Answer the following statement(s) true (T) or false (F)
1. For the protection of a meter, the range should never be exceeded. 2. On a VOM, the correct alignment is achieved when the mirror image of the pointer disappears behind the pointer itself. 3. Wattmeters generally have a range switch indicating multiplier values, such as X 1 or X 100, which means that each reading taken on the scale must be multiplied by the value indicated on the range switch. 4. The proper techniques of connecting electrical meters should be demonstrated and practiced in a laboratory setting. 5. Always connect voltmeters perpendicular to a load or source.
