OPERATION MANUAL 3
1. Introduction
The FG series force gauges are designed for measuring pressure or pulling force in
laboratory, manufacturing and quality control applications.
The gauge can be held in hand or mounted on a stand (using the four threaded
holes at the bottom of the enclosure).
The R 232C serial connector allows the measurement results to be transmitted to a
computer or a printer for further analysis or recording.
2. Set
The basic set includes the following elements:
1. Force gauge,
2. Push tips – 4 pcs, 1 hook tip, 1 extension piece
3. Power supply unit ~230 V 50 Hz / =12 V; 1.25 A,
5. K-1 cord (dynamometer – computer),
6. K-1 cable,
7. CD containing an operation manual and software,
8. Warranty.

4 OPERATION MANUAL
3. Safety instructions
Read carefully the safety instructions included below.
Observe these instructions to avoid electrocution or
damage to the force gauge itself or other devices
connected to the force gauge.
• Repairs and any necessary adjustments may only be conducted by
qualified personnel.
• Do not use the force gauge when any part of the enclosure has been
removed.
• Do not use the force gauge in potentially explosive atmospheres.
• Do not use the force gauge in areas with a high humidity.
• In the case of suspected damage to the force gauge, turn off the gauge and
do not use it until it is examined by a specialised servicing facility.
4. Rules for handling a worn force gauge
According to the applicable regulations on the
protection of the environment, do not put worn
electronic devices in containers for common waste.
• When put out of operation, a worn force gauge can be delivered to bodies
authorised to collect old electronic equipment or to the point of purchase.

OPERATION MANUAL 7
7. Preparing the force gauge for operation
1. Take the gauge out of the case.
2. Fit a measurement tip suitable for the measurements to be conducted on the
gauge plunger.
Intended use of the individual tips:
- tip A – measurement of surface pressure force,
- tip B – measurement of point pressure force,
- tip C – measurement of pressure on an axis or an edge,
- tip D – measurement of edge pressure force,
- tip E – hook for measuring pull force or suspending and weighing an object,
- tip F – extension piece suitable for all types of above-mentioned tips.
If the force gauge has been transported from an area with low
temperature to an area with a higher temperature, e.g. during
winter, water may condensate on the gauge’s enclosure. In such a
case, do not turn on the gauge’s power supply, as it may lead to
damage to the gauge or improper operation. Before turning on the
gauge, leave it for 1 hour to acclimatise.

8 OPERATION MANUAL
8. General rules for use
1. When conducting measurements by hand, make sure that the direction of the
measured force is identical with the gauge’s axis (axis of the gauge plunger).
Otherwise, only a component force along the gauge’s axis will be measured.
2. The gauge allows for resetting in the entire measurement range (this operation is
called taring in the case of measuring the mass) by pressing the → T(0) ← key.
Resetting/taring does not extend the measurement range but only subtracts the
entered reference value from the measured value.
3. The measurement mechanism is a precision device and is sensitive to shocks and
vibrations. It is not allowed to hit the measurement tip against any objects.
4. Do not overload the gauge above the maximum overload value (20%).
When transporting the force gauge, unscrew the measurement tip and
put the gauge in the case to protect it against accidental pressure on
the gauge plunger.

OPERATION MANUAL 9
9. Turning on the gauge
Place the gauge in the operating
position, e.g. horizontal position (by
laying it on a table). Turn on the
gauge by pressing the
ON/OFF key.
When necessary, plug the gauge’s
power supply unit to a ~230 V/50 Hz
socket and connect the power supply
unit’s plug to the gauge’s 12 V
socket.
The gauge automatically tests the
electronic subassemblies and then
resets. During this operation, the
gauge should remain stationary and
its sensor should not be affected by
any forces.
After the resetting has been
successfully completed, the gauge
indicates zero.
Unsuccessful resetting is signalled by
an appropriate message.
Note
It is possible to accelerate the resetting process by pressing the
MENU key, which
will recall the results from the previous resetting.
If the batteries are low, leave the gauge’s external power supply unit ON until they
are fully recharged. The batteries’ charge level is signalled by an indicator in the
upper section of the display.

10 OPERATION MANUAL
10. Description of measurement methods
The gauge can be used to measure pressure and pull forces. In addition, when
mounted properly, it can be used as suspension scales to measure the mass.
10.1 Measuring actual and peak value of a pressure/pull force
Measuring pressure force Measuring pull force
Before starting the measurement,
choose a suitable measurement tip,
screw it to the gauge plunger and
reset the gauge in the operating
position, e.g. horizontal position
(laying the gauge on a table). The
resetting process starts automatically
after turning on the gauge or by
pressing the →T(0)← key.
To perform the measurement,
indicate the force direction using an
arrow in the display’s lower bar
section and “+” (pressure) or “-” (pull
force) symbol.
To change the measurement from the
actual value (continuous
measurement) to the maximum value
(peak measurement), use the PEAK
key.
When measuring a force whose
direction changes, the gauge
indicates the value of the force
exerted in the direction in which the
maximum value was last exceeded.

OPERATION MANUAL 11
10.2 Measurement of the mass – using the gauge as scales
When using an additional element (bowl, basket, etc.) for suspending an object to
be weighed, the gauge can be used to measure the mass. In the case of
measurements which do not require a high level of precision, the gauge can be
hand-held. To ensure maximum precision of the measurement, the gauge should be
mounted on a stand using the four threaded holes at the bottom of the enclosure or
it can be suspended using a special suspension element (option available on
request).
ince the value of the gravity force used to calculate the mass depends on the
gravitational acceleration in the location where the gauge is used, the device is
calibrated for a specific value of the gravitational acceleration. The factory preset
value is the gravitational acceleration in Gdańsk ( g
R
= 9.81415 m/s
2
). In the case of
significant differences, see the value applicable for the gauge’s shipment address.
When transporting the gauge to a location where the gravitational acceleration
differs significantly, recalibrate the gauge.
The values of the gravitational acceleration for some of the Polish cities are
presented in the table below.
