heat or direct sunlight
– Protect the balance from drafts that come from open
windows or doors
– Avoid exposing the balance to extreme vibrations during
weighing
– Protect the balance from aggressive chemical vapors
– Do not expose the balance to extreme moisture over long
periods
Conditioning the Balance:
Moisture in the air can condense on the surfaces of a cold
balance whenever it is brought into 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.
