Abstract
An intelligent verification device for a pH meter calibrater comprises a digital acquisition unit, a computer, a high-resistance switch, a special sampling resistor, a display and a keyboard, and is characterized in that the high-resistance switch is in parallel connection with the digital acquisition unit after being connected in series with the special sampling resistor, and the digital acquisition unit is connected with the display and the 8-bit keyboard respectively, and connected with the computer through an RS232 interface. The verification device realizes that the computer replaces the previous cumbersome jobs, such as manual reading, calculating and data processing, greatly improves the work efficiency, has a simple structure and is convenient to operate.
Description
Technical field
The utility model relates to a kind of type PH meter check instrument intelligent testing device of watthour.
Background technology
At present, according to the requirement of < < JJG919-2008pH meter calibrating instrument vertification regulation > >, to the calibrating of type PH meter check instrument, be to adopt import digital voltmeter to examine and determine, calibrating project respectively: zero migration, the current potential error of indication, the pH error of indication, temperature compensator error, stability of display and high resistant device error.Calibrating mode is to adopt the mode of manually calibrating to realize.Common way is by the measuring junction of the output terminal access digital voltmeter of type PH meter check instrument, according to the requirement of rules, operation type PH meter check instrument regulates its output, write down by hand the output valve of type PH meter check instrument and the reading on digital voltmeter, respectively according to formula hand computation mean value and error amount, whether qualified carry out judging after data recondition, provides corresponding calibration certificate or rejection notice of verification.This examines and determine the not only import digital voltmeter of Price-dependent costliness, and manually in verification process, is producing a large amount of data, calculation of complex, and efficiency is extremely low.
Summary of the invention
The purpose of this utility model is just to provide that a kind of work efficiency is high, accuracy good, type PH meter check instrument intelligent testing device of watthour simple in structure.
Type PH meter check instrument intelligent testing device of watthour of the present utility model, comprise digital collection unit, computing machine, high resistant switch, sampling resistor, display and 8 bit keyboards, after being characterized in that high resistant switch is connected with sampling resistor, be attempted by digital collection unit, digital collection unit is connected with display, 8 bit keyboards respectively, and digital collection unit is connected with computing machine by RS232 interface.
The principle of work of type PH meter check instrument intelligent testing device of watthour of the present utility model is: digital collection unit is by the data that collect, friendship display shows, the data that collect are sent to computing machine simultaneously, by computing machine, the data that transmit are carried out to final calibrating data processing.
Type PH meter check instrument intelligent testing device of watthour of the present utility model, has realized the loaded down with trivial details work of computer generation for former artificial reading, calculating, data processing, greatly increases work efficiency, simple in structure, easy to operate.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
Embodiment
A kind of type PH meter check instrument intelligent testing device of watthour, comprise digital collection unit, computing machine, high resistant switch, sampling resistor, display and keyboard, be characterized in by the closure of high resistant switch, by sampling resistor series connection in the line, by the data of exporting on tested type PH meter check instrument, by digital collection unit, gathered, and shown by display, simultaneously, digital collection unit is sent to computing machine by the data that collect by RS232 serial ports, by computing machine, the data that transmit is carried out to data storage, calculating and data recondition.
