•
To configure the sensor to« Interferometric » mode, use command $MOD2 (cf. « Mode »)
To select the « Thickness 1 », « Quality 1 » and « Intensity » data, use command
$SOD1,0,0,1,0,0,1,0 (cf. « Select Output Data »).
To adjust the display hold time for the measurement which has just been made, use directly
the keypad : Access the menu by pressing F4, adjust the display hold time by pressing keys F2
and F3 – the hold time can be adjusted to within 0.5 seconds, then exit from the menu by
pressing F1 or F4.
10.4 Functions associated with « Min/max » mode
To understand the « Min/max » mode, cf. « Going further ».
10.4.1 Set/request the lower limit for the thickness (« Min Thickness
Threshold »)
Function
Control panel
Command
Parameter/Value returned
« Min Thickness Threshold »
Set/request the minimum authorised thickness threshold
Not available
$MITn, $MIT ?
n = 5 digit integer indicating min thickness, between 0 and 32767
n = min thickness x 32767 ÷ (optical pen measurement range x
refractive index)
Example : To set the threshold at 600 µm for an optical pen whose measurement range is 3 mm
(3000 µm) and a refractive index of 1.5, n = 600 x 32767 ÷ (3000 x 1.5) = 4369
The command to send is : $MIT04369
10.4.2 Set/request the higher limit for thethickness (« Max Thickness
Threshold »)
Function
Control panel
Command
Parameter/Value returned
« Max Thickness Threshold »
Set/request the maximum authorised thickness threshold
Not available
$MATn,
$MAT ?
n = 5 digit integer indicating max thickness, between 0 and 32767
n = max thickness x 32767 ÷ (optical pen measurement range x
refractive index)
10.4.3 Related Commands
•
To configure the sensor in « Min/max » measuring mode, use command $MOD3 (cf.
