Verification

1

 

 

 

 

 

 

 

 

 

 

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.

 

4 Press POWER key to turn on the Counter.
