Getting Started

Turning the POWER Switch Off

Flip the POWER switch to the ( O ) side to turn the instrument off. When it is

turned off, the instrument interface will prompt “Power Down”, and the instru-

ment will store the setting information before shutdown in the group 1 non-vola-

tile memory.

After you turn the POWER switch off, wait at least 10 seconds after the fan

stops before you turn the POWER switch back on. Turning the instrument on

too soon after you turn it off can cause damage to the inrush current limiter cir-

cuit, as well as reduce the life of components such as the POWER switch and

the internal input fuses.

tions. Briefly:

sired settings.
