2 Measurement method

◎ The DC voltage of the constant current/constant voltage source is set to the rated voltage (UR ) .

◎ Set the constant current value of the constant current charging and discharging device specified in Table 1.

◎ Switch the switch S to the DC power supply, and charge it with constant voltage for 30 minutes after the constant current/constant voltage source reaches the rated voltage.

◎ After charging, switch the switch S to a constant current discharge device to discharge with a constant current.

◎ Measure the time t1 and t2 of the voltage across the capacitor from U1 to U2, as shown in Figure 2, and calculate the capacitance value according to the following equation :
