2-A.Enter the intake tube length attached to the sampler, using the numeric

keypad. Length values from 100 to 3000 cm (3 to 99 ft) are valid. Change the measurement unit using the CHANGE UNITS key.

Note: Intake tube length affects sample volume accuracy, cut the tubing to the nearest whole foot. Avoid excessively long tubing runs. Doubling the intake tubing length can quadruple the pump tubing wear if intake rinses or sample retries are enabled. Always locate the sampler close to the sample liquid source to minimize tubing, pump, motor, and gearbox maintenance.

Step 3 - Program Lock

Note: The program lock password is configured at the factory as “9000” and cannot be changed.

Enabling the Program Lock will provide a protective “password” which will keep unauthorized personnel from tampering with the instrument keypad.

3-A.Enable or Disable Program Lock using the CHANGE CHOICE key.

Note: When program lock is enabled and a user attempts to make a change in the program, a screen will ask the operator to enter the password. The operator must enter 9000 and press ACCEPT.

3-B.Press ACCEPT to continue the basic program setup and continue with Program Delay.
