Based on the results of the conversion, in the parameter processing block, a logical assessment of the verification result is made and signals are generated that the parameter is within the tolerance or outside the tolerance, depending on which further verification of the control object takes place. The display of the test progress is carried out on the control and display panel.

 The disadvantage of this device is the limited functionality for checking objects, which require adjustment of the parameters.

 The system comprises a control object 1, a switch 2, a stimulus block 3, a converter unit 4, a first parameter processing unit 5, a control unit 6, a control and indication panel 7, a switch 8, a second parameter processing unit 9, a third signal driver 10, a fourth driver signals 11, the second signal conditioner 12, the first signal conditioner 13, the first and second outputs 14 and 15 of the first parameter processing unit 5, the first and second outputs 16 and 17 of the switch 8, the first and second outputs 18 and 19 of the second processing unit of pairs 9 meters, the first, second, fourth and fifth 20, 21, 22, 23 inputs of control unit 6.

 The system operates as follows.

 In accordance with the test program embedded in the control unit 6, stimulating signals are sent to the control object 1 through the switch 2 and the controlled signals are sent to the converter unit 4 from the control object 1 through the switch 2. The conversion result is sent to the first parameter processing unit 5, which is preliminarily from the control unit 6, the necessary initial data and the values of the lower and upper tolerances of the checked parameter are entered. Block 5 makes a logical assessment of the test result and generates a signal at the output 15, if the parameter is within the tolerance, or at the output 14, if the parameter is outside the tolerance. The signal from the output 15 enters through the first signal shaper 13 to the input 20 "Norma" of the control unit 6. Unit 6 performs an automatic transition to the next test. The signal from output 14 goes to switch 8, which works depending on whether the controlled parameter is adjustable or unregulated, which is set by the control unit 6. If the parameter is unregulated, then switch 8 transfers the signal from output 14 of block 5 through output 17 and the second driver 12 to the input 21 "No norm" of the control unit 6. Unit 6 makes a decision about the malfunction of the control object.

 If the parameter is adjustable, the switch 8 transmits a signal from the output of the converter unit 4 through the output 16 to the second block of parameter processing 9. Block 9 makes a logical assessment of the test result within the tolerance for adjustment and generates a signal at the output 19, if the parameter is within the tolerance for adjustment, or at output 18, if the parameter is outside the tolerance for adjustment. The signals from outputs 19 and 18 are fed through signal conditioners 10 and 11 to inputs 22 "No norm. Regulate" and 23 "No norm. Do not regulate" respectively. Block 6 makes a decision: in the first case, about the adjustment of the parameter of the control object, in the second case, about the malfunction of the control object.

 Management of the operating modes of the system, indication of the passage of the control process is carried out by the control panel and indication 7.

 Thus, the introduction of new elements and relationships makes it possible to evaluate the parameter by regulatory tolerances, instructing the operator on the adjustment options in the automatic mode in the control process without performing additional actions and attracting additional funds.
