Use a
Digital Multimeter(1)
Once we've set the meter we will without a doubt vicinity
the probes on the terminals on which we have to degree the voltage. Place the
pink lead at the superb terminal and Black Lead at the Negative terminal and
you'll get the price of Voltage. If you opposite the polarity of the cable
you'll nevertheless get the fee but it'll be with a terrible signal, always use
the probes in accurate polarity to keep away from errors. You can degree
voltage of a battery, DC adapter, Phone charger and even the voltage drop
across each element in a circuit whilst debugging applications. The under video
shows you how to degree DC voltage with Multimeter.
How to Measure AC Voltage with Multimeter:
While AC voltage is hardly ever measured using Digital
Multimeter it's far nonetheless vital at locations where AC mains are worried.
To measure AC voltage location the Red lead at V slot and Black lead at COM
slot as shown inside the picture under. Now set the mode by using the use of
the knob, we have to place it at AC voltage symbol (proven in image below).
Normally we will have two tiers for AC voltages, they are 200V and 600V. For measurement
AC voltage in India which is 220V we have to location it in 600V mode as proven
in the photo below.
The measuring system is precisely much like measuring DC
voltage, but here we do no longer have any polarity considering we're managing
AC. The following video shows how to amount AC mains voltage the use of a
Multimeter.
How to Measure DC Current with Multimeter:
Most of the traditional Multimeters will now not have the
option to degree AC current, for this reason we will talk handiest about
measuring DC current, however in case you are seeking out a tool to measure
contemporary Clamp meter. Do not try measuring AC cutting-edge with your DC
multimeter it'd damage the meter completely.
To degree DC cutting-edge the black Probe have to be placed
in COM slot and the red probe should be placed in the A slot as proven within
the photograph underneath. This is finished because contemporary should always
be measured in series. Also be aware that a few meters may have two A slot
based on the variety so make certain to examine the symbol before connecting.
Then we will select the mode by using turning the knob to the dc present day
symbol (shown in image). Again we've levels from 2 hundred micro amps to 10A we
can select the desired range. In the under photo the meter is set to study DC
present day at 2mA.So I am the usage of the equal V slot. But if the present
day is 10A then I ought to have modified the slot.
As said earlier, modern can be measure only in collection
with the burden. So if you want to amount
the current drawn flowing thru any cord, you need to disconnect the wire and
location this meter in collection by way of setting one probe at one stop and
the other at the alternative end. The beneath video indicates the way to
measure the modern flowing via a twine that is powering the LED.
