If I have a 0-1 volt voltmeter (10 led bargraph display) and I want to measure a 12 volt bat, would it be safe to connect a Pot. between the voltmeter and the 12 volt bat to reduce the voltage down to 1 v for a full display? Thus my 0-1 volt voltmeter will show full 10 led bars if the voltage is 12 and 5 led bars if the voltage is 6. Is this safe to do? Will I burn anything since the voltmeter is designed to measure 0-1 volt?
