In figure A, select a smaller value on boundary line.
In this figure, the basic accuracy value A can be obtained by the following
methods:
0.1---When 0.4V
rms
≤V
s
≤1.2V
rms,
the test speed is the value A of medium, slow
and fast.
0.2---When 0.4V
rms
≤V
s
≤1.2V
rms,
the test speed is the value A.
When V
s
<0.4V
rms
or V
s
>1.2V
rms
, the calculation method of value A is as the
following steps:
1.
Obtain A according to the current measurement speed;
2.
According to the current test signal voltage to select the accuracy
