With the caliper can be measured internal dimensions, external dimensions and depth dimensions. Testing and measuring equipment are the most important tools and belong on every workbench or in every tool case. You can use it to determine the diameter, core holes measure in diameter and depth or the distance between two threads, so the pitch of the thread. You should pay attention to the following errors during measurement in order to obtain a correct measurement result. Keep the caliper and the part to be measured steady and straight, do not tilt them. Pay attention to your measuring pressure, too strong or weak measuring force affect the measurement result. At best you have a constant reference temperature of 20 degrees Celsius, strong temperature fluctuations change the measurement results. Please check your caliper regularly for damage, quirks, indentations and remove soiling immediately.
Please note the following information on our products: the crossed-out dustbin symbol means that the battery may not be disposed with household waste. The symbols shown on the batteries have the following meaning: Pb = battery contains more than 0.004 mass percent lead / Cd = battery contains more than 0.002 mass percent cadmium / Hg = battery contains more than 0.0005 mass percent mercury.
There is the digital caliper (with LCD display) or the analog caliper (with vernier scale). Advantages of the digital caliper are comfortable and fast reading on the display in metric and inch. Disadvantages of the digital caliper is the power supply (battery empty), they are not dust-proof, waterproof or oil resistant. The advantages of the analog calliper, however, are the insensitivity and longevity. However, it takes some practice reading the vernier scale. The correct reading of the NONIUS SCALE: The measuring accuracy is exactly 1/10 mm, while 9 mm are divided into 10 equal parts, one part corresponds to 9/10 mm. The analog caliper has two scales one on the fixed part and one on the moving part. On the fixed scale are mm, on the movable scale 0.1 mm. Look along the moving scale where a line coincides with a line on the fixed scale. If it is a smooth mm specification, then the dash is at zero in accordance with the upper scale. For example, if you tentatively move the lower scale to the middle of two bars on the upper scale, the result is very likely to be 5, between 10 and 11 mm, then our measurement result is 10.5 mm.
