For most instruments, connecting a modem directly to the instrument enables fast routine tests and problem solving investigations to be carried out on-line. Because there is no connection to a PC, this unique concept does not allow manipulation of user data or reduce network security. This concept was pioneered by PANalytical in the analytical sector, and has progressively been expanded in both geographical spread and the range of functions available.

Periodic maintenance checks can be scheduled to run at times when an instrument is not in active use, eliminating unproductive down-time. By monitoring instrument performance, potential problems may be detected and rectified before they cause any unplanned interruption of analysis.

Should a problem occur, the modem connection can also be used to make a first line diagnosis. Often, telephoned instructions enable customers' own personnel to correct the fault. And if the services of a PANalytical engineer are required, he can be sure of arriving with any necessary spare parts.
