Installation
Ambient Conditions
Sartorius QC scales are designed to provide reliable
weighing and counting results under normal ambient
conditions encountered in industrial environments.
When choosing a location to set up your scale,
observe the following so that you will be able to work
with added speed and accuracy:
– Set up the scale on an even, stable surface (table or floor)
– Avoid extreme heat radiation from heaters
or direct sunlight
– Protect the scale from drafts that come through open
doors and windows
– Avoid areas that may subject the scale to extreme
vibrations during weighing
– Protect the scale from aggressive chemical vapors
The scale may not be used in hazardous
areas/locations where there is danger of explosion.
Do not expose the scale to extreme moisture over long
periods of time. Moisture in the air can condense on
the surfaces of a cold scale whenever it is brought to
a substantially warmer place. If you transfer the scale 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 scale connected to
AC power, the constant positive difference in
temperature between the inside of the scale and the
outside will practically rule out moisture condensation.
Note for QC Models Verifiable for Use in Legal Metrology:
The scale can be adapted to your individual require-
ments through simple changes to code settings in the
scale operating menu. For more information, see the
section entitled “Scale Operating Menu.”
Preparing the Scale for Verification as a Legal
Measuring Instrument in the EU*:
After initially connecting the scale to the power
supply (or after a relatively long power outage),
allow the scale to warm up for at least 24 hours.
