Fast Preset: the fast setting of the quota on the display, pressing on key RESET appears Preset and pressing
still 2 times RESET is possible to set the value directly (use keys and confirm with RESET). This
function is useful when the quote on the display has often be corrected.
Origin change (quota correction for tool change): with this function 3 different origins (0,1,2) are
programmable and passes from an origin to the other wit key RESET. Activating the function of origin change
on the display appear two small arrows and the indication of the selected origin happens with the switching
on of the origin indicators (see paragraph meaning of symbols ). After setting 4 in the first digit on the right of

//, will appear PrS0 and pressing 2 times RESET has to be set the value to be read in this position of
shaft for origin 0, confirm with RESET. It will appear PrS1 which is the value to be read for origin 1 in the
present position of shaft: set the correct value and confirm with RESET. It will appears PrS2 which is the value
to be read for origin 2 in the present position of shaft: set the correct value and confirm with RESET. It means
PrS0, PrS1, PrS2 are references for the calibration, in a certain position of the shaft, in three different origins.
Function ABS/REL:Enables the pass from absolute to relative value, pressing key zero-set temporary the
value to allow a relative shifting. On the display switches on indicator REL to indicate that the current quote is
relative to the zero-point just created. Pressing still key reappears the absolute value and on the display
switches on the indicator ABS.
Conversion mm/inch: Pressing key converts the measure from millimetre to inches and back with
indication of inch/mm on the display and a decimal number more then for millimetres. By choosing 5
decimals for millimetres the conversion in inches is not allowed.
Visualization in degrees: Pressing on key on the display appears Deg to indicate the visualization of
measure in degrees.

This parameter is added or subtracted from the current quota to correct the value showed on the display, for
example following wear or changing of tool. Setting a positive value on display appears the current quota added
to this value.
Set zero to exclude the offset function (manufacturer’s value).
The offset is not available if the function of tool-change is selected.
Adjusting of quota
After the assembling of instrument on the machine and setting of all parameters, to visualize on the display the
correct measure it is necessary to carry out the reset or preset of quota. Position the shaft in a point in which is
known exactly the correct measure that has to be visualized (ex. stroke checking) or measure the value in that
point of axis. Programme parameter //

// with value 3 in the first digit on the right and go out of the
programming. Now press RESET and it will appear Preset, press again 2 times RESET and set on the
display the correct measure to visualize, confirm with RESET and on the display appears the correct measure.
If the adjusting quota is worth to zero instead of the preset is possible use reset, setting value 1 on the first digit

accidental reset/preset of quota.
Battery change
The instrument is supplied with 2 batteries type AA of 1,5V (alkaline type) which assures a functioning of about 1
year. When the loading level goes under a certain value, the indicator of flat-battery begins to blink in occasional
way and when it keeps switched on its necessary to change the batteries within a month.
To enter into the battery-holder its necessary to take off the front-cover prising on the two hollows placed on a
side of the instrument. Take off the cover and take out the battery-holder and change the batteries paying
attention to the polarity indicated. Without batteries the instrument switches off: in this phase do not rotate the
hollow shaft to avoid loosing of correct quota. As soon as the batteries are fitted inside, the instrument
switches on with the same value on the display as at the moment of the switching off and if the shaft has not be
moved the value will be correct. In case the shaft is moved during the switching off, to re-establish the correct
measure its necessary to repeat the adjustment proceeding.
