Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to measure dc offset [title] Purchase a multimeter. [step] A multimeter is a handheld device for measuring electrical current, resistance, or voltage. Multimeters are available in either digital or analog models, and can sport a variety of different features.

Ending1: The important consideration when choosing a meter to measure dc offset is the lowest available voltage range. [substeps] Because dc offset readings will be quite small (usually under 100 mv), you need a meter with a small range (sensitivity) so that the readings will register correctly. Ending2: Multimeters tend to be very hand-operated and can be purchased at most hardware stores, supermarkets, and electronics supply stores. [title] Inflate the multimeter to determine the current you are calculating. Ending3: Handheld multimeters generate a voltage range of at least. 0 to 1.8 ppm per volt. Ending4: Simply purchase a multimeter that's actually an meter, and read the manufacturer's instructions about manufacturing and how to calibrate it. [substeps] At most sporting goods stores, the first-line meter measures ac voltage.
