12h, dd/mm/yyyy 24h, mm/dd/yyyy 12h, mm/dd/yyyy 24h, yyyy/mm/dd 12h, yyyy/mm/dd
24h.
Display Adjusts the brightness of the display (default: 50%).
Security Enables security for password protection. When enabled, the user settings that can

entered again.
Language Sets the display language.
Unit Preferences Unit System—Sets the system of measurement that shows on the display. Options: US
Customary or Metric. Select Units—Sets the individual measurement units that show on
the display (e.g., level, velocity, flow, temperature, surface velocity, distance, minimum
distance, maximum distance, surge level, rain, cabinet temperature, level raw
1
and surge
velocity).
Tubing Life Sets a reminder when the pump tubing is to be changed. Enter the number of pump
cycles used for the reminder (10 to 99,999).
An event is recorded to the event log when the total pump cycles are more than the pump
cycles selected. Also, an error icon shows near to the tubing life setting on the
Diagnostics>Pump screen.
After the pump tubing is changed, select Diagnostics>Pump>Reset Counters to reset the
pump cycle count to 0.
