1.1 Product Overview and Features
The BT4560 is a variable-frequency impedance meter.
This instrument is equipped with a highly accurate voltmeter and a temperature measurement function,
and optimal for quality control of batteries.
This instrument has the circuit conguration with high noise immunity, and thus, can provide stable
measurement even at production sites.
What can the instrument
BT4560 measure?
• The instrument can measure the internal impedance of a battery using
the AC four-terminal method.
(Frequency: 0.1 Hz to 1050 Hz, Minimum resolution: 0.1 µ
Ω
)
• This instrument can also measure the DC voltage (the electromotive
force of the battery) simultaneously.
(Resolution: 10 µV, Measurement accuracy: ±0.0035% rdg.±5 dgt.)
• In addition, temperature measurement, which is important for battery
control, can be performed. (Temperature measurement accuracy:
±0.5°C)
What is the difference
between the instrument BT4560
and the existing battery impedance
instruments?
• The instrument has a simple structure, which does not need a loading
device. It is not necessary to congure a system.
• This is a compact instrument and measurement can be performed
without other instruments or devices.
Can the instrument BT4560 be
used at production lines or sites?
• Optional measurement probes can be extended up to a maximum of
4 m, corresponding to an operating environment.
• This can provide highly accurate measurement with a measurement
conguration that resists the inuences of external noise and contact
resistance.
• The built-in comparator function can perform quality judgment of
batteries.
• PLC control using the EXT. I/O is possible.
Can the instrument BT4560
analyze the internal resistance of
batteries?
• A personal computer with application software connected to the
instrument can continuously measure any frequency in the range of
0.01 Hz to 1050 Hz and necessary points.
• This instrument is able to draw Cole-Cole plots*.
* The Cole-Cole plot is a plot of the frequency characteristics of battery
impedance in which the horizontal axis represents the real part of
impedance and the vertical axis represents the imaginary part of
impedance. This plot is used to evaluate the internal resistance of the
battery.
