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
°C
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:
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.
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."
