is tihis device is good to test all major appliances.

Yes. You can't use it for high voltage above 600V, but modern LCD displays don't have any voltages that high in them any more.

Maybe not- unless you want to try the more expensive ones. Sorry - I lost faith in the unit we bought. Very disappointing.

Yes I gave up my auto repair shop I had for 30 years 2 years ago and now I do both my own cars and do alot of home repairs and building maintence along with fixings some cars still and HVAC 110 and 220 electrical and the uni-t is fine . I would check this one out to INNOVA 3320 Auto-Ranging Digital Multimeter ( I just do not know for the price if its a good as the UNI-T61E and if it has the big fat fuse protection . I like the UNI-T because of the auto range and fuse protection Like all my old flukes I had .I would By fluke again But do no think they are worth the money any more with so many others well made units at a lower price.

this was used to test "household smoke detectors" It was effective when used. which is critical if you don't know if an old smoke detector works. Any further specs should be referred to manufacturer. When in doubt, replace smoke detector, and then test

If the appliance has a mechanical on/off switch you'll be fine. Things that have electronic switches do not always turn back on; if you can unplug and plug back in your device without having to turn it back on, these will work.

Yes. It's a nice meter that kept working even though I sent it through the dishwasher. Please do NOT try that stunt yourself. I didn't mean to!!

Use a Non-Contact Voltage Tester prior to touching any electrical component if in doubt

Yes it works for testing GFCI outlets (simulates a 'trip') and also checks any other type of outlet for proper wiring (hot/neutral/ground in the proper wiring spot)

This is a good one to use, but may require a little research on specifics of function. I have enjoyed using mine. It is actually not intended for beginners, but it is a nice device.

You can use your device anytime even when there is no Engine Check or Check Engine light . It won't hurt to diagnose your car:)

Yes it will test for power as well as continuity just make certain to read the directions to confirm the color and sound that goes with each.

It is merely a fancy continuity checker. The cable is plugged into each part of the device. Then you watch LEDs light. If they light in the correct sequence the cable is good -- if not then take a guess, cut off a connector, install a new connector and try again until success. If you want to test routers, hubs and switches you will need a more sophisticated and costly tester.

See if u r too close to phones/appliances, or if a computer is on same electical circuit. Very sensitive!
1974629
Yes it does detect Hardware problems. If it's not booting up, listen to the Beeps to determine the actual problem as this devices just really interprets that data

Yes. that is what I bought it for and I have tested it with appliances. I had a problem with the first unit in that the humidity sensor was 8% off compared to two other humidity sensors I had. They shipped a new one to replace at no expense or even having to ship the defective unit back.

I've no idea for GE tester 50542. This one is perfect for family use. It can be used to test grounding, GFCI outlet, fire/neutral wire, etc.
1384611
Yes , this meter will do this, plus it is capable of using for many other electrical measurements.I really like mine
