This function is used to check the loadcell. If it is suspected that the loadcell has been overloaded, the status can
be determined immediately. To do this, place the device in a horizontal position on a flat surface and call up the
main menu page. To enter the DIAGNOSTIC menu, the MENU/ESC button must be pressed. Use the UP or
DOWN button to move the cursor to DIAGNOSTIC and confirm with the ENTER button. You are now on the
DIAGNOSTIC page. Press the ESC key to return to the main menu page.

If the percentage drop is between 5% – 10%, please contact the supplier to have the loadcell replaced. These
values are given as a guide only. The actual need for calibration/replacement of the loadcell varies with its
individual characteristics.

8.6 Select Output

With this option the user data output, RS 232 or USB is selected.
There is an analog output on the device. This generates a signal that goes from +2V to -2V. This signal is a
percentage of the maximum value of the force gauge. FOR EXAMPLE..: FL100 50N is measured in the direction
of pull, then a -1V signal is applied to the analog output. 75N in compression direction, then + 1.5V is present at
the analog output. If the instrument is in PASS – Fail mode, 2V for PASS and 0V for FAIL are present at the analog
output.

Warnings

Incorrectly performed force measurements can lead to serious injury to persons and damage to objects and must
therefore only be performed by trained and experienced personnel.
In particular, it must be avoided that forces act on the purchased measuring an instrument that exceeds the
maximum load (Max) of the instrument or which do not act axially via the external and internal load cell; or if high
impulse forces act on the measuring instrument.

Avoid twisting the loadcell, otherwise, it could be damaged and the measuring accuracy will decrease in any case.

Inappropriate use
Do not use the measuring instrument for medical weighing. If small quantities of the material to be measured are
removed or added, incorrect measurement results may be displayed due to the “stability compensation” in the
measuring instrument! (Example: Slow flow of liquids out of a container suspended from the measuring cell). Do
not apply a continuous load to measuring instruments with an external measuring cell.
Overloads
Please prevent the measuring instrument from being overloaded beyond the specified maximum load (Max),
minus any tare load that may already be present. This can damage the measuring instrument (danger of
breakage!)

Attention:

Make sure that never let people or objects are under the load, as it injures or could be damaged!
The measuring instrument is not suitable for weighing people, do not use it as an infant measuring instrument!
The measuring device does not comply with the German Medical Devices Act (MPG).
Never operate the measuring instrument in rooms where there is a risk of explosion. The standard version is
not explosion-proof.
The design of the measuring instrument must not be changed. This can lead to incorrect measurement results,
safety-related defects, and the destruction of the measuring device.
The measuring instrument may only be operated or maintained by trained personnel.
The measuring instrument may only be used in accordance with the described specifications.
SAUTER must give written approval for any other areas of use/applications.

Warranty

The warranty is void if

Non-compliance with our guidelines of the operating instructions

Use outside the described field of application
Modifying or opening the device
mechanical damage and damage caused by agents such as liquids or liquids have been caused
improper assembly or electrical installation
Overloading the measuring cell

Test equipment monitoring

As part of quality assurance, the metrological characteristics of the measuring instrument and any test weight that
may be present must be checked at regular intervals. The user responsible must define a suitable interval for this
purpose as well as the type and scope of this inspection.
Information on the monitoring of measuring instruments and the necessary test weights is available on the
SAUTER homepage (www.sauter.eu). The weights and measuring instruments can be checked and adjusted
quickly and at favorable prices in KERN’s accredited DAkkS laboratory (traceability to the national standard).
