For each DC voltage applied to the DSO input, repeat parts 1), 2), 3) and 4).
Calculate the Difference ( ∆ ) by subtracting the DMM voltage reading from the
DSO mean voltage reading. Record the test result in Table 7, and
compare the Difference ( ∆ ) to the corresponding limit in the test record.
Repeat step 5.7.1.a. for the other channels, substituting channel controls and
Input connector.
5.7.2 Negative 1MΩ DC Accuracy
Recall DC accuracy - 1 Mohm 2mv.lss or configure the DSO as shown in 5.7.1.
Connect the test equipment as shown in either Figure 5-4 or 5-5 or 5-6.
For each DSO Volts/div, set the output of the external DC voltage reference
source as shown in Table 8, column PS output. (if a banana-BNC adapter is
being used it can simply be turned to get the opposite polarity)
