Press the
V2
softkey, then position the V2 cursor to the baseline.
The
∆
V value at the bottom of the display should be within the test limits of
table 4-4. If a result is not within the test limits, see "Troubleshooting the
Oscilloscope," on page 4–40.

Continue checking the voltage measurement accuracy with the
remaining lines in table 4-4.

Disconnect the power supply from the oscilloscope, then repeat
steps 1 to 7 for channel 2 (channels 2 to 4 on the HP 54601B and
HP 54602B). On the HP 54601B and HP 54602B, channels 3 and 4,
check the 0.5 V/div and 0.1 V/div range only.
