b. Use the default values or enter new values in the following fields:
• Air Temperature
•Air Pressure
• Relative Humidity
c. In the Material Compensation box, select Manual.
d. Use the default values or enter new values in the following fields:
• Average Material Temp
• Expansion Coefficient
The system saves the values last entered on this screen. It uses them in
all linear measurement calculations unless you enter new values or select
Auto.
For instructions on completing the other fields on the screen, use the
online help.
9 When you have completed the screen, select OK.
You are returned to the Set Up Laser: LINEAR screen.
You are now ready to mount and align the optics on the target machine.
Go directly to “Mounting and Aligning the Optics on the Target Machine.”
Placing and Using the Sensors
Environmental conditions in your work environment affect the accuracy of
your linear measurement. These conditions include air temperature, air
pressure, relative humidity, and material temperature. The Agilent 5530
uses optional air sensors and material temperature sensors to measure
these conditions and adjust the measurements accordingly. If multiple
sensors of the same type are used, the software averages their results.
Figure 2-4 shows typical air and material temperature sensors placement
in a system.
