Analog ESR Meter
Long jealously kept electricity scheme for testing electrolytic capacitors, finally the pages of the Emitters.
ESR-meter (Electrolytic serial resistance), an electronic instrument for measuring the degree of freshness (dry) of electrolyte fluid in capacitors, without dislocation of the experimental component of the printed plate.
The device is built in miniature version on the two PCB, in addition to conventional analogue AVO meter (Iskra, Unimer 43) with dimensions 68x23x22 mm.
There is a built in lithium-ion battery as a autonome power source,builtmicroswitchÂ which activates the ESR meter locate on top of instrument.
Two test terminals contactsÂ are also locate on top of the device.
