The CAPWIZ Capacitor Wizard CAP1B by Midwest Devices is an extremely fast and reliable device designed to measure ESR (Equivalent Series Resistance) on capacitors of 1uf and larger "IN CIRCUIT" eliminating the need to remove the capacitor for ac curate tests. The Capacitor Wizard CAP-1B finds BAD caps IN CIRCUIT or out of the circuit!!

Midwest Devices Capacitor Wizard CAP1B

"The " Capacitor Wizard ®" meter is a very useful capacitor analyzer from Midwest Devices LLC. The CAPWIZ Capacitor Wizard CAP1B uses the ESR (equivalent series resistance) method for determining a capacitors' "health". Capacitor testing can be problematic using other solutions. The Capacitor Wizard CAP1B ESR method detects problems with a device due to changes in the dielectric constant or the electrolytic compound drying out and really measures the overall "health" of a device and not just its capacitance value. This is an indispensable piece of test equipment for a system designer or product technician!!!!"
