You must have a calibration certificate to show calibration results. While the frequency of calibrations depends upon use, the rapid deterioration of accuracy warrants additional troubleshooting. Most people use a nickel to calibrate their scale because it is the most reliable. While the ISA specifically states that tolerance can be in measurement units, percent of span or percent of reading, it’s ideal to calculate the measurement units. Place your chosen coin on the scale and read the output. They … Place one nickel on the scale and note the weight. Furthermore, to properly calibrate the scale in this example, the calibration technician should be using a mass standard with an accuracy tolerance of at least ±0.3125 grams or finer(1.25 grams divided by 4 from the 4:1 ratio).

Step 4. } This document is usually in the form of a metal plate or tag on the scale with the make, model and capacity information. Calibrate if the scale has been knocked/moved around a lot in transit. It is the most common sensor calibration type providing the widest operating temperature range. If you place a quarter on the scale, the output should read 5.670 grams. If you do not use similar weights then you cannot properly calibrate the scale. First, if you are trying to actually calibrate an electronic scale that reads out in 0.1 (1/10th) gram increments, you need to get access to a 100 gram weight that is least Class M2 grade, or several M2 grade weights that add up to 100 grams. It can degrade even quicker if the scale is exposed to electric or mechanical shock or is in a manufacturing environment with moisture, oils, metal chips, etc. Alternately, you can use coins: Pennies made after 1983 weigh exactly 2.5 grams (0.088 oz).
