11 Jan standard weight calibration procedure

Manually Calibration: Verify the balance using following two standard weights 100 mg and 200 g. Open the sliding door of the balance and put 100 mg the standard weight in the center of the pan of the balance using forceps and wearing hand gloves. This includes all types of laboratories, whether they be owned and operated by government, industry or, in fact, any other organization. A company that pays $2,000 to have an ultrasonic flowmeter recalibrated is most likely not going to be satisfied with a report that says, "We have tested your flowmeter against an approved standard and found that it is not reading properly."
