Application Note
1)
Determination of Primary Resistor Ri
The primary
resistor Ri should be selected to enable the rated input current to
be equal 10mA in order
to obtain an
optimal measuring accuracy.
2) Measuring
Range
The sensors are suitable for measuring a voltage ±10 ~ ±2500V. The
primary resistor should be considered
when selecting the
measuring range in order to keep the temperature heating to a
possible low level and to
guarantee the high
electric isolation property.
