Setting the Sampling Rate of Measurement Value
This section describes how to set the measurement sampling sycle. If you want the sampling
to be performed more quickly, modify it to perform faster or when the received light is extremely
dim, modify it to perform more slowly.
■ Setting procedure of the sampling rate
1
Hold down the key, and select " oPt on " with the key.
Set the common settings.
2
Press the key, and select function " A " by the key.
Set the sampling cycle.
3
Press the key, and select " A-4 " with the key.
The sampling rate is set as "500" µs in this example.
4
Press the key to register the setting. Press the
key to return to the measurement state.
• The sampling rate will be doubled when two heads are connected and the sampling
rate is set as 20 µs.
• Set the sampling rate to other than 20 µs (other than 20 µs and 50 µs when transparent
object 2 is selected in the LK-G85/G80/G87/G82/G155/G150/G157/G152/G405/G400/
G407/G402, and other than 20 µs, 50 µs and 100 µs when transparent object 2 is
selected in the LK-G505/G500/G507/G502) when one of the items from transparent
object, transparent object 2, and multi-reflective object is selected in the
measurement mode of the head (
page 3-7).
• The sampling rate will be up to four times slower when the transparent object 2 is
selected.
• Do not use the measurement value display or received light waveform display of the
setup support software "LK-Navigator" when setting the sampling rate to 20 µs.
