Quickstart - sylvac D70A Manuel D'utilisation

4. Quickstart

1 – Connect the air input to the air preparation unit ref 804.2203. The air pressure should be at 2
BAR (0.2Mpa) and never exceed 4 BAR (0.4MPA). It is advised to lock the pressure adjustment in
order not to let someone change the pressure value after having calibrated the display. Air gaging
corresponds to a pressure variation measurement, if the air input change, the dimensional result
on the display will change accordingly.
2 – Connect your air gage on the output « OUTPUT – AIR GAGE »
3 – Power the D70A either with the mini USB or with the 24VDC terminal.
4 – Turn on the D70A by pressing the ON-OFF switch.
5- Calibration of the device :
Note : To be done the first time, and can be done or verified again periodically (wear of the master
or the gage)
The D70A requires 2 masters for the calibration. The MIN and MAX masters should respectively
correspond to the lower and upper tolerance limits of the measured part.
A – From the « SETUP » icon, write the master values according to your calibration certificate. The
display need 2 masters MIN and MAX to be used.
B – Place your MIN master in measuring position and press on the corresponding « P » button.
The button becomes green for a couple of seconds.
C – Repeat the step B for the MAX master.
D – You can check by placing again the MIN master. The value on the « position » field must be
at 0.0000, then by placing the MAX master, the « position » field must indicate the dimensional
difference between the 2 masters.
6 – Configuration of the part to be measured. (From the Icon « definition »)
A – Use the scroll bar to reach the 2nd screen.
B – Write the value of MIN and MAX tolerances (that should correspond to your MIN and MAX
masters). The tolerance must be written relative from the nominal value. For example if your part
has a nominal diameter of 10mm +/-0.005, you must write in the Upper tolerance 0.005 and lower
tolerance -0.005, and in the nominal field: 10. It is then advised to use the min master in the case
of external diameter measurement, and to use the MAX master in the case of internal diameter
measurement. So you need to fill the « Master » field with the adapted value.
