(Dumb) Electrical testing question

So confession time. I've never used an electrical multimeter. I don't have the funds to spend on an EMS right now, but I want to be safe when I plug up. So my question is can I use a multimeter to test the hookups before I plug in? This is the one I'm looking at. Etekcity MSR-R500 Digital Multimeter, Amp / Ohm / Volt Meter, Multi Tester w/ Diode and Continuity Test, Red https://www.amazon.com/dp/B00KHP6EIK..._pK8mxb27RACPR
Is it safe to stick the leads into the 30 and 50 amp plugs? I'd rather not find out the hard way. Lol. I understand this won't protect from low voltage or surges, but it's a start, right?

IMHO Electricity and using a multimeter is only as safe as the educated individual doing the measurement.

The probes on the meter you have selected are probably not going to be long enough to make contact of the terminal slot of the 30 or 50 amp receptacle.
The use of a meter to do what you want will only check the voltage at that moment. Whereas an EMS monitors your power all the time.

I would recommend that you start with one of these along with the appropriate adapters to connect to a 30amp plug.

50amp is a little trickier.

Dalebra- thank you for the response. I guess my main concern is reversed polarity, bad ground, etc. that can be checked. I know I ultimately need an EMS, but it just isn't in the budget right now.

Logan- I have 30 amp adapter, but just being honest, if 50 amp is there, I'll use it. It won't take me long to learn how to use this thing. I'm just a little skittish sticking metal objects into high voltage outlets. Lol

X2 on yhe plug tester. With your adapters you can test right up to the 50a receptacle.

They are inexpensive quick and safe. The indicator lights tell you at a glance if there is reverse polarity, open ground, etc.

I use one of these testers. I also have a cheep Sperry multimeter. The one I have I paid about $30 for it. You do not have to move the leads. Turn the dial for AC or DC voltage, amperage, or ohms. Very easy to use. I bought it from Menards. I have had a number of multimeters over the years and like this one the best.
