Display for magnetic band
Installation
Before installing the instrument, read the following warnings:
a) Connect the instrument strictly following the instructions of the manual.
b) It is the responsibility of the user to check, before using, the correct settings of the parameters of the
instrument to avoid damage to persons or things.
c) The instrument CANNOT function in a dangerous environment (inflammable or explosive).
d)
The unit has sensible parts to electrostatic charge, therefore the handling of the inner electronic
cards has to be carried out with appropriate care to avoid permanent damages.
Description
F20 is a dimension-display with integrated position sensor to be combined to the magnetic band P25, in order
to carry out a complete device for measuring linear or angular shiftings.
The LCD display concurs the visualizzazione from -9999999 to +9999999 with a resolution of 0,1.
It is possible to select the count direction, the position of the decimal point, and the measure unit (mm, inches
ore degrees).
The displayed value may be correct through a programmable multiplicative factor with values ranging from
0,000001 to 9999999.
The dimension display may be carried out either in absolute or in incremental mode by simply pressing the
suitable key; this allows relative measuring within the measuring field. It is also possible to set a preset
dimension that may be recalled through the suitable key.
There are also available 5 distinct origins for the correction of quota by using different tools and the offset
function for balancing of tool wear. On the display all activated functions are showed by a symbol. The keys
enabling to recall the preset dimension and the absolute/relative dimension switches may be inhibited in a
very simply way.
On the display all activated functions are showed by a symbol.
The power supply is internal with 4 batteries type AA (LR6) of 1,5V, two-year-life
The run-down of battery is indicated with occasional blinking, 1 month before the complete flat the indication
remains on; the battery has to be changed, in very easy way and without loosing quota, while the machine is
standing.
Magnetic strip mounting
The magnetic strip P25 consists of a magnetized plastic ferrite strip with alternate magnetic poles of 2,5 mm
pitch, carried by a ferromagnetic steel strip. Mechanical protection of the plastic ferrite strip is supplied by a
non magnetic steel strip with thickness 0,2mm.
The magnetic strip is assembled by sticking it with a bi-adhesive tape. The surface has to be smooth, clean
and dry: is advisable to clean it with a degreasing product (isopropyl alcohol, ethyl alcohol, solvents, etc). The
magnetic strip has to be stuck holding the plastic ferrite side in the direction of the sensor, which means the
steel side leaned on the stand surface. Fixed the magnetic strip, to keep off damages due to abrasions or
grazes of the plastic ferrite strip, is advisable the appliance (always bi-adhesive) of the non magnetic
protection strip.
The optimal ambient temperature for stick the bi-adhesive tape is over 10°C. The maximum adherence of
the tape works out after 48 hours (about) of the application and is kept between –10 and 80°C.
