1 AN OVERVIEW
1.4.1 Storage capacity in Computer
Storage capacity in your computer can readily be calculated. The amount of
free space on the disk that will store your measurement data is the limiting
factor.
A 3½" disk will store more than 1,400,000 bytes. This is sufficient to store a
total of 700 000 values.
If we now consider a case where you sample and store 5 channels per second
the following formula applies:
Measuring time = 700 000/5 = 140 000 seconds or almost 40 hours. This time
is naturally multiplied by five if you only use one channel.
Another example: this storage space can be two measurement rounds, each of
two channels every other millisecond for a total duration of 700 seconds (or
nearly twelve minutes).
The formula you use is: interval*storage capacity divided by 2 and the number
of active channels : I*S/(2*C).
Apply this to a hard disk, and you will find that storage space will last a very
long time.
Remember that total storage time in a disk is the sum of all recordings. You
just have to allow for a header space of 16k bytes.
1.4.2 Storage Capacity in the PC-Logger 3150
Storage capacity in the PC-Logger 3150 itself is calculated almost in the same
way as it is calculated in the on-line case.
Three sizes of memory can be supplied: 64k, 64k+512k or 64k+1M.
Every value stored uses two bytes, so the formula in the previous section can
be used here too.
An example: having 64k memory, you want to measure four channels 10
times every second. The interval is 0.1 seconds.
The formula will then be: 0.1*64,000/(2*4)=800 seconds.
Note:
The internal memory of the PC-Logger 3150 will only store one recording at a
time. Starting a new recording will erase the previous one.
Recordings have to be transferred to your computer before loading new
parameters or starting new measurements.
