INA 703 Magnetic field coil
The 3 ranges of the INA 703 are selectable by a respective banana plug (Green/
yellow = Low, blue = 1 Turn, Black = 5 Turns, red = 37 Turns) for better accuracy of
low level magnetic fields.
For each of the 3 ranges a separate coil factor. (The coil factor is available in the
INA 703 calibration certificate and is also labelled on INA 703 terminal unit) needs
to be used.
For more information please consult the NSG 3040 systems or MFO 6501/2 user
documentation.
3.4.3 Connecting to any other generator for IEC 61000-4-8 testing
An INA 3251 interconnection cable is required. Connect the INA 3251 intercon-
nection cable directly from the 4 pole connector of INA 703 to the output of the
generator.
The 3 ranges of the INA 703 are selectable by a respective banana plug (Green/
yellow = Low, blue = 1 Turn, Black = 5 Turns, red = 37 Turns) for better accuracy of
low level magnetic fields.
For each of the 3 ranges a separate coil factor. (The coil factor is available in the
INA 703 calibration certificate and is also labelled on INA 703 terminal unit) needs
to be used.
Make sure that the maximum ratings of INA 703 are not
exceeded – risk of fire.
For Standard compliance testing the generator shall have
a THD<8%, this is not permanently guaranteed when
solutions based on variacs and step down transformers
powered from mains supply are used.
