1-14 DATE AND TIME
The control module contains a real time clock
which keeps accurate time despite power inter-
ruptions. It is normally more accurate than the
clock in a PC. Every so often it updates the
software clock in the other modules. A software
clock is less accurate, and it loses its mind if the
power fails. Such clocks are kept in the ana-
lyzer module computers, and also in the Auto-
calibration I/O modules.
Set the clock in the System setup menus under
the Technical level configuration... menus.
See the Autocal module instruction manuals for
details about setting up their timing.
Network variables: I_TIME, C_ TIME
