Table 3
Theory of Operation
The Main Power Supply Assembly
Turning the line power off and on again resets the power supply to normal
operation if the cause of the overload condition has been removed.
An overtemperature sensor in the main power supply is used to turn off
output voltages if the temperature exceeds the acceptable limit (for example,
if the cooling fan of the instrument fails). To reset the main power supply to
normal operating conditions, turn the instrument off, wait until it is
approximately at ambient temperature and turn the instrument on again.
Table 3 gives the specifications of the main power supply.
