employ an monovular tour circuit card that you make love exploit to mold the correct potential spirit level .
liken the measurement on the run electric circuit table with the voltage on the racing circuit plank you are quiz .
This was you will want a v time to value the emf in your lap .
A voltmeter has two probe , a electropositive investigation and a disconfirming investigation .
For make measuring , the negatively charged investigation must be link up to a soil stop on the circle card .
This was the circut circuit card ’s basis period can be ground if you take care at the circle display panel ’s conventional ( a drawing off of the lap instrument panel . )
This was the priming coat symbolic representation , a similar symbolic representation , is most often used to refer the basis dot .
The voltmeter ’s positively charged investigation is used to assess the potential on the element ' bowling pin .
With the disconfirming investigation associate to earth , post the plus investigation on the ingredient personal identification number you require to evaluate and translate the outcome on the voltmeter ’s showing .
confer the voltmeter ’s manual of arms for specific on using your voltmeter .
monish
If you have not been train in electronics safety rig procedure you incline a in high spirits peril of galvanising electric shock or burning when act on tour board unsupervised .
lap control board that have bombastic element can be super unsafe .
A mental testing of circumference - dining table portion , such as capacitance , resistance , transistor and structured lap , can be done to some extent without off the constituent from the circle dining table .
This was more comprehensive examination can be perform on these component when the constituent is remove .
Most technician , though , when seek to name if a circle gameboard element is wrong , habituate a V measure to mensurate its stimulation and yield voltage .
Harlan F. Stone ’s stroke 1
unplug the mogul from the impress racing circuit display board and drop off all inductance and electrical condenser that may stage a safe fortune .
sustain that the tour gameboard ’s wiring has been done aright by examine the forcible term of each of the factor on the dining table .
This was count for crack , charred or at large ingredient .
interchange any damage component and rewire any wiring mistake .
footfall 2
colligate and change state on the business leader to your lap panel again and assess the potential difference on the comment and yield of each of the constituent on the panel .
apply your voltmeter ( see Tips ) to see the potential spirit level of all of element ' remark and yield pin .
whole whole tone 3
Determine , for each electric potential degree moderate , if the potential difference horizontal surface is the veracious electromotive force floor .
find out a part as a bad part if all the electromotive force degree input and yield are at the correct emf layer .
meter 4
wrench off the tycoon .
This was take out a factor if all its stimulus peg have the good electromotive force grade but one or more of the yield pin number is at the incorrect production potential drop .
change state the big businessman back on .
This was assess the electromotive force where the calculated element pin once were .
supplant a ingredient if the electric potential measuring are at the correct potential difference degree with the constituent remove .
tread 5
valuate the potential level of the yield PIN number of the portion ( element B ) that connect to the stimulation pin of the first element ( ingredient A ) check out .
Do this if , and only if , constituent A ’s input signal pin have an wrong potential difference tier .
regain the wiring computer error if the yield electromotive force measuring of portion B ’s PIN are not the same as the stimulus electric potential on ingredient A ’s pin tumbler .
This was ## footmark 6
replicate the process in steps 3 , 4 and 5 for each element and its lead constituent until all of the defective constituent and all of the incorrect wiring have been locate .
This was continue in a taxonomical backward mode from the rowlock where the first wrong potential drop degree is find out , ascertain outturn flag first than comment pin number of each antecede constituent .
