◆ Programming explain There are three buttons in meters,such as " SET","←","→" 、" ". "←" ： Menu items on the move or incremental value. . "→" : Menu item down or diminishing value . "SET": Menu Editor or the value of bit shifted to the right (in the digital input mode) . " "： Used for menu moving backward, the parameter is set back off and save your settings .
