Disconnect the balance from the wall outlet prior to moving the device.
Avoid condensation damage to the device. When the balance is turned on, condensation
build-up is not possible. If the device is moved from a cool environment to a warm environment, you must allow the device to acclimatize for approx. 2 hours before connecting to the
power supply.
Hazards at the Place of Installation and During Operation
3
Avoid generating static electricity and establish equipotential bonding.
A 10 kOhm ground is used when connecting the balance to the power supply. Disconnecting the ground conductor is not permitted.
3
Exercise caution to avoid glass breakage.
There is a danger of lacerations or cuts caused by sharp edges on glass or metal (contact
springs), particularly when removing or replacing the glass draft shield panels; during cleaning;
if a glass sample container breaks, or when modifying the balance hardware configuration.
3
Models with a separate electronics module (e. g. MSU6.6/3.6/2.7), MSU225S/P
and MSU125P:
Do not mix up the electronics module.
Interchanging with, e. g. models of the ME/SE series will damage the device.
3
Make sure all equipment operators have received proper instructions when working with
hazardous or toxic materials.
Failure to follow correct handling procedures can result in breakage of parts or spillage of
liquids or other substances. Make sure the necessary protective clothing or equipment is
worn, such as protective gloves, clothing, eyewear.
All safety regulations applicable in the laboratory must be observed.
3
Exercise caution to avoid squeezing or crushing fingers when
– Operating the electronic draft shield
– Removing or installing the panels
– Adjusting the display
Do not expose the device to aggressive chemical vapors or to unnecessarily extreme tem-
peratures, moisture, shocks, or vibration.
The device should be set up in areas away from equipment or devices that have strong mag-
netic properties. Extreme electromagnetic fields from electrical lines should also be avoided.
