Days/cycle
For regular sequence set this parameter to 1. To set a timed sequence of a
different number of days, see below.
Days/cycle: It is possible to program a timer sequence that repeats after a
fixed number of days. An example is to program a 6-day sequence for EPA
sampling by setting the Days/Cycle parameter to 6. In this way, it is possible
to program the HiVol 3000 to collect a sample on Friday, then the following
Thursday, then the following Wednesday, etc. which commences at the
programmed Start Date and will continue until the End Date is reached. All
conditions must be met for the sampling to commence, so make sure that the
Start Date, End Date, Daily and Weekly parameters have the parameters set
correctly. It is possible to program a 6 day sequence, which never samples on
Sundays for example, by setting the Sunday parameter to NO in the Weekly
Menu.
Example. To program a 6 day sequence, with the first run day as 21/06/2005
for a 24 hour sample.period.starting at 0000hrs
Start date: 21/06/2005
Start time: 00:00
End date: 1/1/2100 (i.e. some point in the distant future)
Daily: set On Time 1 to 00:00
Off Time 1 to 24:00
Weekly: all days to yes
Days/cycle: 6
Important Note:
For an n-Days/Cycle sequence the Start Date is a
sampling day. The HiVol determines subsequent run
days based on the Start Date.
