D. Press the MODE button to begin the run. The STATS annunciator will stop flashing and the power
meter will automatically stop once the data has been collected.
E. Press the ON/SELECT button to recall the data to the display one item at a time. Each time the
ON/SELECT button is pressed the following statistical calculations will be sequentially displayed:
Number of pulses collected
Average energy (AVG)
Minimum energy (MIN)
Maximum energy (MAX)
Standard deviation (SIGMA)
Coefficient of variation (CV%)
F. Press the ON/SELECT button one more time to return to step D to begin a new stats run. The
flashing STATS annunciator indicates that the H410 is ready for a new run. Each time a new run
begins the data from the previous run is lost.
G. Press the OFF/CANCEL button to return the power meter to the mode of operation in effect prior
to statistics mode.
H. Press and hold the OFF/CANCEL button until the display blanks to save the settings.
H. Press the ON/SELECT button to turn the H410 back on.
11. Attenuation Factors
Note: You must enter an attenuation factor of 1.0 when not using an attenuator.
Note: You must save all settings by pressing and holding the OFF/CANCEL button until the display
blanks. If the H410 is turned off, by using the ON/OFF slide switch, before settings are saved, they will
be lost.
The attenuation factors of optics can be entered into the H410 so the displayed value will automatically
compensate for the amount of attenuation. For example, assume a beam splitter is being used that
transmits 75% and reflects 25% of the beam. If the H410 is set up to measure the reflected beam the
attenuation could be set up as follows:
• An attenuation factor of 1 would display the value of the reflected beam.
• An attenuation factor of 3 would display the value of the transmitted beam.
