Display
The PR2000’s LCD has options to be either on continuously or turn
off automatically after five minutes of inactivity. This option can be
changed by first pressing the F1 key to highlight the display parameter
configuration tab. Once the tab is highlighted the option can be
changed by pressing the F1 key repeatedly or using the UP and
DOWN keys to select either “On” or “Auto”.
Backlight
Like the display, the LCD backlight also has power saving options.
The backlight can be either on, off, or set to automatically shut off after
30 seconds of inactivity. This option can be changed by first pressing
the F2 key to highlight the backlight parameter configuration tab.
Once the tab is highlighted the option can be changed by pressing
the F2 key repeatedly or using the UP and DOWN keys to select
either “On”, “Off” or “Auto”.
LED Modes
The function of the two LEDs on the upper left corner of the PR2000
can be regulated by first pressing the F3 key to highlight the LED
parameter configuration tab. Once the tab is highlighted the option
can be changed by pressing the F3 key repeatedly or using the UP
and DOWN keys to select either “Enabled” meaning the LEDs will
light to indicate device function or “Disabled” meaning the LEDs
will never light.
5.5.ii.b Display Update Mode
Selecting “MORE” by either pressing the F4 key or “OK” key while
viewing the Power Modes screen brings up the Display Update
Mode screen. On this screen, options relating to the refresh rate of
the screen are displayed. The F1 key changes the refresh rate of
the whole main screen and the F2 key changes the refresh rate of
the graphing feature. Both parameters toggle between ‘auto’ and
‘reading’. In ‘auto’ mode, the display is updated periodically according
to the time displayed by the Auto Time parameter (which can be
changed using the F3 key), whereas in ‘reading’ mode, the display
only updates after a reading is taken.
