FIBER METER

• Switching the Fiber Meter handsets from Remote

to Main operation.

The Fiber Meter compensates for changes in ambient

temperature. For optimum performance, allow the test

system to adjust to the ambient temperature of the test

area before setting the Autotest reference.

You'll also need to re-establish the reference when there

has been a significant change in temperature since the

reference was last established. If the Fiber Meter is used

over long intervals of time, you should re-establish the

reference every couple of hours to allow for changes in

ambient temperature.

Use test jumpers that are of the same type of fiber as the

cable you will test (either 50/125 µm or 62.5/125 µm).

You can use either of the following two reference setting

methods:

• Method B per TIA/EIA-526-14A (OFSTP-14A);

this is described in Section 5.2.1.

• Method A per TIA/EIA-526-14A (OFSTP-14A);

this is described in Section 5.2.2.
