Although not guaranteed, most indicators will
continue to function normally with an input current
between 1.8mA and 4mA, at lower currents the
instrument will display ‘LPLo’ before it stops
functioning.
Under or overrange of the BA524E bargraph is
indicated by an activated arrow at the appropriate
end of the bargraph and a flashing bargraph scale.
