More experimenting with the black light CFL, this time featuring a couple of multimeters I use in my electrical and electronics diagnostic work.

The analog meter on the left, which I purchased in 2018, is a budget model that I bought, because with a digital meter - especially on alternating current (AC) - voltage fluctuates, thus making it difficult to get a clear reading. An analog meter helps eliminate this inconvenience.

The digital meter on the right, which I've had since my senior high school year in 2008, is no longer in my collection due to a broken display; it broke after a nasty fall. Otherwise, it was a very reliable meter with a back-lit display and a socket for testing transistors, features I'd never had before on a digital meter. Its successor is a digital multimeter with a current clamp that reads AC amperage through induction, which is safer than wiring the meter in series with the wire being tested.
