selected parameter. If the selected parameter is a switch parameter (e.g. the polarity
of the laser diode) the function of the softkeys changes:
Press the right softkey to toggle the polarity.
Press to terminate the procedure.
Some parameters cannot be changed, as they are measurement values
(i.e. the laser voltage) or may not be changed during the laser switched
on. In this cases access is denied indicated by a long beep.

2.2.3 Selecting the polarity of the laser and the monitor diode

To change the polarity of the laser diode select the parameter
LDPOL =
and select the desired polarity with
To change the polarity of the monitor diode select the parameter
PDPOL =
and select the desired polarity with

2.2.4 Calibrating the monitor diode

To calibrate the monitor diode select the efficiency coefficient
C = 0.2000A/W
Press CHANGE to activate the tuning knob. Adjust the desired value and terminate
the procedure with
(Refer to chapter 2.2.2, "Changing parameters" on page 31)
The default value of η is 0.2000 A/W. It is valid without specific confirmation.
