Personally I do not use analogue meter to test resistor as the result shown
on the meter panel only makes you have to guess what the resistor value
is. You may ask yourself, is it 47 ohm or 47.5 ohm or even 47.7 ohm? By
using digital meter the LCD display in your meter will show you the
exact value of the resistance under test. It is more accurate than using
analogue meter.
First, select the Ohm range and place your test probes across the two
points of the resistor as shown in the photo. Digital meter does not need
any calibration compare to analogue meter where you have to adjust
the adjuster to make it zero Ohm before you begin to do measurement.
The result shown at the LCD display of the digital meter is the exact
resistance value of the resistor.
Digital meter really removed all the guess work! Not only that, many
digital meter is auto range thatÂ’s mean what ever value of resistor you
want to check it will automatically prompt you the result without having
you to adjust to a suitable range in order to test the resistor. This saves
time and accurate too!
