7. To Select a Mode:

Available pyroelectric modes are: Energy (J), Avg. Energy (J AVG), Average Power (W AVG), and Volts (V).

A. To Measure Energy (J):

Note: The update rate of the display is 20Hz.

Press the MODE button (repeatedly, if necessary) until the “J” annunciator appears in the display.

ii.

Press the SELECT button (or wait 3 seconds) and the joules mode will automatically be activated.

iii.

The energy level of each laser pulse will be displayed on the LCD.

B. To Measure Average Energy (J AVG):

Note: The maximum repetition rate for average energy is 300HZ.

Press the MODE button (repeatedly, if necessary) until the “J AVG” annunciator appears in the
display.

ii.

Press the SELECT button (or wait 3 seconds) and the average joules mode will be automatically
activated. The number of pulses to be averaged will now appear in the display. You may select the
number of pulses to average from 2 to 9999.

iii.

To change the number of pulses to be averaged, press the RANGE (count up) and/or MODE (count
down) buttons. When the desired number of pulses to be averaged appears in the display, press the
SELECT button.

iv.

The average energy of the number of pulses you selected will be displayed after the number of
pulses entered in step ii is received by the pyroelectric detector. This is not a running average, but is
the average for the pulse population selected in step ii. 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.

C. To Measure Average Power (W AVG):

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.

Press the MODE button repeatedly until the “W AVG” annunciator appears.

ii.

Press the SELECT button (or wait 3 seconds) and the S310 will automatically enter into its
operational state in the average power mode.

iii.

The average power will be displayed.

D. To Measure Volts (V):

Note: The maximum repetition rate for volts is 300HZ.

Press the MODE button repeatedly until the “V” annunciator appears.

ii.

Press the SELECT button (or simply wait 3 seconds) and the S310 will automatically enter into its
operational state in the volts mode.

iii.

The volts per pulse will be displayed.
