IET 2220 Overview
- Microvoltmeter Mode with ranges of 50-0-50 µV and 500-0-500 µV.
- Conductivity Mode is a threshold resistance tester for resistances below 75 ohms.
- Signal Trace Mode has 600 kHz signal injected into the two shorted modes via the two clips.
The General Radio 2220 Bug Hound Microvolt Meter is a completely self-contained instrument designed to take over where the automatic board-test systems leave off. Modes of operation include the Microvoltmeter mode, Conductivity mode, and Signal trace mode.
