Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as Figure 1 Shown, the present invention comprises following method steps:

[0024] S1: Use a transmission black-and-white densitometer to detect the detection points on the standard density sheet one by one, and record the detected values;

[0025] S2: Compare the detected value with the value on the standard density sheet, and record the detected points with errors;

[0026] S3: Operate the operation panel on the transmission type black and white density meter, press the menu key to enter the calibration mode;

[0027] S4: After performing the calibration interface, test again the points with errors recorded in S2, and display the actual measured value and standard value on the display screen, where the actual measured value is the value actually measured by the current instrument, and the standard value is to be ...

Abstract

The invention belongs to a calibration method, and particularly relates to an error calibration method of a transmission-type black and white densimeter. Compared with a traditional densimeter, the method has the advantages of being accurate in reading, good in stability, convenient to operate and the like, a user can rapidly and conveniently adjust and calibrate the densimeter according to the standard densimeter on site, factory returning is not needed, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to a calibration method, in particular to an error calibration method of a transmission type black and white densitometer. Background technique [0002] Transmission black-and-white density meter (hereinafter referred to as density meter) is a precision measuring instrument, which is used in industries such as safety inspection, and has high requirements for its reliability. Each density meter is equipped with a pair of standard density sheets with a measurement certificate. When the density meter is used, the standard density sheet should be used to verify the density meter. [0003] When the densitometer fails to pass the verification, the densitometer generally needs to be returned to the factory for calibration. If the engineering unit does not have a spare density meter, the work will be suspended, affecting the progress of the project and causing losses. Contents of the invention [0004] The purpose of the present inven...
