3.2 Operation and Settings
The ERM100 is controlled by five buttons on the front. A LC display on the front panel shows all
measurement data in various display configurations. All necessary settings can be easily done
using the control buttons and will be shown on the display.
There are two display modes. In 'Main Display Mode' the actual measurement data is dis-
played. In 'Menu Mode' addition measurement parameters can be modified and system inform-
ation will be shown. The button 'MENU' is used to toggle between this two modes.
3.2.1 Main Displays
There are three different measurement screens. The ' SET ' button is used to toggle between
these displays:
The ER display presents the current ER measurement value in dB as well as the current mis-
alignment angle in degree:
The ERmin display shows the minimum ER in dB since the last ERmin-Monitor reset and the
corresponding misalignment angle in degree:
Pressing the button 'CLR' (Clear) while in 'Main Display Mode' resets the minimum ER mon-
itor and the minimum ER value measured from that moment is displayed in the ERmin display.
The last screen is the
power display . It shows the power in dBm and the wavelength in nm:
Setting the Wavelength
Setting the wavelength is necessary to determine the correct power. This set value will impact
only the power value but no other measurement values.

Press the ' SET ' button until the power and wavelength menu is displayed.
·
Press ' UP ' and ' DOWN ' buttons once: The " Set Wavelength " display comes up for about 2
seconds.
