Analogue Multimeter
An analogue meter moves a needle along a scale. Switched
range analogue multimeters are very cheap but are difficult
for beginners to read accurately, especially on resistance
scales. The meter movement is delicate and dropping the
meter is likely to damage it!
Each type of meter has its
advantages. Used as a voltmeter, a digital meter is usually
better because its resistance is much higher, 1 M
or 10 M ,
compared to 200
for a
analogue multimeter on a similar range. On the other hand,
it is easier to follow a slowly changing voltage by watching
the needle on an analogue display.
Used as an ammeter, an analogue multimeter has a very low
resistance and is very sensitive, with scales down to 50 ľA.
More expensive digital multimeters can equal or better this
performance.
Most modern multimeters are digital and traditional
analogue types are destined to become obsolete.
