179 TRMS

The Fluke 179 receives good feedback for its display. Although middle of the road – 6,000-count (or 3 5/6 digit) – it is very sharp and has an excellent backlight. The 33-segment bar graph underneath is super-fast, updating 40 per/s, so erratic signals can be observed in real-time. The display clearly shows the range you’re in as well as displaying useful icons, such as low battery and over-voltage.
