steps in order.

Note: You can exit the wizard at anytime by pressing Exit Certification.

To use the Loss Certification Wizard:

1. Press , and then select Loss Certification Wizard.

2. Using the up/down arrows, select

Fiber type and press .

3. In the list, select the fiber type and

press .

4. Select the threshold type you

intend to use (see Setting Pass/Fail

Thresholds on page 16).

5. Select a transmission standard.

6. Press Next.

7. Select Length measurement

method and press .

8. Select one of the following

options:

³ Manual entry: when you

know the cable length.

³ Sheath marking: when you

want to use the provided

marks on the cable sheath to

evaluate the actual length.

9. Press and press Next.

Using the Loss Certification Wizard

4 Measuring Power or Loss

Nulling the Offsets

Temperature and humidity variations affect the performance of electronic

circuits and optical detectors. Nulling the offsets eliminates these effects.

Your unit has been designed not to require offset nulling under normal

operation, but you should perform it whenever environmental conditions

change significantly or when measuring very low power values.

By default, when the unit detects a significant change in temperature or

humidity, it displays a message requesting you to perform an offset nulling.

This feature can be deactivated from the Power Meter Configuration

pane, refer to Deactivating the Offset Nulling Message on page 15.

To perform an offset nulling:

1. Press , select Power Meter,

and then Instrument View.

2. Using the arrows next to the

function keys (F1/F2/F3), display

the Offset Nulling tab.

3. Press the function key

corresponding to Offset Nulling.

4. Place the protective cap on your

power meter detector.

5. Press or Start.

IMPORTANT

Light must not reach the detector when nulling offsets; always use a

protective cap.

Defining a List of Favorite Wavelengths

You must put the wavelengths you want to use on a list of favorite

wavelengths. Specifications are guaranteed for calibrated wavelengths

only. For other wavelengths, the unit will determine values based on the

calibrated wavelengths (3-point interpolation).

To add a wavelength to the power meter list:

1. Press , select Power Meter,

and then Configuration.

2. From the Power Meter tab, select

Item, and press .

All the wavelengths available in

the power meter are followed by

PM=Yes.

3. If you are satisfied with the list,

press .

OR

If you want to add a wavelength,

close the list, select New

Wavelength, and enter a value.

The new value appears in the

Item list followed by PM=Yes.
