Fundamental information (general)
2.1
Intended use
The balance you have acquired serves to determine the weigh-
ing value of the 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 attached at the balance. The
weighing value can be read off after a stable weighing value
has been obtained.
2.2
Inappropriate use
Do not use the balance for dynamic weighing. 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: Slow drain-
ing off of liquid from a container suspended from the balance)
Do not attach a continuous load. This can damage the measur-
ing unit as well as the parts, relevant to safety.
Prevent jolts, torsion and oscillation (e.g. by appending slop-
ingly) of all kinds. Be sure to prevent overloading the balance
in excess of the stated maximum load (max.), minus any tare
weight that may possibly exist. This could damage the balance
(risk of breakage).
Important:
• Always make sure that there are no people or materi-
als below the load that could be injured or damaged!
• The balance is not suitable for weighing people. Do
not use as baby scales!
• The balance does not comply with the medical prod-
uct law (MPG).
Never operate the balance in hazardous locations. The series
design is not explosion-proof. Structural alterations may not be
made to the balance. This can lead to incorrect weighing re-
sults, faults concerning safety regulations as well as to destruc-
tion of the balance. The balance may only be used in compli-
ance with the described guidelines. Varying areas of applica-
tion/planned use must be approved by KERN 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
The metrology features of the balance and any possible avail-
able 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
KERN's home page (www.kern-sohn.com) with regard to the
monitoring of balance test substances and the test weights
required for this. Test weights and balances can be adjusted
quickly and at a reasonable price in KERN's accredited DKD
calibration laboratory (return to national normal).

Fundamental safety information
Do not use the hanging balance to transport loads.
Prevent jolts, torsion and oscillation (e.g. by appending
slopingly) of all kinds.
Never use the hanging balance 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 dam-
aged.
The hanging electronic balances from the KERN CH
series are only suitable for hand-held use (see photo).
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
KERN balances.
3.2 Staff training
The device may only be operated and looked after by trained
members of staff.
