Hi everyone;
I'm working with a CR1000 and CR800 data loggers, and using CR Basic for operation. I am a rather new on programming data loggers and learned that we can sample voltage measurements faster in burst mode. From documents which I was able to find, it seems that burst mode is possible for measurements using multiple channels. However, I could not find any clear explanation (for non-experts) or any example about making measurements in burst mode. I will appreciate any piece of information.
King Regards;

Hi Alper,
Welcome to the Forum.
There are probably several ways to do fast measurements, i.e. burst mode. You can set the CR1000's scan rate to 10mS, that is pretty fast. If all of your measurements are the same type you can use repetitions in the measurement instruction and take those measurements on sequential channels. To use reps you'll need to declare your variable as an array:
Public Measurement(8) '<<<< this is an array
Scan (10,mSec,100,0)
VoltDiff (Measurement(),8,mV7_5,1,False,0,250,1.0,0)
CallTable Test
NextScan
The bold 8 in the VoltDiff instruction is the repetitions parameter.
Hope this helps. If not, please post back with more details about what you are trying to do.

The most recent CR1000 manual(dated 1/09)has a few pages on burst mode (Section 11.13), including an example program.
You can find the most recent manual on our manuals download web page:

Janet and Dana, thank you very very much for your interest. I'll work on what you've suggested.
