▼ Lower than lower limt
▲ Higher than higher limit

This function allows efficient testing of OK / NOT OK
measurements of similar or identical testing objects.
A lower and an upper limit value can be defined. The
instrument compares the individual m easuring results with
these limit values and shows the OK or NOT OK result by
green or red light diode and by sound.
To set these limit values, please see the SET Menu in
section „Operating keys“.

Baud rate: 9600
Data-Bit: 8

This function allows to eliminate unwanted „Pre-Peak
values“ that are lower than the m ain peak value (Fp). The
“Min limit peak save” value (Fo) takes care, that these
“Pre-Peak values” are not saved.

The „Min limit peak save“ function is only possible in
Peak-Mode.

To set this Min limit value, please see the SET Menu in
section „Operating keys“.

7. Warning

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.

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 measuri ng 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
effected 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.

Guarantee

The guarantee is not valid following

• Non-observation of our guidelines in the operating
instructions

• Alteration to or opening of the device

• Mechanical damage and damage caused by media,
liquids

• Natural wear and tear

• Inappropriate erection or electric installati on

• overloading of the measuring equipment

Monitoring the test substances

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).

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.

Observe the information in the operating instructions
please read the operating instructions carefully before
erecting
and commissioning, even if you already have experience
with S AUTER instruments.

Staff training

The device may only be operated and looked after by
trained members of staff.

Major display deviations (incorrect measuring results) are
possible if electromagnetic fields occur as well as due to
static
charging and instable power supply. It is then necessary to
change the location.

Unpacking

Carefully remove the instrument from its packaging,
remove the plastic wrapping and position the instrument in
its intended working location.
