Both Chinese and English menus are available in the machine, which is very convenient to switch with one button.

Sleep and Energy Saving Function

It provides the function of displaying sleep for energy saving, set the sleep time, and when the sleep function is turned on and is not operated for a certain period of time, it will automatically turn off the display or shut down, thus saving energy, and effectively extending working time and life of battery.

More Markers

It provides up to 8 independent markers to display the parameters of the marker position, as well as provide maximum, minimum or peak search. Each marker provides a △ mode to make analysis readings become easier. In addition, the ruler on the left side of the display facilitates the judgment of the analysis results.
