What is a Digital / Analog Multimeter?

There are two common digital / analog multimeters.

1. Digital / analog hybrid multimeter.

This type of multimeter adds 7/2 digits to the analog multimeter.



Digital / Analog Bar Chart Double Display Digital Multimeter.

The children of this multimeter are used to observe the analog amount of continuous variation (such as the change in UC during capacitor charging and discharging). Typical products include DT96OT (7/2 digit / 41 bar), 2 BY1935 (15/4 digit / 31 segment) and EDM83B (19/4 digit / 43 segment).

The simulated bar chart has two meanings.



(1) It is determined as a continuous variation analog.



(2) The measured variation is simulated in the form of a bar graph. Bar charts, also called bar charts, can play the role of pointers. The simulated bar graphs are divided into the following three categories:

1 liquid crystal (LCD) bar graph.

The liquid crystal (LCD) bar graph is an intermittent bar, which has high resolution, low power consumption, and low voltage drive, which is suitable for battery-powered miniaturized equipment. The disadvantage is that it is not easy to observe at night.

Amber Plasma (PDP) Optical Column Display

The advantages of plasma (PDP) optical column display are self-emission, high brightness, bright display and long viewing distance, but the disadvantages are high driving voltage and large power dissipation.



LED The LED array consists of high-intensity, low-cost multiple light-emitting diodes, but the consumption of power is limited.
