·

Units

·

Delta Mode: This allows zeroing to an absolute given value.

·

CW or Pulsed

·

Analog Filter (or bandwidth)

·

Trigger

Beam

Please adjust the following settings for the excitation source prior to a measurement:

·

Beam Shape

·

Beam Profile

·

Beam Size/Beam Area

Entering the actual beam diameter, shape and profile is used to calculate the beam area. This enables the
calculation and display of measurement values in irradiance or fluence.

Sensor Info

: Information about the sensor, imported from the EEPROM of the senosr, is displayed. 

Analog  Output: 

Configured the output port for signal analysis via an external device.
