The collector | ==Uses== | ||
The collector voltage can be swept from zero to 1500 V in four ranges. | |||
For the 75 V and higher ranges a [[337-1194-02|plastic safety cover box]] must be installed in the test fixture and closed, otherwise a yellow warning light indicates that the collector voltage is disabled. | |||
Because so many used 576s do not come with safety covers, | Because so many used 576s do not come with [[337-1194-02|safety covers]], some users defeat the safety interlock mechanically or electrically, which is hazardous given the lethal voltages and currents the 576 is capable of producing. | ||
