10.4 Technical Information
The normal mode of operation of the calibrator is with the unit switched on.
When the LED indicates the unit is switched on this produces the greatest radio
frequency emissions.
The calibrator continues to function after exposure to contact discharges up to 4kV and
air discharges up to 8kV, for both positive and negative voltages relative to earth
ground.
The calibrator conforms to IEC 60942:2003 for a modulated root-mean-square
electromagnetic field strength of 10 V/m.
The maximum susceptibility to power and radio frequency fields is with the cavity facing
away from the emitter with the battery compartment facing the table, the antenna
polarisation horizontal and the calibrator switched on.
