motors can use meter current same full-scale deflection range having same sensitivity Obviously such tiny current would bother motor battery However electronic circuits operation would severely

taken lower portions given scale example nominal 30 volts applied read 10-volt scale accura cy reading would given 30 olts grand total plus/minus 10% 3% actual practice Ive never seen such miserable degradation actually occur wary anyway other ways accuracy can speci fied such simply have FS designation illustrated previously example Radio Shack 22-204 multimeter discussed earlier installments miniseries has stated accuracy simply 3% some ranges other values other ranges Such specification means given readinganywhere scaleis within three percent real true value Such much better circumstance average first example general since multimeters offer variety both functions ranges also variety accuracies listed Usually DC voltage current ranges accu rate AC ohms ranges less accurate Agaln different manufacturers spell out different ways sure check manual particulars apply instrument Later well see DMM accuracy specified what means two terms confusing sensitivity Ive seen term used several ways Ill simply illustrate few Some use sensitivity describe load voltmeter places circuit component under test Remember voltmeters re quire some small current own make needle move current comes what being measured measure some thing often change As example some voltage scales Radio Shack instrument have sensitivity 50000 ohms per volt simply describes size value multiplier resistor switched place selector knob set some particular range exam pie 10-volt range example above ternal meter resistor would 50000 ohms per volt times 10 volts 500000 ohms means instrument used range its like placing 500000 ohm resistor across whatever being measured does matter perhaps few volts being meas ured ie pointer does go full deflection ohms per volt remains con stant selected range reflect earlier lessons youll realize what really saying much current needed instrument move pointer full scale example its 10 volts divided 500000 ohms 20 microamps million times less current Elec tric motors can use meter current same full-scale deflection range having same sensitivity Obviously such tiny current would bother motor battery However electronic circuits operation would severely disrupted such measurement burden simple obvious case would occur example example instrument/range used meas ure voltage across 500000 ohm resistor particular instance new total resis tance would become 250000 ohmshalf originaland circuit measurement status would severely changed 100% reading er ror could easily result Finally case accuracy sensi tivity used varies greatly among meters among scales given instru ment check manual its important Sensitivity sometimes used describe 'how little takes make needle move' Used way term similar term resolution applied servos much input signal required make needle ser vo arm move stopped motion direction next slightly-greater position same direction Used way sensitivi ty really description pointer-bearing friction Unless instrument has suffered mechanical damage movement has come contaminated dust like need concern yourself version sensitivity Finally Ive seen two other obscure uses word doesnt matter youve made far through
