The calibrations on a syringe begin from the needle side and are marked in a consistent increment dependent on the size of the syringe, notes the Royal Melbourne Institute of Technology. Read the measurement using the side of the plunger closest to the needle.
For a 1 milliliter, or mL, tuberculin syringe, the markings are in 0.01 increments. For a generic 1 mL syringe, the calibrations are labeled in 0.1 mL increments. For an insulin syringe, each graduation is labeled as units. A 3 mL syringe is calibrated in 0.1 mL increments. Both 5 and 10 mL syringes are given in 0.2 mL increments, according to the Royal Melbourne Institute of Technology.Learn More
Latitude and longitude are read in both degrees and cardinal ordinates. The latitude and longitude of New York City, for example, is 40.6700° N, 73.9400° W. The 40.67 represents the distance in a northern direction that New York City is from the Earth's equator. The 73.94 represents the distance west of the Prime Meridian that New York is located; the prime meridian is located in London, England.Full Answer >
To read a multimeter, set it to the appropriate setting, attach the probes, and test the desired device. Many newer multimeters are digital and can automatically find range, but there are some older analog ones still in use.Full Answer >
To read a hydrometer, drop it into the liquid sample you are testing, with the larger bulb going in first. Make sure the cylinder is not touching either side of the container holding the sample. Find the mark closest to the plane of the water.Full Answer >
A 1/32 tape measure can be read by counting how many marks short of a full inch a given length is. For example, if a given length is 8 marks on a 1/32 tape measure, it would be 8/32 inches, which can be reduced to 1/4 inch.Full Answer >
