•
Manually changing the electrical gain range.
•
Setting the GPIB address.
•
Setting the power during the User Calibration.
The GPIB LOCAL button is used to take the 6810B out of
REMOTE operation and to change the GPIB address. While in
REMOTE, press LOCAL to return the device to local, front panel
control. While in LOCAL, press LOCAL to display the GPIB
address. While the GPIB address is displayed, use the RANGE UP
and DOWN arrow buttons to change the address.
The POWER AUTO button is used to toggle the instrument
between automatic and manual gain ranging control. If the
POWER AUTO indicator is lit, the unit is in autoranging mode
where the device selects the gain range automatically. If the LED
above the POWER AUTO button is not lit, the POWER UP and
DOWN arrow buttons must be used to manually select one of eight
electrical gain ranges. The magnitude of the change is evident by
viewing the bargraph display.
The Power UP and DOWN arrow buttons are multifunctional.
The functions are listed below.
Press the WAVELENGTH AUTO button to toggle the unit between
automatic wavelength measurements and manual wavelength
settings. If the LED above the WAVELENGTH AUTO button is lit,
the unit is measuring the wavelength of the source and
automatically setting the correct detector responsivity for power
measurements. If the LED above the WAVELENGTH AUTO button
is not lit, the unit is in manual wavelength mode where the
WAVELENGTH LEFT, RIGHT, UP and DOWN arrow buttons are
used to manually set the wavelength of the source being
measured. This feature is disabled with power only measurement
heads.
