• Manually changing the electrical gain range.
• Setting the GPIB address.
• Setting the power during the User Calibration.

Wavelength Automatic / Manual Control

If the LED above the WAVELENGTH AUTO button is not illuminated the
instrument 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.

Setting the Wavelength

• Use the LEFT and RIGHT arrow buttons to select the digit on the WAVELENGTH display
• Use the WAVELENGTH UP and DOWN arrow buttons to increment or decrement the
• Commonly used wavelengths may be stored or retrieved by using the WAVELENGTH

Front Panel Controls
The Power UP and DOWN arrow buttons are multifunctional. The
functions are listed below.
Press the WAVELENGTH AUTO button to toggle the instrument
between automatic wavelength measurements and manual
wavelength settings. If the LED above the WAVELENGTH AUTO
button is illuminated the instrument is measuring the wavelength of
the source and automatically setting the correct detector
responsivity for power measurements. The WAVELENGTH AUTO
mode is locked out on power only measurement heads.
In manual wavelength mode, it is important to program the
6810B with the wavelength of the laser being measured so
the correct calibration factors are used to compute power.
Use the following procedure to set the wavelength via the
front panel.
