1 Introduction
Thank you for choosing the SAUTER FL series instrument. With correct use and
regular re-calibration it will give many years of accurate and reliable service.
The FL can measure tensile and compressive forces accurately, being simply used
by the operator. It may be used handheld or mounted on a fixture or test stand.
SAUTER offers software and accessories to make the force gauge even more
versatile. Ask your SAUTER distributor for additional information or visit our website
at www.sauter.eu
2 Before Use
After having received the unit please check that no physical damage has occurred to
the packaging material, plastic case or the instrument itself. If any damage is evident,
please notify SAUTER immediately.
3 Operation Overview
The most common used features (such as displaying force, peak hold, zero and
changing of displayed units) can all be done by pressing a single dedicated key
identified on the front panel-see the Basic Functions section.
You can press a menu key to access the gauge configuration- see the Main Menu
section.
The FL is supplied with a set of 4 Nickel Metal Hydride AAA rechargeable batteries.
For safety reasons during transportation the batteries are shipped discharged. To
obtain maximum battery life we recommend that you charge them with the
charger/adaptor supplied for at least 14-16 hours when you first receive the
instrument.

Figure 1
To power up the gauge, the ON/OFF key has to be pressed. A short self-test will start
during which the capacity in Newton will be shown.
After the self test, providing no load has been applied to the instrument, the display
will show all zeroes. This is because the gauge re-zeroes itself during the self-test
routine.
*If a force is applied via the load cell sensor (hole at the bottom of the FL), the
reading on display will register the applied force.
*Forces may not show zero if it is moved during the self test routine. Once it is
properly mounted and zeroed, the reading will be stable.
*Do not overload the load sensor. This will cause irreparable damage. Forces
greater than 120% of full-scale will produce an audible beep and OL symbol will blink
on the display until load is release and RESET key is pressed.
To power down the gauge press the ON/OFF key.
*All the current settings are saved when the gauge is turned off and the gauge will
function in the same mode when powered up again.
8 Basic Functions
Tensile forces are displayed on the FL and recognized by the symbol. Compressive
forces are displayed on the FL and recognized by the symbol.
Display of Tension/Compression

A load indicator bar alerts the operator to how much load has been applied to the
load sensor.
For tensile force the indicator bar is moving from right to left. For compressive forces
the indicator bar is moving from left to right.
Zeroing the gauge
During the operation of the gauge it is often necessary to zero the display – e.g.
when you wish to tare out the weight of a grip, so it does not become part of the
measured reading. Press and release the ZERO key.
Reversible display
The display can be turned about 180°. The following has to be done:
When the gauge is turned off, the button “Menu/Esc” has to be pressed and held. In
addition, the button “On/Off” has to be pressed and the gauge will turn on and like
this, the display reversion has been performed.

10 Measurement Practice
For best measurement accuracy, keep the compression/tension forces in line with
the force gauge. Alleviate bending loads and torque loads applied to the load cell as
these can adversely affect measurement performance.
Always keep the gauge below the capacity limit shown on the front of the gauge. If
the gauge is used above this capacity in either tension or compression, even for a
short time, permanent load cell damage can result. An overload damage will not be
covered by warranty.
