Remark The measurement accuracy when A
Z
exceeds 10 % is a
supplementary value.
Excluding the highest and lowest measurement ranges that can be
used with that frequency, the measurement accuracy for a
measured value smaller than half the lower limit of each
recommended measurement range or larger than twice the upper
limit is a supplementary value.
Each parameter value in the expression of A
Z
and P
Z
is listed below. The meaning of the
symbol used when calculating each parameter is shown below.
