AVOmeter model 9: Essentially similar to model 8 but with international symbols rather than letter markings for the DC and AC switches (Basic ranges to 10 A and 3000 V). 20,000 ohms/volt DC, 1000 ohms/volt AC. [22] (The features of the Models 8 and 9 were combined from the Model 8 Mark V of 1972, when the Model 9 was discontinued).
For example, a meter with a sensitivity of 1000 ohms per volt would draw 1 milliampere at full scale voltage; if the full scale was 200 volts, the resistance at the instrument's terminals would be 200 000 ohms and at full scale, the meter would draw 1 milliampere from the circuit under test. For multi-range instruments, the input resistance ...
A common voltage for medium-size electric lanterns. [19] A voltage for older electric systems of automobiles. Deca-10 1: 12 V Typical car battery [20] Hecto-10 2: 100–240 V Domestic wall socket voltage [21] 600 V Electric eel sends this voltage in an average attack 630 V London Underground railway tracks Kilo-10 3: 2450 V
The International System of Electrical and Magnetic Units is an obsolete system of units used for measuring electrical and magnetic quantities. It was proposed as a system of practical international units (e.g., the international ampere, the international ohm, the international volt) by unanimous recommendation at the International Electrical Congress (Chicago, 1893), discussed at other ...
Moreover, similar types of apparatus will have the impedances lying within a narrow numerical range when expressed as a per-unit fraction of the equipment rating, even if the unit size varies widely. Conversion of per-unit quantities to volts, ohms, or amperes requires a knowledge of the base that the per-unit quantities were referenced to.

A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [ 2 ] [ 3 ] A typical multimeter can measure voltage , resistance , and current , [ 4 ] in which case can be used as a voltmeter , ohmmeter , and ammeter .
