User questions & answers

Question:	How do you reset this? It has an old reading that I'd like to clear so its not confused with any new reading.I tried turning it off and recalibrating
Answer:	Coming from a professional pencil salesperson, if you are experiencing a lot of color pencils that are breaking when you are sharpening them, and you are using a single blade type sharpener, most likely your blade is dull and is putting too much friction on the color cores, and snapping them off just inside the wood casing. I would try changing the blade out on your sharpener or purchasing a new sharpener to not waste color pencils. An Alvin brand 9866 or 9868 brass sharpener style is a "lifetime buy" since the sharpener is indestructible, and the blades are cheaply replaceable.
Question:	Does this register carbon monoxide levels lower than 9ppm? Will the display show 5ppm for example or just 0 to 9ppm
Answer:	Sorry, I have not used them with cra-z-art colored pencils. However, I feel they work best with oil based pencils instead of wax based. Cra-z-art may be waxed based?? Sorry...
Question:	The plastic holder cracked. Can I buy a replacement
Answer:	I use oil pencils to add finer details with oil pastels. These work with the oil pencils but you do need to be careful not to go over the oil pastels with the same force you would use on the pencil marks because you can chip away layers of the pastels.
Question:	Does this unit record and save readings
Answer:	Yes!!! I hadn't heard it should but I just tested and I can go through my coloring with a wet brush and nothing happens. Wish I could post a picture for you to see but don't know how. :(

Question:	Can this be left out specifically as an alarm in a camper? Typical home alarms don't work well in small spaces cause they go off too easily
Answer:	Yes, water does tend to get underneath of it so I take it off most of the time but sometimes I use the opportunity to take off the protector and wash it as well.
Question:	I want a device to test my home gas fireplaces at start of season. Is this want I need
Answer:	If I'm understanding your question correctly, yes. You can print anything as long as you have a printer.
Question:	What's the difference between this and the more expensive versions up to
Answer:	Nikki, Derwent Lightfast are oil-based colored pencils. They are NOT used with water. If you are looking for watercolor media, you might want to try Derwent Inktense Pencils or Intense Blocks. If you're concerned with colors fading over time, most of the Derwent products have a good lightfast rating. Hope this helps.
Question:	Can anyone please confirm if it gives readings below 35? ie 1, 8 etc? (important) Manufacture/user have different statements... any owners chime in
Answer:	Go to Derwent’s website. They have a complete color chart that shows which colors are in which size sets. I got there by googling “Derwent Lightfast Colored Pencil Reviews”. As you know, it’s a UK company, but they have a US website. BTW, the largest set available in the US right now is 72 pencils. They apparently have a set of 100 that is available only in the UK but is coming here in the hopefully near future. I’ve been told that this very consumer-responsive company has been kind enough to provide a set of the new 28 colors for those of us who have the other 72 already. Also, if you sign up for Dick Blick’s emails, they have promised an alert as soon as the new sets are available. They won’t deluge you with a million emails a week either. Hope this helps.
Question:	Is this overkill if i a Avg joe who travels a lot? I'm not a pro user, just need a good portable loud alarm for my family
Answer:	Yes. Go to the Derwent website. There is a UK site and an American site, I ordered the newest individual colors from the UK because the individual pencils were nit available in the IS at the time.

User questions & answers

Question:	i'm replacing a 5 year old unit that is marked 12vdc 82ma. all i see for sale is 12vdc 108ma. any problem with this scenario
Answer:	Small potatoes. These ma are small, in any event and i'd go for it. What surprised me is that my old and new - identical - units had the same amperage. Is the old unit real identical to this one?
Question:	How many amps does this pull
Answer:	I dont know, but the wire size is not all that big. Some versions of this are 9v battery powered which also suggests low current draw.
Question:	What is the actual hole size that it fits into?? The measurements shown seem a little larger than the one I need to replace
Answer:	The actual hole size that the back of the unit fits into is 5 1/4 inches by 2 inches. The hole is just a little bit bigger than the back of the unit. The outside front dimensions of the unit are 5 5/16 inch by 2 13/16. The unit takes awhile to actually start working. After installation and applying power the green light will blink for a good while before it goes steady green which indicates it is operating correctly. Do not try cleaning dust and dirt from the unit using a can of compressed air. I did and that is what made mine go bad.
Question:	Is this unit hard wired, and how big is the back ? I am replacing another unit
Answer:	Yes, this unit is meant to be hard-wired into a 12volt system. I'm planning to install it in my travel trailer tomorrow. The section that goes into the wall = 5 3/8"L x 1 7/8"W x 1 3/16"D (front panel that sits on the wall surface ~ 1/8" thick).
