ESI Model 253 Digital Impedance Meter Repair & Calibration

This ESI Model 253 Autoranging Digital Impedance Meter came with a busted Kelvin clip! After replacing that I calibrated the unit per its instruction manual. A beauty of a unit. *I narrowly avoided losing all of this footage entirely, due to introducing a new microphone cable into my AV setup without doing any testing prior to shooting. Audacity's noise reduction feature saved the day. The noise is still there, but it is way, way down and to my ears, tolerable. Rookie mistake on my part and a definite lesson learned.* https://www.offkafka.com/projects Timestamps: 00:00 A quick note 01:16 Introduction, a mustachioed man, busted Kelvin clip, Belden 9452 06:00 Floating shield, wiring and heat-shrink planning 07:39 Mid-build heat-shrink FAIL, wax string to the rescue! 10:40 Cleaning contacts and plug reassembly 13:30 Testing capacitance and ESR, Peak Atlas comparison 17:49 Cover off, +5V and -5V PS supply checks 21:21 It's a socket! 22:54 Calibration - Oscillator Adjust 25:08 Calibration - Unknown & Range Amp Phase Trim 28:54 Calibration - Quadrature Gate Phase Trim 31:25 Manual entry on Dissipation Factor (D) Alignment 32:16 Conclusion - Wrap-up, Tektronix teal, microphone change (LOL), please subscribe and thanks for watching!
