How to Use a Pressure/Vacuum Attachment with a Multimeter

How can a pressure/vacuum attachment be connected to a multimeter to measure pressure or vacuum?

a) COM and VΩ b) VΩ and mA c) COM and mV d) COM and A

Answer:

The pressure/vacuum attachment for a multimeter is connected to the COM and VΩ jacks.

When setting up a multimeter to measure pressure or vacuum with an attachment, one would typically use the common (COM) and voltage/ohmmeter (VΩ) jacks. These jacks are standard on multimeters, where the COM jack is used as a ground reference and the VΩ jack is used to measure voltage or resistance which would be related to the pressure in this case.

It is important not to confuse these with the jacks used exclusively for measuring current (mA and A) because those are intended for different kinds of measurements.
