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.
