Make sure nothing is on the weighing surface. Turn the scale on. When the display reads 0.00 press the CAL button. (here's the trick) Press it again and CAL will start blinking (don't put the weight on yet). Wait until it starts flashing a number at you, on mine it's 100.00. Then place the 100.00 gram weight on the weighing surface. After a few seconds it will say Pass. You are done.
The decibel scale is a logarithmic scale. Scroll down to related links and look at "Decibel - Wikipedia" and "Sound level meter - Wikipedia".
(absolute error)/(full scale deflection) x 100 = % error
A One dollar bill weighs exactly 1 Gram.A Five cent piece weighs exactly 5 Grams.
if the zero of vernier scale lies on the right side of the zero of the main scale , then error is known as a positive error .
Overload error: This occurs when the weight on the scale exceeds its maximum capacity. Underload error: This happens when the measured weight is below the scale's minimum capacity. Zero error: This is when the balance scale does not return to zero after being unloaded or reset. Eccentricity error: It occurs when the center of mass of the object being weighed is not aligned with the center of the scale.
To adjust the calibration of a pocket scale, you will typically need a calibration weight that matches the capacity of your scale. Place the calibration weight on the scale and follow the instructions in the user manual to calibrate it by adjusting the calibration setting until the scale displays the correct weight.
The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.
Any scale will do, but try for a pocket scale with .01g accuracy, at least.
