Answer: 
A small button on side near the sensor turns it on. The on off switch is the weak link of this tool. This tester is not designed to be dropped many times . Have gone thru 5 or 6 of these in the last five years, but when its working it is very good at sensing voltage

Answer: 
There is a very well constructed button that allows you to toggle it on and off very easily. I usually let it cut off automatically as you hear an audible alert when it auto shuts off.

Press and hold the power button for ½ second, then release. Listen for single-beep sound and
watch for a steady green LED to illuminate in the tip of the tester.

Answer: 
Hey dibs, Good question! Knowing your limitations is the first step in keeping safe. As long as you keep yourself from touching live energized parts and conductors, you should be fine. Around the home and shop it has many uses. It only works with AC or Alternating Current. So it should not be used for the downleads of a PV (Photovoltaic) array or the current found in a car. That is DC or Direct Current. Read More
Hey dibs, Good question! Knowing your limitations is the first step in keeping safe. As long as you keep yourself from touching live energized parts and conductors, you should be fine. Around the home and shop it has many uses. It only works with AC or Alternating Current. So it should not be used for the downleads of a PV (Photovoltaic) array or the current found in a car. That is DC or Direct Current. If you want to check for a tripped breaker or blown fause at an outlet, place the probe in the narrow of the two receptacle slots as that is the hot side of a 120 Volt outlet. I always remembered it as "wide is white" or neutral. This is not the case for a 240 Volt outlet as BOTH slots may be hot. Running it along the cord works too. It only picks up the hot, or "live" wire. I use it for miniature decorative lighting to check where the bad bulb is. Sometimes I have to reverse the polarity of the string so to keep the hot side running in series with the bulbs and not on the return side. NEVER use it to check downed power lines. The voltages on those can be in the thousands and will literally jump out at you!! So in general, it can help you to be safe! Hey, if my apprentices can learn this stuff, you can too! Pick up a book or go online to find some electrical training. I have been doing this stuff since the 70's and I am still learning. Read Less

Answer: 
It prevents dangerous situations. When dealing with electrical wiring and outlets (and fixtures), this tool will indicate if there is electricity in the wires. That is invaluable info for the home-owner, non-professional person. You must read the instructions, try the "test' each time, and protect yourself with it.

Answer: 
Howdy dibs,
Anytime you are exposing yourself to working on live electricity there is a danger of harming yourself.
Being that this requires only being near the wires and outlets, it is safe to use for testing voltage.
Happy testing,
Coach Dave

Answer: 
It works by reading the field produced by current. All you have to is first touch it to a cord you know has power- this will let you know tester is working.
Then touch cord (or wire) you want to very is live.

Answer: 
The Klein Tools NCVT-1 will detect 50 to 1000 Volts AC. If you believe you are using the tester properly in this range, you may need to return it for a replacement. Please see the Warnings section in the instruction manual for conditions in which the tester will not or may not detect voltage.

Will the product test an electric dryer outlet if the prongs on the dryer cord are longer than the meter prongs. The meter feels like it is meeting resistance and I hate to force it into the outlet.

Answer: 
It will sometimes detect voltage depending on how sensitive the tester is but most the time you will need to remove the dryer outlet or use a tester will longer leads. Remember this tester detects voltage and will get bleed over thru cords. It does not tell what voltage is present

Answer: 
Some dryer, range, and industrial type receptacles have the contacts located deep inside enough that they are too far away to have the sensor pickup. Try moving it over the cord as it will only sense the "hot" conductors within it's insulation.

Answer: 
The tip should fit easily into a regular outlet, perhaps you are dealing with a tamperproof outlet. This product cannot be forced into such a device. Klein Tools recommends that you consult an electrician.
