Tensiometer’s preliminary manual - TSS V1 r. 4 dtd 06/02/06
-15-
The TSS transducer is a measuring instrument that can be damaged when the measuring probe [9] is
subject to excessive or anomalous loads, like torsions or other loads that are not corresponding to
the normal use of the unit when measuring warp tensioning.
When using the measurement system always consider wire dimensions. This measurement system
can measure with a variety of different type of wires, with an intrinsic flexibility that allow them to
be deviated by the measurement probe [9] from their natural running plane.
It is to be remembered that friction may influence the quality of the measurement performed by the
instrument.
The system has been calibrated using a cotton wire with an indicative diameter, when compressed,
of 0,2 mm, keeping the TSS transducer in movement toward the wires, so to consider the friction
effect in these conditions.
The measurement system has been calibrated by tensioning the wires at 2000 grams; this load is to
be considered as the full scale of the TSS transducer. In the transducer there is a load limiter,
active with loads higher than the nominal full scale.
Considered that this measurement system is directly applied on a small amount of the total height of
the warp, it is possible that its measurement differs from the one performed by other measurement
systems eventually installed on the machine, based on the measurement of the tensioning of the
total width of the warp (these measurement conditions are different and measurement is affected by
this different context).

Pitagora display instrument
6.1
Pitagora LCD display
In order to avoid damages to the pushbuttons it is recommended to press as needed, without
exaggerating with the applied force and without using sharpened objects (like screwdrivers)
that may damage the membrane of the instrument.
The displayed measure is expressed in grams.
6.2
Display
The LCD display of the Pitagora instrument (no backlight) supplies the following information:
1.
Main display
, 7 alphanumeric digits, 8 segments plus sign, able to display measurements up
to ± 9999999 or characters and words (capital or lower letter as needed the text readable)
2.
Secondary display
a 14 alphanumeric digits, used to display indications concerning the
current measurement on pre primary display or to indicate auxiliary indications during the
customization / calibration of the instrument
3.
Bar display
, with central zero position, to indicate the trend of the measured value.
