SAFETY INSTRUCTIONS AND SYMBOLS This manual contains up to three levels of safety instructions that must be observed in order to avoid personal injury and/or damage to equipment or other property. These are: DANGER Indicates a hazard that could result in death or serious bodily harm if the safety instruction is not observed.
SAFETY WARNINGS AND CLEANING INSTRUCTIONS DANGER Opening the cover of this instrument is likely to expose dangerous voltages. Disconnect the instrument from all voltage sources while it is being opened. WARNING Using this instrument in a manner not specified by the manufacturer may impair the protection provided by the instrument.
(±5 V into 50 ) , and wide voltage gain range (X0.9 processing. The 579 combines continuously, - X500) make the 579 useful for many timing variable gain, independently selectable integration applications, including those utilizing low-gain and differentiation time constants (Figs. 1.8 and photomultiplier tubes.
