• Saver Level - Only available when the Dim Saver function is set to Use Saver Bright-
ness. Select this to use the instant dimming slider which lowers the screen brightness.
Default screen brightness is 80%. Adjustable between 10% and 100% of full brightness.
This works on a square law rule that means if you reduce the saver level by 25% you
will double the backlight life. If you reduce the saver level by 50% you will quadruple the
backlight life. Normal backlight MTBF at 100% brightness is:
• • QX 55,000 hours (86,500 at 80% brightness)
• • SX 43,000 hours for the (67,000 at 80% brightness)
• • QXe 40,000 hours (62,500 at 80% brightness)
When the configuration is complete select the Finish button to Commit, Discard or Commit
Later. Select the Back button to return to the previous menu.
Note . Once you enable the screen saver it will not turn off the backlight if at the time of the
Timeout there is a pen in alarm. The screen will stay on until the alarm is gone and the Time-
out is passed. Once the Saver is active and screen is Dark (backlight is off), it will turn back
on if a pen goes into alarm.
Exit Screen Saver
If the screen saver is active on the recorder, any of the following will deactivate the screen
saver:
• User touches the recorder screen.
• Any USB device is plugged in or unplugged.
• On alarm - An alarm is triggered, the unit will not return to screen saver till the alarm
state is inactive and another screen saver time-out period has expired.
Charts
(Main Menu > Configure > Setup > Edit Setup> Screen > Charts)
A Chart speed is the time it takes the data to travel from one side of the screen to the other.
The recorder has up to 10 different chart speeds. There are 3 categories that can be set;
Slow, Medium and Fast (default). Set up each category to display the desired chart speed.
Limits are in place so that each speed cannot overlap. Eg. a Medium speed cannot be set
faster than the Fast speed.
