- Page 19 Touch Voltage calculation on the instrument screen can be selected from the list of parameters. Fault current in the equation is a manually inserted value of the predicted power of a lightning strike, e.g. 50 kA. Combined with the body simulator A 1597, the measurement will be scaled to the potential risk around lightning systems.
