4. Key Description:
5. Use manual:
1>. It will display current voltage after power on.The buzzer will alarm If the current voltage is out of setting range(default 4.0V-50V).
2>. Short press ‘key +’ to display upper limit voltage for 5second.
3>. Short press ‘key -’ to display lower limit voltage for 5second.
4>. Long press ‘key +’ to setting the upper limit voltage.Set value by short press ‘key+’ and ‘key-’.It will save automatically after 5second.
5>. Long press ‘key -’ to setting the lower limit voltage.Set value by short press ‘key+’ and ‘key-’.It will save automatically after 5second.
6>. Alarm If the test voltage is not within the setting range.
