10. 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.
11. 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
power meter 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 energy level to be measured. It is very important to select the most appropriate range. If you
have selected a manual range and the laser pulse(s) has overflowed the maximum energy of the range, OF
will be displayed when the data is recalled. You should then select a higher range.
