N8130 can measure the charging capacitance and discharging capacitance of supercapacitor. The test method is as follows: charge or discharge the measured supercapacitor under CC mode, record the time and voltage during the charging or discharging process, and calculate the capacitance by calculating the slew rate of the voltage and time during the process.
Users can choose voltage and time for calculation according to various measurement standards, such as IEC.

Life test
N8130 can measure the physical parameters of the supercapacitor during the repeated charging and discharging process and extract its attenuation curves. By analyzing the parameters and curves, users can obtain the expected life of supercapacitor in different application environments, charging and discharging cycles, and performance index at different stages. Life test results can be used to improve the materials, craft, storage and many other links.
Four-wire sense
During the supercapacitor test, a large current will be outputted, which will cause a voltage drop in the leads and affect the measurement accuracy. N8130 series adopts the four-wire system sense and directly acquires the voltage at supercapacitor output terminals to avoid voltage loss and ensure the measurement accuracy.
Test fixture
Considering the test application scenarios of different scales, NGI provides two types of test fixture: Kelvin clamp and 12-channel special fixture. Both test fixtures support four-wire connection.
Application software
■ N8130 software adopts a platform design, which allows users to customize the test process according to their requirements.
■ N8130 is designed with power limit circuit and has fast response, which can prevent N8130 from being damaged due to over power.
■ N8130 adopts shielding technology, which has wide adaptability to harsh test environment, and improves the anti-interference ability.
