    • Note: When setting the time and date, the * key causes the display to back up to the previously flashing character.
      • 1. Check the real-time clock and date settings by pressing TIME/READ. The display will show the time and date for several seconds: 10:35 AM 24OCT00
      • 2. If the time or date are not correct, press TIME/SET. The time and date will appear on the display, with the hour flashing.
      • 3. Press the appropriate numerical key(s) for the correct hour. When the correct hour flashes on the display, press YES. This will cause the minutes to flash on the display.
      • 4. Using the same procedure, select the correct minutes and press YES. The am/pm indicator will flash.
      • 5. If the desired indicator is flashing on the display, press YES. If the desired indicator is not flashing, press NO. This will cause the other indicator to flash.
      • 6. Press YES. The month will begin to flash. Select the correct day, month and year using the same procedure as you used to set the time.
      • 7. After the correct year has been entered, the display will read "Synchronize Time-enter at Time". Pressing YES will start the clock. The display will read "Clock is Now Set".
  • 4.4 Bottle Setup Mode
    • 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.
  • 4.5 Explanations of Program Messages
  • 4.6 Data Logging
    • 1. To access information, the sampler must be in the "Program Halted" or "Program Complete" standby state.
    • 2. Press TIME/READ for two seconds. The display will read "Samples Taken".
    • 3. To display the time/date for each sample, press YES. To advance to the next sample time/date, press YES again-and so forth, until all are given.
    • 4. To exit this routine, press NO. The time and date of any missed samples are displayed after collected samples.
  • 4.7 Manual Mode
    • 4.7.1 Manually Operating the Sample Pump
      • 1. To manually operate the pump, place the sampler in standby state. The sampler is in standby state when the display reads "Ready to Start", "Program Halted", or "Program Complete".
      • 2. To operate the pump, press either the PUMP or PURGE key. This will cause "Manual Mode - Pump/Purge/Clear" to appear on the di...
      • 3. To run the pump continuously in either direction without having to hold down the PUMP or PURGE keys, press the * key. This will cause "Lock-Pump/Purge" to appear on the display. Then press either PUMP or PURGE.
      • 4. To stop the pump, press STOP PUMP or turn the sampler off with the OFF key. Pressing STOP PUMP returns the display to "Pump/Purge/Clear".
      • 5. To exit the manual mode, press CLEAR ENTRY. This returns the sampler to the standby state.
