Averaging time
Measurement response time
The measurement response time can be calculated with the following formula.
• Distance mode: Measurement response time = Average measurement time + Update cycle (T5) +
Internal processing time (T1)
• Profile mode: Measurement response time = Averaging response time + Average measurement time
+ Update cycle (T5) + Internal processing time (T1)
“Timing Details” (page 7-13) for average measurement time, update cycle (T5), and internal processing
time (T1).
Power ON reset time
This is a period of time taken to start measurement after turning on the power.
• Power ON reset time = approx. 10 sec.
The update cycle of the screen display of the microscope image and measured value differs depending on the
scan settings.
