Does it check for polarity.

Yes it does. If you enlarge the display photo, you can see the different wiring configurations it checks printed on the unit.

If you are asking if it shows you that the Hot line and Neutral line are right, reversed or flipped for an AC voltage, then yes. The word "Polarity" is usually referring to a DC supply voltage. This is an AC 120 volt receptacle tester only. The GFCI button, on the tester, is for a Ground Fault receptacle only, and should not to be press while plugged into an standard receptacle. There are three lights that indicate the status of the receptacle. One red and two yellow. There are six status indicated conditions that are on the tester. They are OPEN GROUND, OPEN NEUTRAL, OPEN HOT, HOT/GRD REV, HOT/NEU REV and CORRECT.

Check to see if the batteries are good, and installed properly. There is a diagram for the polarity inside the battery cover

No, it is just to check purity or cleanliness level. It doesn't tell anything else.

Polarity should not be an issue. You can come out of the power supply only one way with the main wire, then into this "jumper" and out. Noting colors (e.g. red to red, ensure they match. If not cut and splicing will be required. Excellent product.

Yes, but be sure you have it wired with the correct polarity- see Joe K.'s response.

It test the polarity etc. of a regular receptacle. It does not trip the breaker in the panel that feeds the receptacle. Hope this answers your question.

Not necessarily. If the test line is not as dark or darker than the control line then it is neg. Not bother trying to analyze negative tests.

Since we're dealing with diodes I'd say polarity needs to observed. The good thing is you no harm if it's not right. It just won't light.

The meter supply with polarity connector, black and red wire, which represent minus and plus. The unit does not work at all if change polarity.i do not know what will happen if connect minus 5 v and plus 5 v. without ground. I assume it will not work or just show something wrong. Also, I take a look on surface mount parts and see that red wire via connector goes to diode. You may order this little thing just for few $ and blew up it under your desire in many different ways.

As shown in the photo, the yellow dial on the Left is the polarity selector. You can select which polarity you want.

I have negative in the middle, however a 470uf 35v electrolytic measures correctly with positive in the middle also. I mostly use my meter for the badly marked ceramic caps in my collection.

This unit measures AC current and voltage and therefore has NO polarity on the CT (current transformer - toroid). Only DC measurement units have a polarity. You can connect either of the CT wires (both green) to either the red or black wire and the same applies to the voltage input terminal block.Hope that helps.

yes this in a momentary switch. and it reverses the polarity up + - down - +

I had the same problem (question). The label on the hour meter says that the connections are polarity sensitive but when using to monitor AC usage, there is no polarity. I communicated with the vendors customer rep., and was told that they had engineered the counter to be able to be used in a AC or DC application, but to save money with parts that had already been labeled, they continued to ship the new design with the old labels. They told me to use the meter (counter) without regard to the plus and minus lables. I tried it and it works.

Yes A negative sign (-) will display on the meter when checking DC voltage and the meter leads are incorrectly placed on the voltage source. When the meter leads are reversed, then the negative sign will not appear.

No, it is not polarized. Most plugs have a wider prong then the other one. This does not, both prongs are the same.

I am guessing "NO" since I originally had the wiring polarity hooked up backwards and didn't have a reading.
