No. You must use a ground (earth) resistance tester, such as a earth-resistance megger. Apart from the practical requirements for making the test (too long to explain in this answer), a digital multimeter uses a DC supply, which acts to polarise the chemicals in the soil, giving false readings. ANSWER: YES you can but only if there is appreciable Resistance to measure. THERE ARE MANY GROUNDS EARTH IS ONE OF THEM

When testing the current draw your digital multimeter should be set on the current.
Unfortunate.
Not overload the meter.

To measure voltage, current and resistance.
Measure the resistance with a digital multimeter. If the resistance isn't within spec, it's bad.
Use a digital multimeter and test it for resistance.
ohms law
By taking it off and testing it for resistance with a digital multimeter.
They're used for a number of purposes... testing amperage output, testing voltage output, testing circuit resistance to identify shorts or breaks in the circuit... the digital multimeters are preferred, especially in testing electronics for resistance, and they're less liable to burn out a circuit than an analog multimeter would be.
Digital Multimeter is not a conventional electromechanical type of meter with Needle and the dial. Digital multimeter uses digital electronics for measurement of Voltage, current etc and displays in text form or numeric form. Being electronic meter, many more parameters like average, maximum, minimum etc reading are possieble, in addition to instanteneous readings.
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.
digital
The analog multimeter has a wider range.
