OPM4 Models
REF. # DESCRIPTION
1
Battery status indicator
- displays estimated battery life remaining. The 3 bars indicate
the charge level. When the battery is low, the battery indicator will flash.
2
REF indicator
- appears to indicate previously stored reference value(s).
On the Ref key press, the reference indicator REF
2
and reference value(s) for the currently
selected wavelength or detected WAVE ID wavelength(s) will be displayed briefly (for about 2-3
seconds).
CW mode
- the reference value will be displayed in the field
5
.
Single WAVE mode
- The reference value will be displayed in the field
5
.
Dual WAVE mode -
The reference values will be displayed in the fields
5
and
7
.
Tri WAVE mode -
The reference value will be displayed in the field
5
and
7
on the first
page and in the field
5
on the second page (replaces first page automatically in ~ 2 seconds).
3
WAVE ID indicator
- Will be displayed if the OPM4 is receiving a wavelength ID’d light.
4
CW mode
- This field displays the currently enabled wavelength.
Single WAVE mode
- This field displays the detected WAVE ID wavelength.
Dual WAVE mode
- This field displays the first detected WAVE ID wavelength.
Tri WAVE mode
- This field displays the first WAVE ID wavelength and the third WAVE ID
wavelength that is shown on a second page (replaces first page automatically in ~ 2 seconds).
5
This field displays measured power dBm or µW or insertion loss dB at the wavelength displayed
in the field
4
.
If power or loss is too high or low for the OPM4 to measure, this field will display HI or LO.
6
CW mode
- This field displays modulation frequency if detected.
Dual WAVE mode
- This field displays the second wavelength.
7
Dual WAVE mode
- This field displays measured power dBm or µW or insertion loss dB at the
wavelength displayed in the field
6
.
If power or loss is too high or low for the OPM4 to measure, this field will show HI or LO.
