what type of multimeter shud i buy. what to look for. what features to look for (like inbuilt capacitance meter, transistor tester etc). i m basically a software engg. so dont have much experience with multimeters.
I was assuming an analogue meter which was a 50uA meter with series resistors for the voltage ranges, and shunt resistance for the current ranges. Those meters (the most famous in the UK being the Avo 8 series onward) had an input resistance which varied with range - being 20,000 ohms/volt on voltage ranges.bogdanfirst said:well i consider the digital superior to the analog. but it isnt fast enough. if the value changes very fast you wouldnt see that very well on the analog,
but the analog has a high input impedance, some have 10Mohm!!!(but are expensive), but typical is 1Mohm.
y advise all to buy a digital, but have a small not so perfoemant analog too, because you might need it sometimes.
