Specifications
This measurement network conforms to IEC/TR 60990.
Measurement network C conforms to the following standard:
Methods of measurement of touch-current and protective conductor current
(IEC/TR 60990 (1990-06))
By installing on the 3155 and making the appropriate settings from the
screen, a configuration with a body impedance network for OFF, a perception
and reaction network for ON1, and a let-go network for ON2 is established.
