Function

In everyday life, often interpreted as a heavy mass, but in a review of physics both these quantities are different. Gravitational mass is unaffected, while the weight is affected by gravity. Function of electric and non electric balance in general is a mass of gauges. The usefulness of this balance depends on the scale of the balance sheet eg / electric scales in supermarkets in the laboratory with a sensitivity and scale of its balance sheet is much different.

The measurement process

In general the balance meninbang with electronic / digital are:

Make sure that the scales are lit.

Make sure the scale shows the number "zero" (if it is not necessary in the correction).

Letakakan object whose mass is to be measured on the disc where the object.

Read the scale indicated on the digital display unit according to the scale of these scales.

For high sensitivity measurements have to wait 30 minutes, because it can only work on a specified temperature limit.

Calibration

Controlling Scales / Balance Sheet

Scales / Balance is controlled by using weights that are attached or with two external weights, ie 10 gr and 100 gr. Scales / Balance electronics, have to wait 30 minutes to adjust the temperature. If a balance is very sensitive, can only work at specified temperature limit. Scales should be protected from movement (wind) before considering the number "zero" must be checked and if necessary do a correction. Weight deviations are recorded on the sheet / card control, which are listed on the sheet the number of times the scales must be checked. If the scales can not be used at all the scales must be repaired by an agent (supplier).

Cleanliness of the scales

Cleanliness of the scales should be checked after each use, parts and weighing should be cleaned using a brush, soft cloth or paper (tissue) and clean the whole weight scales must be turned off, then the dish (pan) scales can be removed and all the scales can be cleaned using cleaning like a soft detergent, mix water and ethanol / alcohol. After cleaning the scales are turned on and after heating, check back with the weights.
