3. Basic Information (General)
3.1. Proper use
The balance you purchased is intended to determine the weighing value of material
to be weighed. It is intended to be used as a “non-automatic“ balance, i.e. the ma-
terial to be weighed is manually and carefully placed in the centre of the weighing
plate. As soon as a stable weighing value is reached the weighing value can be read.
3.2. Improper Use
Do not use balance for dynamic weighings. In the event that small quantities are re-
moved or added to the material to be weighed, incorrect weighing results can be dis-
played due to the “stability compensation“ in the balance. (Example: Slowly draining
fluids from a container on the balance.)
Do not leave permanent load on the weighing plate. This may damage the measur-
ing system. Impacts and overloading exceeding the stated maximum load (max) of
the balance, minus a possibly existing tare load, must be strictly avoided. This could
cause damage to the balance.
Never operate balance in explosive environment. The serial version is not explosion
protected. The structure of the balance may not be modified. This may lead to incor-
rect weighing results, safety-related faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.
The appliance may only be opened by trained service technicians according to
KERN standards.
Before opening, disconnect appliance from power supply!
