ITT Metrix MX202 multimeter 1000V, 5A, 2MΩ, 0-55dB

Basic multimeter from ITT. Incredibly old piece of technology. This "small/big scale" multimeter is a classic. No large central switch to change ranges. It has a thumb-wheel on the right side and a vertical "radio scale" (with rope & winch) on the right side. The A-Ω-V scales cover the whole front of the 140x105x53mm instrument.
