Continual measuring
Posted by Martin Klompjan on 15th Jul 2010
Q: Is it possible to measure constant using a usb cable and PC? Our will the meter stop if the memory of the meter is full. If so is it possible not the press the rec-button on the meter but grap the db(A) value from the sreen fot example every second ( I have a program that can grap values from the screen and write it to a file)
Thanks, Martin Klompjan
A: The unit needs to be in record mode to gather the data and to prevent auto power off. Once memory is full recording will stop.
