I have now used the General® UltraTech™ Fraction+ model #1433 3-inch digital caliper (UPC 0-38728-01433-7) a few times and am not impressed.
The first thing I did was use it as a converter.&npbs; I needed to know how many millimeters in an inch. Because the tool does not have a fine-adjustment wheel, I kept missing the 1-inch mark. It took several minutes to finally coax the decide to exactly 1 inch. Those are minutes I will not get back.
Later, I needed to determine how wide something was. I opened the calipers and used the outside jaws to place them. However, I forgot to turn the unit on, so I pressed the on button and remeasured. The number that appeared was much smaller than what the piece looked like. Fiddling with the caliper, I noticed that there was sometimes a negative distance. I turned the unit off and on again to confirm my suspicion. Sure enough, the unit starts at zero no matter how far the caliper is spread.&nbps; To get a true measurement, one has to close the caliper and zero it out, just like taring a scale to zero. Hence, every time I use the caliper, I have to press it closed and hit zero before measuring. This is a little bit of an inconvenience and, therefore, an annoyance.
I will post again when I have used the item more.
