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.

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
.

The display will show 
"
Volume = _ _ _ _ _ mL
" 
(or "Volume = _ _ _ _ _ 
Gallons

Enter the volume for the individual sample bottle by pressing the 
numerical keys.

Press

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