2. 27MG Power Requirements
This chapter describes how to power the 27MG Ultrasonic Thickness Gage instrument
using different power options.
2.1 Power Indicator
The battery indicator is always present on the bottom-right corner of the screen. The
27MG can be powered by three AA-sized batteries, by a computer through its USB
connector, or by a commercially available 5-volt USB power supply.
When using batteries, the vertical bars in the battery indicator indicate the remaining
battery power level (see Figure 2-1 on page 23). Each graduation mark represents
25 % of the power level.
