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.
To enter into the statistics mode:
A. Press the RANGE and MODE buttons simultaneously. The number of pulses in the last statistics run and
a flashing SET annunciator will appear in the display.
B. Use the RANGE (count up) and MODE (count down) buttons to change the display to the desired
number of pulses to include in the statistics run (up to 1000).
C. Press the SELECT button to enter the pulse population to memory. The display will blank and a
flashing STATS annunciator will appear.
D. Press the MODE button to begin the run. The STATS annunciator will stop flashing. 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 for 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 until the display blanks to save the setting.
I. Press the ON/SELECT button to turn the H410 back on.
9. To Perform a Transfer Calibration:
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.
You can transfer a calibration from a calorimeter to a Vector pyroelectric detector using the Transfer
Calibration function of the H410. This function allows adjustment of the output sensitivity of your Vector
pyroelectric detector in combination with your H410 meter in order to match the average power reading from
the H410 to that of a NIST certified system. Typically a 50/50 beam splitter is used with the Vector
pyroelectric detector to be calibrated in one beam path and the NIST certified calorimeter in the other beam
path.
To enter into the transfer calibration mode:
A. Press the MODE button to start a menu cycle of J, AVG J, W, CAL and tO.
