Operation
Make sure you keep a safe distant to hot sources of light. There is a risk of burns.
Never stare directly into a bright light source. This could cause damage to your eyes
• Press the button once to switch on the device.
• Press the button briey to switch off the device.
The device turns off automatically after approx. 5 minutes.
To disable automatic shut-down for the next measurement, hold down the but-
ton while the device is off and then press and hold the button. The display (2)
shows the status accordingly (”APO OFF” = automatic shut-down is deactivated).
The next time the device is turned on, the automatic shut-down will be again ena-
bled.
• When tuned on, the instrument will instantly start measuring and will show the reading in
the measured value display (7). The measured value must be multiplied by the displayed
measured value factor (8) (if shown).
• Press the button to toggle between maximum value, minimum value and instantaneous
value. The currently set display mode is shown via the MAX/MIN display (4) (no display >>
instantaneous value display).
• Press the button to “freeze” the value shown. The current measured value is perma-
nently displayed, HOLD (5) appears on the display. To return to the normal display, press
the button again.
• Hold down the button to turn the display illumination on or off.
• Press the button to change the measurement unit. The display will show which measure-
ment unit (9) is used (Lux or Fc).
• If the reading is out of the measurement range, the display (2) will show “OL”.
