A ramp digital multimeter operates by generating a linear voltage ramp that is applied to the input signal. The multimeter measures the time it takes for the ramp voltage to match the input voltage, which is then converted into a digital reading. This method allows for accurate and fast measurements of voltage, current, and resistance. Additionally, ramp multimeters often feature high precision and can capture transient signals effectively.
When testing the current draw your digital multimeter should be set on the current.
Unfortunate.
Not overload the meter.
The only different is one has a needle, the other digital numbers-same as with analog and digital watches.

The analog multimeter has a wider range.

In Digital multimeter we use 9V Dc battery.

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.
