1-C. Enter the bottle volume using the numeric keypad and select gallons or
milliliters using the CHANGE UNITS key.
1-D. Press ACCEPT and continue to Intake Tubing.
Step 2 - Intake Tubing
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.
2-B. Press ACCEPT to move to the Intake Tube Type menu.
2-C. Select the type of intake tube ( 3 / 8 in. Vinyl, ¼ in. Vinyl, 3 / 8 in. Teflon ® )
using the CHANGE UNITS key.
2-D. Press ACCEPT to select the intake tube type and continue with Program
Lock.
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.
