Abstract
The purpose of calibration stress meter is to determine what strain σ or elongation of the scale corresponds to one unit. It is more convenient to express the division value of the strain. The paper proposes to determine the actual price of the scale division of Automatic Meter strain (AID-4) in conjunction with a specific type of strain gage load cell calibration on the beam, and is an order of calculating the average price of a division on stresses σ and the relative deformation ε.
Instead of two resistance boxes and metrological service proposed, developed and used in the process control device efficiency (balancing and calibration).
