Analog bar graphA graphic representation of the quantity under test. This makes go/no-go testing easy, and also allows spotting of fast-moving trends.
All hand-held multimeters have a rate of change of values on the digital display screen 1-2 times per second. The display speed of an analog scale is much faster – typically 10 times faster. Accordingly, an analogue scale will visually better show the dynamics of changes in a particular parameter, i.e. in fact, an analog scale works the same way as a dial multimeter. The graphic scale is also convenient to use for assessing the stability of parameters and transient processes, tracking voltage or current surges, for example, at the output of a power source or the rate of change of current when charging or discharging capacitors or various chemical processes with electronic sensors.
If, when working with a multimeter, you need to track dynamic processes, then choosing a multimeter with a graphic scale is mandatory. An example of a multimeter with a graphic scale AM-1060:
