Configuring Measurement Settings

To remove laser wavelengths:

1. Select Remove from the Wavelength drop down list in the Measurement

Parameters Area. The Remove Favorite Wavelength dialog box appears,
displaying the wavelengths listed in the Laser Wavelength drop down
list.

Note: Remove is only available if more than 1 wavelength is listed in the

Wavelength drop down list.

2. Select the wavelength you wish to remove. You can only remove one

wavelength at a time.

3. Click Remove to remove the selected wavelength and close the dialog

box. The removed wavelength no longer appears on the Wavelength drop
down list.

Filter Settings

The photodiode head is equipped with an optional filter that allows it to measure
up to 300mW or more without saturating the detector. The exact maximum
power is reached when the reading reaches full scale, or when the output current
from the head reaches 1.3mA, whichever comes first. You can work with or
without the filter, depending on which powers you wish to measure.

To configure the instrument to measure when the filter is inserted:

1. Select In from the Filter drop down list in the Measurement Parameters

Area.

Figure 5-5 Filter Drop Down List

To configure the instrument to measure when the filter is removed:

1. Select Out from the Filter drop down list in the Measurement Parameters

Area.

Note: Make sure to physically insert or remove the filter, according to the

filter setting selected. Failure to do so will result in erroneous
readings.
