the power or energy reading exceeds the upper limit of the range. See the Group Settings section for
details.
7. To Select a Measurement Mode
The modes available for the calorimeters are: Energy (J) and Power (W).
8. To Measure Energy (J)
Note: Calorimeters can only measure single shot energy pulses with the time between pulses dependent
on the calorimeter delay setting from section 5J. With the calorimeter delay entered, the H410 will display
the "trig" annunciator and the single pulse energy after the first pulse is delivered. The "trig" annunciator
will then disappear after the calorimeter delay time has elapsed prompting you to fire another pulse. Do
not fire another pulse until the “trig” annunciator disappears. If you do, the H410 resets the time delay and
ignores the sequential pulse altogether.
Note: Make sure the calorimeter delay, set in section 5J, is shorter that the time out set in section 10. If
not the H410 will go into sleep mode before the pulse energy is displayed.
i. Press the MODE button. A menu cycle of J, W, CAL, tO and cd will begin.
ii. Press the ON/SELECT button when the J annunciator appears and the joules mode will be
activated.
iii. The energy level of each laser pulse will be displayed.
9. To Measure Power (W)
Note: The speed-up circuit is not active in AUTO range.
The average power mode displays the average power (watts) of repetitively pulsed lasers or continuous
wave lasers.
i. Press the MODE button. A menu cycle of J, W, CAL, tO and cd will begin.
ii. Press the ON/SELECT button when the W annunciator appears and the watts mode will be
activated.
iii. Press the CANCEL button to zero the display.
iv. The power will be displayed.
