Contact force sensor calibration - Force
In
case
SV 105AF
transducer
is
connected,
Force
calibration option
becomes available. After entering it, the
instrument will present a list of connected
transducers with contact force sensors.
A typical bathroom scale is sufficient for
contact force sensor calibration.
This calibration should be performed
every time the hand straps are changed.
<ENT>
System Check
allows the user to
compare
force
level
detected
by
SV 105AF against the indication on the
scale it is pressed against. Force level
detected is expressed in kg. In case the
difference between force detected by the
instrument and the one indicated by the
scale at the same time is significant, it is
advised
to
perform
force
sensor
calibration.
<ENT>
After entering the
Calibration
option, user
will be asked to press SV 105AF sensor
with hand straps against a scale so that
this scale indicates between 18 and 20 kg.
<ENT>
Please press the
<ENTER>
push-button
when the scale indicates a value within
the range that instrument asked for. Next
please enter this value indicated by the
scale in the
Enter Force Readout
box.
Please press the
<ENTER>
push-button
to proceed.
In the next steps, instrument will ask to
apply
9-11 kg pressure
and
no pressure
(please put the sensor flat on a surface).
Please follow instructions displayed.
=>
At the end of the contact force sensor calibration procedure the instrument
will switch into displaying the current force applied to the sensor, similarly
as in the
System Check
mode. Please compare displayed values against
those indicated by the scale used for calibration and
Accept

Reject
new
calibration of the contact force sensor. Please note that purpose of the
contact force sensor is to detect the occurrence of contact between hand
and tool and for that purpose it does not need to follow scale’s indications
perfectly.
