Ref/Set Button

The Ref/Set button, Ref  , provides two functions:

•Press and hold to store the power level values for a set of reference cables, (Set),

•Press and release to display previously stored references, (Ref).

Test Mode: To Set a Reference

1.Refer to the sections describing connection of reference cables (see “Testing Fiber Optic Links” on page 12).

2.Set the FPM 101 to the desired measurement mode (dBm or uW) (see “dB/dBm/μW Button” in the previous section).

3.To store the currently measured level or multiple levels (in dual WAVE ID mode) as the new reference level, press and hold the Ref/Set button until HELDSET is displayed.

4.Once the new reference is set, the FPM 101 switches to insertion loss (dB) mode.

NOTE: When setting references from dual WAVE ID sources, additional time is

required for the power meter to identify and measure both wavelengths. Allow several seconds before pressing the Ref/Set button in step 3.

Test Mode: To View the Reference

1.Press the Ref/Set button to display the stored reference wavelength and power level for the currently selected wavelength or detected WAVE ID wavelengths. The reference indicator (A, below) lights, and the reference values are displayed briefly (several seconds) as follows:

Single and Dual WAVE ID mode

Continuous Wave (CW) mode — The reference wavelength and power level are displayed at B

Single WAVE ID mode — The reference wavelength and power level are displayed at B

Dual WAVE ID mode — The first reference wavelength and power level are displayed at B,and the second at C .

Splash and Auto-Off Screen

Splash (Version) Screen — During power up, the FPM 101 software version is shown on the top line, (D). The FPM 101 type and detector type are shown on the next line (E). The splash screen is replaced by the normal display after about
