"Hello, Or fastest delivery Tue, Nov 15 . When IC1 is triggered by pressing switch S3, the capacitor under test starts charging via the selected resistor (R1, R2, R3, or R4) and its output jumps to high state, causing LED1 to go off. Thats a small leakage so the modern capacitor passed the test. We picked this frequency because the miniature transformer (10-1 ratio) was most efficient at this frequency. To measure capacitor leakage current or dielectric absorption one can just build a simple electrometer using LMC6001 or similar op-amp with fA bias current.
