Abstract

The invention relates to the field of electrical measuring equipment and allows to expand the functionality of the device by providing programmable start-up of the device in the remote control mode. If there is a Readiness signal received from the analog-digital converter (ADC) 2 to the information source 6, the latter will enter the code of the measurement limit and the type of measured value that goes to register 4. After the signal is received, Starting from the 6th information on the device is the Readiness signal from the output of the ADC 2 is removed. Duration of the signal delay The beginning of the cycle from the programmable device 5 depends on the limit code and the type of measured value of register 4.

Description

The invention relates to electrical measuring technology.

The purpose of the invention is to expand the functionality by providing a programmable launch of the device in the remote control mode.

The drawing shows a flea diagram of a digital measuring device.

The digital measuring device contains an input converter 1, the first input of which is the first input of the device, and the output is connected to the first input of the analog-digital converter (ADC) 2, the first output of the ADC 2 is connected to the first input of the display unit 3 and is the first output of the device The second output is the second output of the device, the register of 4 limits and the type of measured value Hbij whose input is the second input of the device, and the output is connected to the second inputs of the converter 1 and the display unit 3, programmable delay device 5, the first input of which is a third input device ,, a second input connected to an output register 4, and an output coupled to a second input of the ADC 2. The inputs and outputs are connected to the device The corresponding inputs and outputs the information source 6.

The device works as follows. .

From the second output of the A / D converter 2, the second instrument receives the Ready signal “If there is a Go signal

COMPETENCE source of information 6 YOU

gives the code of the measurement limit and the type of the measured value, which through the second input of the device enters the register of 4 limits and the type of the measured value. After that, the source 6 delivers the measured signal in analog form to the first input of the device and the Start signal to its third input. The Ready signal from the second output of the A / D converter 2 is removed.

The programmable holder device 5 issues a cycle start signal.

with a delay, the duration of which depends on the code of the limit and the type of measured value coming from the output of register 4, and permits measurement of the input analog signal. The input converter converts the measured signal into a voltage signal, an input to the A / D converter 2, the output of which generates a code proportional to the measured signal and displayed by the display unit 3.

At the end of the measurement cycle, the ADC 2 restores the signal Ready-

This means that the device is again ready to receive information.

The programmable device 5 delays can be performed on the serial-exhaust generator G5-56,

provides, in external trigger mode, the formation of pulses with a programmable delay relative to the trigger pulse.
