Keypad Functions
[ ]
Push the power button to turn the OPM on or o. The default setting will turn the
OPM o after ve minutes of inactivity. Hold the power button for two seconds to
place the OPM into a constant on mode. Holding the power button again for two
seconds will revert to the auto o mode.
[ dB/dBm ]
Press this key to switch the measurement mode between absolute power (dBm) and
relative loss (dB). Hold the key until “HELD” is displayed.
[ Zero ]
Press the Zero key to zero the OPM with the input port protected from ambient light.
A message of “SUCC” will be displayed upon successful zeroing. If an “ERR” message
appears check that the input port was in fact covered properly and repeat the zeroing
procedure.
[ REF ]
Press this key to display the reference value stored in memory. Hold the key down
until “HELD” appears in the display. When the OPM is switched to dB mode, the LCD
displays the dierence in dB between the reference level and the current input signal.
[ ]
Press this key to select the desired wavelength. The current wavelength will be
displayed on LCD.
with an External Power Adapter 9V
DC@250mA.
The External Power LCD Indicator will illuminate when the unit is supplied from the
external power adapter.
