Figure 4-1 Basic measurement accuracy: A
Figure 4-1, in the junction line, can choose a smaller value. Figure 4-1, the value of the basic
accuracy A selection method
is as follows:
0.1（Smaller value）is the value of A ,when V
S
=1V and the test speed is MED or SLOW .
0.2（Larger value）is the value of A ,when V
s
=1V and the test speed is FAST .
Test level correction factor: ArB（See table 4-3）, According to Figure 4-1 select the basic
accuracy A，A multiplied by Ar to get the level correction of the basic measurement accuracy.
Here, Vs is the test signal voltage.
