BS 0.10 Model of the human body
By way of the incorporated electronic measuring circuit,
the occurrence of shock currents is indicated by a signal
lamp within the head of the model of the human body lighting up.
A value of I/M in excess of 20 mA with a permanent maximum
permissible touch voltage of 50 V AC is specified as a shock current.
A change-over switch allows to select a contact resistance of either 470 Ohm or 22 Ohm.
The incorporated resistors are protected by thermostatic switches. The operation of these switches is indicated by a signal lamp.
