Note: 1. The “rdg” stands for “reading value.”
2. The accuracy is guaranteed for the input frequency range of 40 Hz to 1 kHz (except for
æ
and
å
ranges of AC current input) and
the ambient temperature of 23
±
5
°
C.
If the actual input in each of the following measuring ranges is 10% of the maximum value or less, the following accuracy values
will apply.

3. When using a DC voltage input model in the
ä
and
ã
range, do not open the input terminals. The input terminals can be opened,
however, if a resistor of approximately 1 M
Ω
is connected to the input terminals.
