All instruments detect inadvertent

energised to greater than 25 V,
dependent on model, the instruments
either switch to the default voltmeter
or indicate the presence of voltage by
beeping and flashing the display.
Under this condition an insulation or
continuity test cannot be carried out
and the instrument will therefore
automatically inhibit any further
action until the source of voltage has
been removed. Although insulation
