If a digital multimeter is faulty, start by checking the battery, inspecting the test leads for damage, and confirming the fuse inside the meter is intact. If it still gives incorrect readings, stop using it immediately and have it calibrated or repaired by a qualified technician. In many cases, replacing the unit is safer and faster.
You can get reliable, certified replacement multimeters from Enrgtech.
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.
Parts of a digital multimeter include an LCD display and range knob. There are also common ground, positive voltage terminal, and positive current terminal.

A: A VOM digital requires to have a ADC analogue to digital converter whereby the analogue input will be displayed as number representation. An analogue meter all it requires is to have is current flow through it.
'Multimeter' and a 'VOM meter' are different terms for exactly the same thing -a meter that can be used to measure voltage, current, and resistance. These meters can be either analogue or digital. Analogue instruments are now being priced out of the market by digital meters, due to the manufacturing costs of analogue instruments. Digital meters are more rugged and easier to read than analogue instruments, but not necessarily more accurate.

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.

Not overload the meter.
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.
