User questions & answers

Question:	near the mm/inch button there is another compartment that opens, anybody knows what it is for
Answer:	Other than the battery, the other compartment is for an RS-232 interface. This interface is for programming &/or data acquisition, proprietary interfaces that only the manufacturer have.
Question:	could I use this to measure nut size so as to get the right socket
Answer:	Yes, you can. Measure the diameter of the nut from one flat side to the opposite flat side. That will be the size of the nut.
Question:	What is the measurement range? I need to know the very smallest inside diameter it can measure as well as the largest
Answer:	The smallest inside will depend how deep you go, but close to surface I would say 1mm or even less. It goes up to 150mm.
Question:	What is the smallest inside measurement it can make
Answer:	Approximately .5MM but not deep. To go to depth of jaws about 6MM. Hope it helps.

User questions & answers

Question:	can i use this to measure screws? i mixed up a bunch of screws in a bag and have no idea what size is which
Answer:	Yes, you can use this device to measure screws. You can check both the diameter of a screw and its length. You should know that some U.S. diameters are not given in ordinary length units. For example, sizes 6, 8 and 10. In order to classify the unknown screws, you could just get some known screws, measure them and write down the diameter of each of the known diameters, then compare the unknown ones with the figures you wrote down. On the other hand, length of screws in the U.S. always seem to be measured in inches, so you can set the caliper to read out in inches. You will have to translate, for example, 1.500 inches to 1-1/2 inches. However, the decimal numbers are seldom exactly what you expect. You have to assume that the numbers might vary by up to about 1/64 inch (about 0.016 inch).
Question:	are these tips hardened? Thanks
Answer:	Yes, the tips are hardened so they don't flex and dull out.
Question:	What kind of batteries do these calipers use
Answer:	Copy and paste this - 50 357 Alkaline Watch Batteries LR44 AG13 SR44W Battery - for a lot of 50 battery cells that work for this Caliper.
Question:	Does this item come pre-calibrated? Will you be able to provide document on the calibration
Answer:	You cannot trace the calibration back to the NIST. If you crave calibration, then calibrate it yourself against a calibrated set of gages. You can't buy calibration for this price range.

Question:	States Item weight 12.5 oz. Is that the weight of the caliper or the caliper and storage box/shipping weight
Answer:	Thank you for reaching out to us about our digital caliper! Average Battery Life : 365 days
Question:	Where is the battery chamber? How is the battery changed
Answer:	The description and box that it came in states, "CARBON FIBER COMPOSITES" and "MADE OF EXTRA STRONG CARBON FIBER COMPOSITES". It is not metal. No part of the calipers is metal. All of the black material that you see in the photos is black, non-metal material and presumably resin-based with chopped carbon fiber strands mixed in. It's made in China. If you need a tool for frequent, durable, long-lasting professional use I would recommend that you seek one made of metal. This device seems reasonable enough for light-duty infrequent use.

User questions & answers

Question:	What is the screw driver for
Answer:	Thank you very much for your interest in our product. There is a battery compartment on top of the digital caliper. You can replace the battery manually directly. We have also mentioned in the picture and you can refer to it.
Question:	Where is it made
Answer:	I would assume you use the included screwdriver on the screw in the back, but you'll probably need a better one, since I couldn't get a good enough grip
Question:	Where is the battery installed
Answer:	To answer directly NO.. it is approx. 5.5" long. But the Tracker 2 HD is not rated for recoil and also any Thermal Camera / Device can not be used behind any regular optic because normal glass is Opaque to Thermal (the lenses in thermal camera's are made of special material that allow long wave infra-red or heat signatures to pass through it unlike normal glass), FYI if you wanted to mount the Tracker 2 HD on a rail the narrow portion of the body is 30mm diameter.
Question:	How do you open the battery compartment
Answer:	No
