ăStep 11:ăRefer to Table 4Ć3 and check actual results against the table
specifications for the setting levels indicated.
NOTE
Specifications are one percent of full scale at each volts/div setting.
Example: at 5 mV/div full scale for 10 div is 50 mV, which gives an
upper and lower spec tolerance of +0.5 mV and -0.5 mV.

NOTE
Up to now, you have been working with trace 1 (Channel 2) and
internal mainframe acquisition measurement channel 1. Use the
following steps to verify the vertical accuracy through internal
acquisition measurement channel 2, using trace 2. (Don't remove
Voltage Source from Calibration Head Channel 2).
ăStep 12:ăInitialize the mainframe as follows:
UTILITY button press...........................................
Initialize (in major menu) touch..............................
Initialize (in verification popĆup menu) touch..................
ăStep 13:ăTrigger the CSA 803A as follows:
TRIGGER button press.........................................
Source (in major menu) touch...............................
Internal Clock (in popĆup menu) touch.......................
