We are now ready to choose the sample rate. There are many choices, (000sec, 10msec,
20msec, 50msec, 100msec, 200msec, 500msec, 1sec, 2sec, 5sec, 10sec, 20sec, 30sec,
60sec)
Keystrokes:
1. To view each of these choices, simply hit the data log button repeatedly to toggle
through each of the settings. Notice that you can remember that you are in the “sample
rate menu” by noticing that a unit of time is always displayed. (milliseconds, or seconds.)
2. To select the sample rate from these choices hit the trigger button. This also brings
you to the area where you will choose the number of samples. There are many choices in
this area as well.
Now view the choices for the number of samples by hitting the data log button repeatedly.
The choices that are available are, 10, 20, 30, 50, 100, 200.
Keystrokes:
3. Select the number of choices that you want by hitting the trigger button. This takes
you to the third area which was briefly mentioned.
After you have chosen the sample rate and number of choices you are now ready to select
how the list of time will be displayed. (Time definition area.) There are 3 choices. The
number 0 means that time recording is off. This is rarely used. Number 1 means that the
time will be transferred as a list counting from Zero up till the last sampling.(Absolute
time.) Number 2 is considered relative time where each time value will be the
instantaneous change of time from the last setting. Don’t be too frustrated if you don’t
follow this. Most of the time you will just leave this at number one for Absolute time.
Keystrokes:
4. Select 0, 1, or 2 while in the time definition area. This is done by hitting Data log to
toggle through the 3 choices and then hit trigger to select the choice that fits your
application. (Most of the time this will be 1 for absolute time.) Be careful when you hit
trigger, some EA100’s are sensitive, you want to make sure you only hit it once.
