Multi Tester Quiz

What is the primary function of a multi tester?

• To measure temperature

• To measure frequency

• To measure capacitance

• To measure voltage, resistance, and current

Answer explanation

The primary function of a multi tester, also known as a multimeter, is to measure voltage, resistance, and current. It is a versatile tool used in electrical diagnostics, making this the correct choice.

Which part of the multi tester indicates the measured values?

• Test probes

• Scale

• Pointer

• Adjustment screw

Answer explanation

The pointer on a multi tester moves to indicate the measured values on the scale. It provides a visual representation of the readings, making it the correct choice for indicating measurements.

What does the range selector knob do?

• Adjusts the brightness of the display

• Indicates the voltage level

• Selects different functions and ranges

• Shows the battery level

Answer explanation

The range selector knob is used to select different functions and ranges on a device, allowing users to adjust settings according to their needs. This is essential for accurate measurements and functionality.

What is the purpose of the zero-ohm adjusting knob?

• To zero-in the pointer before measuring resistance

• To select the type of measurement

• To measure high voltage

• To connect the test probes

Answer explanation

The zero-ohm adjusting knob is used to calibrate the meter, ensuring the pointer reads zero before measuring resistance. This is crucial for accurate resistance measurements.

Which lead is considered the positive connection in a multi tester?

• Blue meter lead

• Green meter lead

• Black meter lead

• Red meter lead

Answer explanation

In a multi tester, the red meter lead is designated as the positive connection. This is standard across most multimeters, where red indicates positive and black indicates negative.
