The digital multimeter (DMM) was developed in the 1950s, with significant contributions from several engineers. Most notably, the first handheld digital multimeter was created by a team at the Hewlett-Packard Company, led by Jack G. McCulloch in 1977. However, the concept of digital measurement devices had been evolving since the earlier development of analog multimeters.
When testing the current draw your digital multimeter should be set on the current.
Not overload the meter.
The only different is one has a needle, the other digital numbers-same as with analog and digital watches.
A multimeter - is a piece of testing equipment used in electronics and electrical diagnostics.
ADC on a multimeter stands for "Analog-to-Digital Converter." It refers to the component within the multimeter that converts the analog electrical signals measured by the device into digital values that can be displayed on the screen. This allows for more accurate readings and easier interpretation of measurements such as voltage, current, and resistance.

The analog multimeter has a wider range.
When testing the current draw your digital multimeter should be set on the current.
In Digital multimeter we use 9V Dc battery.
Mastech MS830L Digital Multimeter is a compact, pocket-sized digital multimeter available online at the affordable price, This meter is convenient for professionals who need to do basic voltage, current, resistance and continuity measurements
A Multimeter is an electronic instrument, every electronic technician and engineer’s widely used piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. There are two types of multimeters: Analog Multimeter: The Analog Multimeter or VOM (Volt-Ohm-Milliammeter) is constructed using a moving coil meter and a pointer to indicate the reading on the scale. Digital Multimeter: We mostly used a multimeter is a digital multimeter (DMM). The DMM performs all functions from AC to DC other than analog. It has two probes positive and negative indicated with black and red color as shown in the figure. there are some best multimeters for HVAC.

A multimeter digital may be found in a hardware store. If you fail to find one in a hardware store you may have to look in specialized electrical stores.
To test an AC capacitor with a digital multimeter, set the multimeter to the capacitance setting. Disconnect the capacitor from the circuit and discharge it. Connect the multimeter leads to the capacitor terminals and read the capacitance value displayed on the multimeter screen. Compare this value to the rated capacitance of the capacitor to determine if it is functioning properly.
