5.4 Using batteries to reduce interference
When the AC mains are disturbed by the strong interference signals, you should use batteries. By
using batteries, you can cut off the interference signals in the AC mains effectively, and other external
interference signals will not influence the instrument. When you work in an outdoor place, you should
prepare spare batteries.
5.5 Switching the display modes
In the normal display mode as shown in Figure 5-1, press full screen, the echo display will be
enlarged to the entire screen, at this point, the main menu and the submenu are hidden as shown in
Figure 5-2. In the full screen mode, except the functions of automatic gain, wave peak memory, and
freezing are available, other functions will be locked and unavailable. This feature is helpful to prevent
maloperation when the detection is on site. If you want to return the normal mode, press the full screen
again. After the instrument has been calibrated, and when you start detection, you can switch to the
magnification display mode to observe the echo conveniently.
5.6 Peak value memory function
When the function is enabled, the screen will record the highest point of the echo and joint all the
points with dashed line to form an envelope line, when a higher echo emerges, it will refresh the memory
