Verify that the Atomic Clock is properly set

 

1.     In the upper left hand corner of the Atomic Clock display you should see an antenna tower with four (4) semi-circular bands emanating from the top of the tower.  This means that the Atomic Clock is correctly set.

2.     If the Atomic Clock is not correctly set, log on to www.time.gov, after the page loads, do a refresh, then verify that the gov time and Atomic Clock time are within one (1) second.

3.     If the Atomic Clock is correct, go ahead with the time checks.

4.     If they are off by more than one second, delay the time checks until the Atomic Clock can correctly set.  If you have difficulty getting your Atomic Clock to set, try placing it in a plastic bag and setting it outside overnight.  Be sure to position the display facing away from the East to keep the sun from damaging the display.

 

Time Set Tolerances

 

1.     The PC & DAS should be within 5 seconds of the Atomic Clock.

2.     The Aethalometer, 5400, TEOM, all should be within 30 seconds of the Atomic Clock.

3.     The Partisol-Plus 2025 (FRM) should be within 2 minutes of the Atomic Clock.

 

PC & DAS Time Check/Set

 

1.     Check the current time and date in DataView to the Atomic Clock, if it is within 5 seconds and the date is correct, record the times on the “Time Set Worksheet” and go on to the devices.

2.     If the time is more that 5 seconds off, record the times on the worksheet and proceed with setting the PC time.

3.     Restart the PC, and record the times on the worksheet.

5400 Time Check/Set

 

                Note:  Do not use “Immediate Stop” to stop the 5400, instead use the “End Cycle”.  The reason being is that when the 5400 is started again, it will not go through a cleaning cycle.  It will go from         “READY” directly to “RUN” mode, with no clean cycle.  This helps to extend the useful life of the filter assemblies.  See page 5-10 of the 5400 Operating Manual for more information.  (“End Cycle” can take up to approximately 1 hour before the 5400 will stop and go into “READY” mode.)

 

1.     Check the current time and date on the 5400 to the Atomic Clock, if it is within 30 seconds and the date is correct, record the times on the “Time Set Worksheet” and go to the next device

2.     If it is more than 30 seconds off, record the times on the worksheet, and proceed with setting the time.

3.     Down all three 5400 channels.

4.     At the 5400 press “Run/Stop”, then press F2 “EndCyc”, then press any key to get to the RUN display.

5.     In the upper right hand corner you will see “RUN-C”.

6.     After some time (up to 1 hour) the display will change to “READY” - you can now change the time.

7.     Press F5 “Setup”, you will see the “Curr Time” and “Curr Date” displayed.

8.     Move the curser (flashing underline) to the time and position on the hour or minutes, whichever you are changing.

9.     Press “EDIT” and enter the desired time, then press “ENTER”.  There is approximately a 3 second delay in the 5400 writing the time, so set your time 3 seconds in advance.

10.  Allow a few seconds (10 to 30) for the 5400 to process the new time and display it.

11.  If the time is within 30 seconds of the Atomic Clock, restore the 5400 to RUN mode. Up all three 5400 Channels

12.  If not, re-set the time using the steps above.

13.  Up all three 5400 Channels

 

TEOM Time Check/Set

 

1.     Push the Time/Date button on the key pad.

2.     Check the current time and date on the TEOM to the Atomic Clock, if it is within 30 seconds and the date is correct, record the times on the “Time Set Worksheet” and go to the next device.

3.     If it is more than 30 seconds off, record the times on the worksheet, and proceed with setting the time.

4.     Down the TEOM channel.

5.     At the TEOM press “TIME DATE”, the current time and date will display.

Partisol-Plus 2025 (FRM) Time Check/Set

 

     Checking the FRM Time

 

1.     At the FRM, press F5 “Setup”, after the display changes, press F5 “System”

2.     The System Setup screen will display.

3.     The “Curr Time” and Curr Date” display on the bottom left.

4.     Check the current time and date to the Atomic Clock, if it is within 2 minutes and the date is correct, record the times on the “Time Set Worksheet” and go to the next device

5.     If it is more than 2 minutes off, record the times on the worksheet, and proceed with setting the time.

 

     Setting the FRM Time

It is necessary to stop the FRM sampling cycle in order to change the time.  To restore the FRM back to sampling the current filter, it will be necessary to go to Service Mode and eject the current filter and re-feed it into the sample position.  This requires filter handling - so ware plastic gloves.

 

1.     Press “RUN/STOP”, then press F2 “STOP”.  The FRM is now in stop mode.

2.     Press F5 “Setup”, when the screen changes press F5 “System”.

3.     Move the curser (flashing underline) down to the “Curr Time” and position it over the minutes.

4.     Press “EDIT”, the curser will change to a flashing black block, enter in the correct minutes, press “ENTER”.

5.     Wait 10 to 20 seconds for the “Curr Time” to display the correct time, if correct continue, if not re-set the time using the steps above.

6.     You now have to set up the FRM to return to sampling today’s filter.

7.     Press “ESC” (may be more than one press) to get back to the Main Screen.

8.     Press F3 (FiltSet), move the curser to the day in the date, press “EDIT” and enter today’s date, press “ENTER”.  The date should be today’s date. Press any key to accept.

9.     When the FRM starts up again, it will do a filter exchange, which means that today’s filter will be ejected and tomorrow’s filter will be in position to sample - so we need to cycle today’s filter out and reinsert it in the supply magazine, so that it will end up in the sample position when the FRM is started.

10.  To do this the FRM must be in Service Mode.

11.  Press “MENU”, in the main menu scroll down to “Service Mode” and press “ENTER”, then press F4 “Yes”.

12.  In the Service Menu scroll to “Manual Motion Tests”, press F4 “FiltChg”, then press F4 “Start”.

13.  The FRM will perform a filter exchange and advance tomorrows filter to the sample position and eject today’s filter into the receiver magazine.

14.  You will now have to move the filters from one magazine to the other, so put on the plastic gloves.

15.  Move the top filter (today’s filter) in the receiver magazine to the top position of the supply magazine.  Make sure both magazines are properly reinstalled.

16.  Press “MENU”, in the Service Menu scroll down to “Exit Service Mode”, press “ENTER”

17.  Now start the FRM.  Press “RUN/STOP”.

18.  The FRM will exchange filters and start sampling.  Today’s filter will be in the sample position and tomorrow’s filter will be in the receiver magazine.

19.  Move the top filter (tomorrow’s filter) in the receiver magazine to the top position of the supply magazine.  Make sure both magazines are properly reinstalled.

20.  The FRM is back to normal operating status.  With the correct time!
