Verification
The operational verification is an abbreviated series of checks that may be
performed to give a high degree of confidence that the instrument is
operating properly without performing the complete performance tests.
If you are unfamiliar with the operation of the Counter, you should review
the Chapter 1, “Getting Started,” in the Operating Guide. However, the
procedures in this chapter are written so that little experience is
necessary. The procedures should be followed in the order in which they
appear.
Power-On Self Tests
1 Inspect the Counter for any damage.
2 Make sure no cables are connected to the input channels (rear
and front panels) of the Counter.
NOTE
It is normal for the fan in the Counter to continue to run after the Counter
is placed in Standby mode. Power to the timebase is continuous to
maintain long term measurement reliability, and the fan helps maintain
timebase temperature stability.
NOTE
The power supply will automatically sense the input voltage; thus, there is
no need to change the ac voltage setting.
3 Connect the power cord to the Counter, and connect the other end
of the power cord to the primary power source.
4Press POWER key to turn on the Counter.
