switch it on by pressing the On/Off button once for a couple of seconds. After switching on,
pressing the On/Off Button for a short period of time (less than 2 sec.) will result in toggling
the backlight or the brightness of the display (depending on the type of the display: LCD or
PLED). This means that the backlight/brightness will turn on or increase by pressing the
button once, and turn off or decrease by pressing it for the second time, turn on or increase
also for the third time, and so on. It is important to note that the LCD backlight should only be
used when it is necessary, as the power consumption is approximately tripled if the LCD
backlight is on, resulting in shorter battery lifetime. XL Meter™ can be switched off by
pressing the On/Off button for a longer period of time (more than 2 seconds). If this action is
successful you see a shutdown message on the screen before releasing the button.

Starting a measurement (data acquisition) can be invoked by the measurement button. You
can also use the red button to enter Display Mode from Calibration Mode by pressing it once.
Measurement can only be started from Display Mode. Anytime the currently displayed
measurement will be overwritten by the new measurement. You do not have to wait until all
the results are displayed, but you can anytime interrupt one display cycle and start data
acquisition. Data acquisition can be stopped by the display (green) button.
Note: Before starting measuring, the XL Meter™ Pro Gamma will ask to overwrite the actual
