Set the charging voltage to 2 times the rated voltage of the capacitor under test. Select appropriate charging and discharging time on the thumbwheels provided. Select appropriate value of the inductance depending upon the rating of the capacitor as provided in the specification. Now by pressing the ‘Start Switch’, testing can be started and the presence further of the operator is not required.

The display indicates the number of discharge cycles. The equipment gives beeps after 1000 discharge cycles are over. In case the power fails before the capacitor undergoes 100 0r less discharge cycles , the count is reset to zero and the entire testing is carried out for a fresh 1000 discharge cycles , once the power is restored. However, if the power fails after the capacitor has undergoes more than 100 discharge cycles, this count is retained and the testing is continued automatically for the rest of the discharge
cycles after power is resumed.

A separate switch is provided to read the last count during power failure. In case the capacitor fails during the test, the power supply is cut off automatically and a buzzer sounds an alarm. The control comes out of alarm when it is reset manually.
