2 Basic 
instructions 
2.1 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 material to be 
weighed is manually and carefully suspended. As soon as a 
stable weighing value is reached the weighing value can be 
read. 
2.2 Improper 
Use 
Do not use balance for dynamic weighings. In the event that 
small quantities are removed or added to the material to be 
weighed, incorrect weighing results can be displayed due to the 
“stability compensation“ in the balance. (Example: Slowly drain-
ing fluids from a container suspended on the balance.) No 
permanent load must remain on the balance. This may dam-
age the measuring system. 
Impacts and overloading exceeding the stated maximum load 
(max) of the balance, minus a possibly existing tare load, must 
be strictly avoided. Balance may be damaged by this (danger 
of breaking). 
 
Caution:  
Ö  Make sure that never persons or objects are under the 
load which could be injuried or damaged! 
Ö  The balance is not suitable for weighing persons! 
Ö  The balance does not correspond to the law of medical 
products (MPG). 
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 incorrect 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. 
2.3 Warranty 
Warranty claims shall be voided in case  
 
• 
Our conditions in the operation manual are ignored 
• 
The appliance is used outside the described uses 
• 
The appliance is modified or opened, 
mechanical damage and damage caused by media, liquids 
• 
Natural wear and tear 
• 
The appliance is improperly set up or incorrectly electri-
cally connected 
• 
The measuring system is overloaded 
2.4 
Monitoring of Test Resources 
In the framework of quality assurance the measuring-related 
properties of the balance and, if applicable, the testing weight, 
must be checked regularly. The responsible user must define a 
suitable interval as well as type and scope of this test. Informa-
tion is available on KERN’s home page (www.kern-sohn.com) 
with regard to the monitoring of balance test substances and 
the test weights required for this. In KERN’s accredited DKD 
calibration laboratory test weights and balances may be cali-
brated (return to the national standard) fast and at moderate 
cost. 
Basic Safety Precautions 
Ö  Do not use the suspended balance for conveying loads 
Ö  Never exceed the maximum permitted load (!!Danger of 
breaking!!). 
Ö  Always ensure that there are no persons, animals or 
objects that might be damaged underneath the load. 
Ö  Avoid any kind of shock, torsion and oscillating (e.g. 
caused by inclined suspending)
