Notes: 1) Operating at ±12 V ≤ U

C < ±15 V will reduce the measuring range

2)

If the customer uses 1 kΩ of the load resistor, the primary current has to be limited as

the nominal. To measure the full defined measuring range, the load resistor should

be at minimum 10 kΩ

3)

Linearity data exclude the electrical offset

4)

5)

6)

Regarding compliance towards IEC 61000-4-3 (IEC 61800-3:2017): variation of the

offset between 390 MHz and 400 MHz with a field intensity of 10 [V/m].
