Agilent 53131A/132A/181A Operational 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.
4 Press POWER key to turn on the Counter.
