B. To Measure Average Energy (J AVG):
Note: The maximum repetition rate for average energy is 300HZ.
The average energy mode displays an average of a selectable number of pulses from 2 to 9999.
i. Press the MODE button to start the menu cycle of J, AVG J, W, CAL and tO.
ii. Press the ON/SELECT button when the AVG J annunciators appear on the display. The number of
pulses to be averaged will now appear in the display.
iii. To change the number of pulses to be averaged, press the RANGE (count up) and/or MODE (count
down) buttons until the desired number of pulses to be averaged appears in the display.
iv. Press the ON/SELECT button to select the pulse population. The average energy of the number of
pulses you selected will be displayed after the number of pulses entered in step iii is received by the
pyroelectric detector. This is not a running average, but is the average for the pulse population
selected in step iii. Nothing is displayed until the full pulse population is delivered. This average is
displayed until another full population of pulses is delivered at which time the display is updated
with the average for that population of pulses.
v. Press and hold the OFF/CANCEL until the display blanks to save the setting.
vi. Press the ON/SELECT button to turn the H410 back on.
C. To Measure Average Power (W):
Note: The maximum repetition rate for average power is 300HZ. The minimum repetition rate
for average power is 10Hz.
Note: The average power mode displays the average power (watts) of repetitively pulsed lasers.
Pyroelectric detectors will not work with continuous wave lasers.
The average power mode displays the average power of repetitively pulsed lasers.
i. Press the MODE button to start the menu cycle of J, AVG J, W, CAL and tO.
ii. Press the ON/SELECT button when the W annunciator appears on the display.
iii. The average power will be displayed.
iv. Press and hold the OFF/CANCEL until the display blanks to save the setting.
v. Press the ON/SELECT button to turn the H410 back on.
8. To Measure a Statistical Run of Energy Pulses:
Note: Do not use AUTO range when making a statistical run.
Note: Do not go from the Average Power Mode to Stats since the range will be too high. Select
the range manually.
Note: Each time a new stats run begins, data from the previous run is lost.
Note: To exit the statistical mode at any time, press the OFF/CANCEL button.
Note: Statistics mode can collect data at repetition rates of up to 300 Hz depending on the
detector model.
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 statistics mode will collect data on a pulse population of up to 1000 pulses. At your prompting, the
indicator will display the number of pulses delivered, average energy, minimum energy, maximum energy,
standard deviation, and coefficient of variation. When the statistics mode is selected, the energy mode is
automatically activated regardless of the mode previously selected. Select the appropriate range for the pulse
