Each X and Y coordinate is a signed 16-bit value. Also, the value "0x7FFF"
indicates that measurement is not possible.
After you acquire 126 data points worth of data, specify the address 252
words (126 data points x 2 words) worth of data after the current address,
and then use the same procedure to acquire the next data. Repeat this oper-
ation until you have acquired all the data.
To draw the profile, plot the acquired X and Y coordinates in order.
Tips:
•
A thinning value is specified to speed up data communication by thinning the
profile data points.
For example, the commands shown below would perform thinning of at each
data point (which would reduce the data points acquired by half).

In this case, acquired coordinates are: 0, 2, 4, 6, etc.
A thinning value up to 2F (1/15 thinning) can be input.
