analog o digital?


gamit ko kasi sa analog eh Sanwa at Wheeler..

=) sa digital,, hmm wala pa kong mapiga,,,wala pa kong personal na ganyan eh^&_^

diko alam pero may mura kong wheeler binili ko sa deeco noon for 700php yata di ko na matandaan.. makapal at parang ruberize yung plastic nya so siguro di yun mabilis masira..

may dt830b ehehe yun yung mura lang.. quality eh kaw na ang bahala.. na meron sa CDR-king.. 120 ang price yata..

ganun po ba.. gusto ko sana digital ehehe

sige analog na lang magkano po ba yung sanwa..

sulitin ko na po pagttanong heheh

pati soldering iron na rin po.. ano po suggest nyo po..

cd r king hehe ayoko dun.. baka sumabog pag gnmit ko hehehe

sige po thanks sa info.. tri mag browse sa deecoo..

try to research about the thread "Best Soldering Iron" marami ng inputs dun

sa price ng sanwa eh nakalimutan ko na.. teka sanwa ba yun o sunwa? hahah pati ako nalilito na sa mga japekes Cheesy


yung wheeler eh 750 ata bili ko dun last last year nung 2nd year pa ata ako nun hehe ayun pero sa Ace hardware ako bumili nun..nagpabili pala..hehe

i really won't go analog at this moment.
dumaan na kasi ako sa analog.
and really.. it's bulky. compare sa dt-830B china multimeters.
it only cost 100 bucks too! ayus din ang battery life than analog.

a pocket DMM is better choice for beginner.
and i also like the continuity beep. BEEEP. for tracing pcb/protoboard/solderless paths for open connections.

ok din na parehas meron ka

yung digital eh merong LCR din=)

nung nag-aanalog ako, sabe ko ayaw ko ng digital, after some time eh parang nagustuhan ko rin..then later pagnagdidigital ako parang gusto ko  pa rin ng analog.. ewan ko kung baket..

hehe =)

mataas ang loading nang analog tester. meaning during testing makakaaffect yung analog tester sa design... unlike digital multimeters if you probed on a precision analog line eh invisible sa circuit. (i'll be stand corrected)

mas ok ang analog meters sa high voltage, industrial testing, general repairs...

(so far yung super probe ang madalas kong gamit kasi may logic tester, multimeter, frequency counter, and pulse gen. etc..)

una analog ako. pero nasira ko agad. (reverse polarity Fixed, then a high voltage on a low voltage selector.. fixed... finally nabagsak ko. dead) then the DMM... kapag na over voltage.. lalabas lang na out of range. 1 yung nakalagay. kung reverse 1 ulit lalabas.. then.. ok pa din. Smiley

sa mga begginer po na tulad natin, para sa skin mas maganda po ang analogue, lalo na po sa repairing,

marami nang thread dito pati narin pagtest. sa resistor maganda digital. sa capacitor, transistor,diode analog maganda. sa volt naman depende minsan kapag nagbabago yung volt at nde ko maintindihan result analog gamit ko. kapag naman sa mga constant digital gamit ko ex. sa battery digital gamit ko o kaya sa ginawa na project na power supply pwedi digital o analog

sa ammeter mas gusto ko ang analog (sa e-bike namin dati nagkabit ako ng ammeter para ma-monitor 'yung current at makapagtipid din ng konti sa battery. Grin).

pero sa general purpose, mas gusto ko ang digital lalo na sa continuity. may Fluke kasi na 'di ginagamit 'yung tatay ko. Cheesy

i would still insist in digital meters.
but before that. my first meter is analog. the rest is digital.

weight.        = pocket DMMS are precise in these sizes which a pocket analog meter loses as the scale.. scaled down.
precision.     = what you see is what you get.
durability.     = all solidstate design. no moving parts. very rugged.
battery life.  = very low power consumption.
readouts.     = you need to view it on an angle to get the precise measurement. (mirror/needle alignment) unlike a digital lcd.

but for a begginer/hobby use..
you can't beat a 100 peso banketa digital pocket dmm.

depend rin kasi, ex sa pagtest ng capactor leaky open or shorted
sa analog meter
kapag leaky ang capacitor  test forward bias and reverse test nde babalik yung pointer ng analog meter sa infinite.
kapag shorted full reading
kapag open infinite reading ng analog.

sa transistor naman yung paghanap mo ng base emitter at collector napaka accurate talaga ng analog, at pagtest narin if shorted na ang transistor or open

^ on large capacitors pwede ring gawin 'yan sa Digital Meter using the continuity test.

Open - 0.L ang display or hindi mag-beep
Shorted - continuous beep
Leaky - forward - beep then resistance settles on finite value, same sa reverse
OK - forward - beep then 0.L reading (infinite), same sa reverse

noong nasa SMPS design pa ako, 'yan ang una kong test kapag may nasira. test sa bulk capacitor.

yup tama sir. may maganda pang test sa capacitor esr meter parin. nde na mag-forward reverse ng bias at kahit nakakabit ayos ang test Smiley

sa ammeter ko talaga preferred ang analog.

kapag nagre-repair ng wireless devices, madaling makita 'yung defective at hindi. kapag nag-transmit kasi tumataas ang current consumption then bababa ulit. 'yung naghahanap ng receiver, madalas naka-pirmi sa mataas na current dahil nahihirapang humanap. sa digital, hindi nakikita 'yung bilis ng palit ng current, halos parehas lang ang mame-measure sa dalawa.

may mga devices din na on proper operation, nanginginig 'yung needle ng ammeter dahil sa pabago-bagong demand. mahirap i-check sa digital 'to dahil na-average niya.
