Voltmeter of internal battery resistance is mainly
used to measure battery terminal voltage and
internal resistance. The internal resistance is
measured with the international standard AC
signal (1000Hz±10%) by means of four-wire
method to ensure the impact of the test probe
of the contact resistance of the instrument, the
wire and battery output terminal on the
measured value, and the battery voltage can
also be measured at the same time. It is
applicable for measurement of internal
resistances of Lithium-ion, nickel-hydroxide,
lithium-manganese ,lead-acid and other single
cell or all kinds of assembled battery.
