Instruction Manual 
8. Warning 
2.1 Intended use 
The instrument you have acquired serves to determine the 
measuring value of the material to be measured. It is 
intended to be used as a “non-automatic“ instrument, i.e. 
the material to be measured is manually and carefully 
attached at the instrument. The measuring value can be 
read off after a stable measuring value has been obtained. 
2.2 Inappropriate use 
Do not use the instrument for dynamic measuring. In the 
event that small quantities are removed or added to the 
material to be 
measured, incorrect measuring results can be displayed 
due to the “stability compensation“ in the instrument. 
(Example: Slow draining 
off of liquid from a container suspended from the 
instrument). Do not attach a continuous load. This can 
damage the measuring 
unit as well as the parts, relevant to safety. 
Prevent jolts, torsion and oscillation (e.g. by appending 
slopingly) of all kinds. Be sure to prevent overloading the 
instrument in excess of the stated maximum load (max.), 
minus any tare weight that may possibly exist. This could 
damage the instrument (risk of breakage). 
Important: 
• Always make sure that there are no people or materials 
below the load that could be injured or damaged! 
• The instrument is not suitable for measuring people. Do 
not use as baby scales! 
• The instrument does not comply with the medical product 
law (MPG). 
Never operate the instrument in hazardous locations. The 
series design is not explosion-proof. Structural alterations 
may not be 
made to the instrument. This can lead to incorrect 
measuring results, faults concerning safety regulations as 
well as to destruction 
of the instrument. The instrument may only be used in 
compliance with the described guidelines. Varying areas of 
application/ 
planned use must be approved by SAUTER in writing. 
2.3 Guarantee 
The guarantee is not valid following 
• non-observation of our guidelines in the operating 
instructions 
• use outside the described applications 
• alteration to or opening of the device 
• mechanical damage and damage caused by media, 
liquids 
• natural wear and tear 
• inappropriate erection or electric installation 
• overloading of the measuring equipment 
2.4 Monitoring the test substances

Tel: +49 (0) 7431 938 666

FK 
The metrology features of the instrument and any possible 
available adjusting weight must be checked at regular 
intervals within the scope of quality assurance. For this 
purpose, the answerable user must define a suitable 
interval as well as the nature and scope of this check. 
Information is available on 
the home page (www.KERN-sohn.com) with regard to the 
monitoring of instrument test substances and the test 
weights required for this. Test weights and instruments can 
be adjusted quickly and at a reasonable price in KERN’s 
accredited DKD calibration laboratory (return to national 
normal). 
3. Fundamental safety information 
Do not use the hanging instrument to transport loads. 
Prevent jolts, torsion and oscillation (e.g. by appending 
slopingly) of all kinds. 
Never use the hanging instrument over the maximum 
permitted weight (!!Danger of breaking!!). 
Always make sure that there are no living beings or 
materials below the load that could be injured or damaged. 
The hanging electronic instruments from the SAUTER 
instrument are only suitable for hand-held use or use in a 
test stand. 
They are not suitable for hanging from a mechanical hook, 
e.g. a crane hook. 
3.1 Observe the information in the operating instructions 
Please read the operating instructions carefully before 
erecting 
and commissioning, even if you already have experience 
with SAUTER instruments. 
3.2 Staff training 
The device may only be operated and looked after by 
trained members of staff.
