CHAPTER 8

Advanced Use of the Analyzer – Tips and Tricks

8.1.2 Power Settings

The analyzer has an advanced power management function that takes care of supplying the

different circuits with adequate power and switches off circuits that are not in use. These power

management functions can be changed via the Power Settings screen (Fig.8.3).

Tap Power Settings, or next to Power Settings, to expand the list of power settings:

• Backlight Dim

• Standby

• Turn off Backlight (only with hardware versions 1 – 3)

• Ext. Power (only with hardware version 4 (G4))

Left: For hardware

versions 1 – 3

Right: For hardware

version 4

The backlight will be switched on as soon as you operate the analyzer, either by using the

keyboard or stylus on the touch-sensitive screen. The backlight brightness will be one of the six

levels set by tapping at the bottom of the screen. Select Minimum for minimum brightness

and (power consumption), and Maximum for maximum brightness and (power consumption).

Once you have chosen the level, select Close to save the settings.

When the analyzer has been left unused for the time specified in the Backlight Dim parameter,

the backlight level will change to the dim level (Minimum):

• For hardware versions 1 – 3, this state will hold for the time specified in the Turn off

Backlight parameter (if still left unused). If the analyzer has been left unused for the time

specified in the Backlight Dim parameter plus the Turn off Backlight time period, then the

backlight will be switched off completely (Fig.8.4). Use the keyboard or tap the screen to

switch the backlight on again

• For hardware version 4, the backlight will never be switched off completely because the

Minimum dim level already has the lowest power consumption
