(5) As soon as the measurement is completed, the FLASH
displays the measured value and turns the backlight and
the green LED ON for 10 seconds.
The red LED will be ON instead of the green LED if a
measurement error occurred. (See the error section for details).
When the progress bar at the right of the screen is gone, the
next measurement can be done by returning to step (3)
described above.
The value is kept on display until a new measurement is started.
(The last measurement is
stored in the FLASH’s nonvolatile
memory).
The progress bar indicates the time left of the 15 seconds rest
time of the detector. It is not possible to start another
measurement in until the countdown is over.
(6) To turn the FLASH off, press and hold the button
for 3 seconds. The Flash temporarily displays « OFF » and
turns off completely.
The FLASH turns off automatically after 5 minutes of inactivity.
2 GENERAL INFORMATION
2.1 General instructions
To ensure a long lifetime of accurate measurements, the FLASH powermeter should be maintained within
the following ambient conditions:
Storage environment temperature: 10 to 60°C, RH < 90%
Operating environment temperature: 10 to 40ºC, RH < 80%.
It is possible to store and operate your Gentec-EO FLASH powermeter beyond this range. For any
specific requirements, please contact your local Gentec-EO representative.
For the most accurate measurements, center the beam on the sensor face. The beam diameter on the
sensor should ideally be the same size as the beam diameter of the original calibration, which
corresponds to >98% encircled power centered on 50% of the sensor’s surface (this complies with the
International Electrotechnical Commission standard #1040: "Power and Energy Measuring Detector...").
Refer to the calibration certificate for the exact calibration beam diameter.
