Push the UP and DOWN arrows to change the value. Push the LEFT and RIGHT arrows to move
the cursor.
Option Description
Date and Time Sets the time and date. Selects the format for the date and time. Options: dd/mm/yyyy
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
change the data in the logs or the sampling program cannot be changed until the
password is entered.
When the display switches off or the controller power is set to off, the password must be
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.
Clear Data Erases the sample history and/or the log(s) selected. Options: Sample History, Data Log,
Event Log, Alarm Log and Diagnostics Log.
Restore Factory
Defaults Sets all the controller settings back to the factory defaults. Erases the logs and sample
history. The display shows the startup screen for approximately 2 minutes while the
defaults are restored back to the factory defaults.

Liquid Detect Enables or disables the liquid detector. Calibrates the liquid detector
2
.
Enabled (default)—Select enabled to use the liquid detector to sense liquid in the tube,
which is an important part of volume accuracy and repeatability. Make sure to select
enabled in applications where liquid level changes occur.
Disabled —Select disabled
when the sample is collected from a pressurized line or when the sampler is below the
sample source, which can result in trapped water.
1
Level raw is the value of the level measurement before the algorithm that adjusts for the
Bernoulli effect is applied.
2
Calibrate the liquid detector only with the guidance of technical support.
