Frequently Asked Questions

Question: What happens when my DataLogger finishes taking 4000 samples?
Answer: When the DataLogger reaches the end of its memory, it will stop taking samples. The only way to allow the DataLogger to take more measurements is to clear the DataLogger memory and begin taking new measurements.

Question: Something is wrong!!! I have started my DataLogger, but now my DataLogger doesn't seem to have taken any measurements. What do I do?
Answer: Unfortunately if the DataLogger has not taken measurements, then the measurements are not available to download. You will need to re-run your measurements. Be sure to wipe the memory before taking measurements, To do this switch the DataLogger to stop, and press the Reset/Single step button until both lights on the DataLogger light.
