6: In-day Times

The Phoenix II has a special function called In-Day Times. In-Day Times are time periods in the day that you wish to

Start and Stop collecting data. This is similar to the Daily files function, except you can Start and Stop collection at

several different times during a 24 hour period. The basic purpose of this function is to handle very large data collection

requirements where you only have enough memory in the counter to store part of a day.

A day can have up to five (including zero) Start/Stop periods. You do not need to collect data during the entire day nor

do you need to make sure that these periods of collection follow each other exactly. For example, you could collect data

from 8am to noon, and then from 4pm to 8pm. The rest of the day no data would be collected and the counter is

considered to be in the Preset Active Mode (see Section 4.3.6).

In-Day times will work with any type of data collection (Raw, Binned, Count, or Sensor). If collecting Binned or Count

Data and you do not specify an In-Day Stop Time at the end of an interval, then you will lose the data of the current

interval unless the next In-Day Start time is the same as the Current In-Day Stop time.

For example, suppose you are collecting Binned data in 1 hour intervals and you have specified an In-Day period from

10:00 to 11:30 and a second In-Day Period from 11:30 to 14:00. The counter will close the current file at 11:30 and then

open a new file immediately because the next In-Day period starts at 11:30. The current Binned data interval (which is

from 11:00 to 11:59) will be preserved and will be written to a second file as its first interval even though the file was

opened at 11:30. This is identical to retrieving the open file data when it is in the middle of an interval.

On the other hand, had you specified the second period to start at 12:00, all of the data from the 11:00 to 11:59 interval

will be lost and the first interval written to the new file will start at 12:00.

You should be aware that In-Day times do not take effect until the counter first begins data collection according to the

Start Mode (which can be Now, Midnight, or at Date & Time). Until the very first file is opened according to all other

counter settings, the In-Day Times will have no effect.

To Setup a Counter to use In-Day Times:

1. Link to the counter with Centurion software and go to the main link screen. Select the Configure System option

and setup all counter system parameters.

2. Select the In-Day Times function and select the number (0 to 4) and the times of all In-Day Time periods. Note

that you must enter the times in order from the earliest to the latest.

3. Select the Start Collecting function and setup, test, and begin data collection.

That’s it. After the very first file is opened, the counter will then begin to check the In-Day Time settings to see if any

specific time periods in the day have been tagged for data collection.
