4.4 Bottle Setup Mode

When programming the sampler for the first time, you must first access the

bottle setup mode which contains set-up information such as the units for

bottle volume (milliliters and gallons) and the bottle volume.

To access the Bottle Setup Mode, the sampler must be in standby state, the

program cannot be in progress or "running". The sampler is in standby state

when the display indicated any one of the following: "Ready to Start",

"Program Complete", or "Program Halted". If the display reads "Program

Running", press the

CHANGE/HALT key. This will halt the program, thus

placing the sensor in the “Program Halted” standby state.

1. With the sampler in standby state, press the * key. The display will read

“Enter units for bottle volume, milliliters?”.

2. Press NO to cause other volume units to appear. When the desired units

appear on the display, press

YES.

3. The display will show "Volume = _ _ _ _ _ mL" (or "Volume = _ _ _ _ _

Gallons

"), whichever was chosen in the previous step.

4. Enter the volume for the individual sample bottle by pressing the

numerical keys.

5. Press YES to accept the volume.

This completes the bottle setup entries and the sampler is ready to program.
