Programming explain

There are three buttons in meters,such as  " SET","←","→" 、" caozuomianban huiche.jpgcaozuomianban huiche.jpg ".
"←" :  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) .
   caozuomianban huiche.jpg "   ": Used for menu moving backward, the parameter is set back off and save your settings .
