However, any cable longer than two meters may have issues with some USB hubs and computers, typically laptops.) To connect an instrument to the computer, please connect one end of the USB cable to the instrument first, and then the other end to the computer.

    DVANCED EATURES 7.1 Dead Time Correction All pulse counting detectors have a “dead time” in which the detector is unable to register another event. In relatively low fields this is not an issue. However, as the field strength approaches the high end of the detector’s range, dead time causes the pulse rate to become non-linear with respect to the real radiation field.
