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

1Inspect the Counter for any damage.

2Make 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.

3Connect 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.
