C. Press the ON/SELECT button to enter the pulse population to memory. The display will blank and the

STATS annunciator will flash.

D. Press the MODE button to begin the run. The STATS annunciator will stop flashing and the indicator

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 indicator 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.

I. Press the ON/SELECT button to turn the H410 back on.

9. 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.
• An attenuation factor of 4 would display the value of the source.

To enter into the attenuation factor mode:

A. Press the MODE button to start a menu cycle of J, W, CAL and tO and cd.

B. Press the ON/SELECT button when the CAL annunciator appears. A second menu cycle of tCon, SPd

and Attn will start.


C. Press the ON/SELECT button when the Attn annunciator appears. The current attenuation factor will be

displayed and SET will flash.

D. Press the RANGE (count up) and MODE (count down) buttons to change the attenuation factor to the

desired value. Values of 0.01 to 99.99 may be selected.
