Block 2 Part 2

What causes an overload condition?

Range switch set too low for the voltage being measured

The black lead is always connected to the

Point of more negative potential

Tolerance is allowed because

Multimeters have a small degree of error

When the selected range is too high will show what?

A number with no decimal point or is below one.

The red lead is always connected to

The point of more positive potential

A multimeter can only measure a current when its is

Placed across an open in the circuit

Switch opens for

Current measurements

Overload condition looks like

Digit on left of decimal point is far away

Unknown value for voltage or current

Use highest value or range

During a continuity check, what does infinite ohms mean?

An open wire or connection

Resistors connected in parallel mean

Both resistors will be measured

Continuity measurements for what?

To check for opens or shorts

To measure continuity / or unknown resistance value

The range switch should be set to the lowest ohm setting
