1 Introduction
Annotation: Please read the remarks in this instruction manual carefully before the
first use, even if you are already experienced with our SAUTER measuring devices.
After receipt of your force gauge, please check the instrument, whether any transport
damages have occurred. Please check, whether the outer packaging, the plastic
housing or any other parts or even the instrument itself have been damaged. If any
damages are determined, please inform SAUTER immediately.
„Sensor outside“means, that the load cell is outside the housing, connected by a
cable with the display unit.
SAUTER offers suitable software and a wide range of accessories optionally. So you
are able to configure your measuring instrument more versatile. Please ask us at
SAUTER or your SAUTER reseller or just visit us on our website www.sauter.eu

BACK LIGHT:
PEAK: (Peak value)
Three functions availa bl e:
- Track mode (continuous measurement)
- Peak mode (capturing max. values)
- Auto-Peak mode, same as Peak-mode, but without the „Minimum limit value“
function
MEMORY: (Memory function)
Memorizes the Peak values to calculate the average value of the measurement
results (see chapter “memorizing Peak values”)
DELETE Function of memorized values (only active in „Memory“ mode)
PRINT: (Print function)
Sends the stored peak values to a PC or Printer (please see chapter 6.1)
High / Low Limit function
LEDs to display OK / NOT OK Tests
▼ Lower than lower limit
● Lights if the STOP value is reached
▲ Higher than highest limit
A lower and an upper limit value can be defined. The instrument compares the
individual measuring results with the preset limit values and shows the OK or NOT
OK result by green or red light diode and by an acoustic sound.
To set these limit values, please see the SET Menu in section „Operation keys“.
Simple Measurement (Track Mode)
Displays (1) the actual operating force and force direction (7) (arrow)
To zero the display, press:
Peak-Hold Funktion (Peak Mode)
To change, please press:

Auto-Peak-Hold-Mode (Auto-Peak Mode)
To change, please press:
Minimum peak limit function to activate storage of measurements
This function allows to eliminate unwanted „Pre-Peak values“ which are lower than
the main peak value (Fp). The pre-setted limit value (Fo) takes care, that those “PrePeak values” are not saved.
The „Min. peak limit value “ function is only possible in Peak-Mode.
To set this Min. limit value, please see the SET Menu in section „Operation keys“.
Storage of Peak limit values and Average value calculation
(out of up to 10 measurement val ues )
Saving Peak values in the instrument
Activation of „AUTO PEAK Function“ by PEAK button
Deactivation of „Average Function“ by MEMORY button
Now, all peak values are stored automatically in the instrument’s memory
To browse through the stored values, please use the ▲ or ▼ keys.
(The values will be shown in the upper display segment)
By pressing the MEMORY key, the average value of the stored peak values can
be displayed (to be seen in the upper display segment)
To delete every stored value, press the▼-key in the AVERAGE-Mode

8 Warnings
Irregular performed force measurements can lead to serious injuries of persons and
damages of objects. Out of this reason, they may only be conducted by trained and
experienced staff.
It has to be avoided, that forces, which are acting on the force gauge, are exceeding
the instrument’s max. load (Max) or forces, which are not acting axially from the
external load cell to the instrument; or, if high impulse forces are acting on the
measuring instrument.
Please avoid any twisting of the load cell. This migh t lead to a breakage and, in any
case, measurement accuracy will decrease.
Inappropriate use
Do not use the instrument for medical measurements. In the case, 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: liquid, slow draining off from a container suspended at the instrument).
Do not leave hanging a continuous load.
Overload
Be sure to prevent overloading the instrument beyond the stated maximum load
(max.), minus any tare weight that may possibly exist. This could damage the
instrument (risk of breakage).
Attention:
- 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 meas ur i ng peopl e. Do not use it as baby scale!
- 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 alteratio ns may not be made to the instrument. This c an l ead to incor r ect
measuring results, faults concerning safety regulations as well as to destruction of
the instrument.
-The instrument may only be operated and maintained by trained staff.
- The instrument may only be used in compliance with the described guidelines.
- Varying ranges of application/ planned use must be approved by SAUTER in
writing.

Guarantee
The guarantee is not valid in following cases:
• Non-observation of our guidelines in the operating instructions
• Use outside the described appli c ati o ns
• Alteration to or opening of the device
• Mechanical damage and damage caused by any kinds of media, e.g. liquids
entering the housing
• Natural wear and tear
• Inappropriate assembly or electric installation
• Overloading of the load cell
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 DAkkS calibration laboratory
(return to national normal) .
Important
Please note the leads of the instruction manual: Please read all instructions carefully
before first use of the instrument, even if you are already experienced with our
SAUTER equ ipment.
