Many can measure both - Vrms (AC) or DC voltage.
A voltmeter would measure the voltage. If you measure the voltage drop over a known low resistance you get a kinda-sorta idea of the power available.
Yes, most DMM are ''average responding", giving accurate rms reading if the ac voltage signal is a pure sine wave. They measure the average of the absolute value of ac voltage and are calibrated so that reading are corrected to that of the rms value of a sine wave.Error occur if harmonic are present.
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
Assuming the DMM is rated to test diodes (not all are), meaning that it presents more than forward drop voltage to the diode, a shorted diode will test nearly zero ohms, usually in both directions.

ohms law babe voltage,current & resistance
A DMM measures resistance by passing a known current through the object you are measuring and reads the voltage. You can then calculate the resistance using the equation V=I*R. R=V/I So for 1mA and a return voltage of 1V the resistance must = 1 KOhm. R= 1/0.001 = 1000 Ohm
With an unknown voltage you should start out with the highest voltage setting on the meter. Doing this reduces the risk of "pegging" out the needle on an analog gauge or overloading the input of a DMM. Most DMM's are auto-ranging though.
The following procedure tests for a short to voltage in a circuit.1. Set the rotary dial of the DMM to the V(DC) position.2. Connect the positive lead of the DMM to 1 end of the circuit to be tested.3. Connect the negative lead of the DMM to a good ground.4. Turn ON the ignition and operate all accessories.5. If the voltage measured is greater than 1 volt there is a short to voltage in the circuit.

When testing a diode with dmm in diode test mode 0.6v is delivered through the device to indicate continuity

I don't know which meter it is I know it one of these expose glitches,measure voltage,record readings,spot trends
current is measured with the meter in series and voltage is measured with the meter in parallel of the load
You can test for voltage in a circuit with the help of voltmeter or multimeter (analog or digital (DMM) ). Vikas Pratap Singh NIT Kurukshetra vps3361@gmail.com
