MAINTENANCE & TROUBLE SHOOTING
128
Sustained operation of the System 5000
™
is generally maintenance-free. There are no
desiccants or serviceable parts to maintain.
The touchscreen interface, however, can
be calibrated for finer precision when
necessary.
Maintenance
To re-calibrate the touchscreen, follow the onscreen prompts by pressing the center of the
crosshair displayed on the screen. A finer precision can be achieved by pressing each crosshair
for a few seconds, rather than a quick press. This allows more samples to be taken and a more
accurate averaging to take place.
Touchscreen Calibration
The touchscreen calibration menu can
be accessed by holding in the View
Status button while applying power to
the System 5000
™
. Continue to hold the
View Status button until the first
System 5000
™
splash screen appears.
Within a few seconds, a simple
touchscreen calibration menu will
appear.
When completed, the newly calibrated
settings can be tested.
If finer calibration settings are still
required, the calibration can be retried
by pressing the Retry Calibration button.
If the new settings are acceptable, press
the Exit and Restart button to reboot
the System 5000
™
with the new
calibration settings.
