DESCRIPTION
Test and measuring instruments, such as oscilloscopes and
digital multimeters, can be easily damaged
if excessive voltages are applied across their input terminals.
Simple and effective overload protection can be provided by
connecting a high-voltage PTC thermistor in series with the
instrument; see Typical connection of the PTC thermistor for
digital multimeter protection drawing. Under normal
conditions, the resistance of the PTC thermistor is low, so the
test voltage will be measured by the instrument. Under an
overload condition, the PTC thermistor will switch to its
high-resistance state, absorbing the overload current and
protecting the instrument. When the overload is removed,
the PTC thermistor will return to its low-resistance state,
ready to resume its protective function.
