【Example】

The pulse test apparatus of the present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 shows a pulse test apparatus of the present invention, which is a pulse generator for generating a pulse. It has a raw circuit (1).

[0007] The pulse generation circuit (1) is a multi-dial (which changes the required pulse frequency. 2) and a manual switch (3) for additional output of one-shot pulse, Ideal for testing loose equipment.

[0008] On the other hand, an external pulse input circuit (4) that transmits the external pulse as it is as an input is installed. Be kicked. Next, an output circuit (5) is provided, and the output circuit (5) includes a pulse generation circuit (1) and The pulse from the external pulse input circuit (4) is output to the outside.

[0009] The output circuit (5) has three types of output: open collector output, contact output, and voltage output. Conversion is possible. On the other hand, the pulse counter circuit (6) counts or outputs the number of input pulses. Any of the functions that set the number of pulses arbitrarily and automatically stop the output at the set number of pulses Or, it has both functions.

[0010] The power supply circuit (7) will provide a stable power supply for the device. The above-mentioned pulse test apparatus is, for example, as shown in FIG. 2, a pulse type flow transmitter and an integrator. Connected between them and inputting an external pulse and transmitting to the output at the same time, a pulse type flow transmitter and And the totalizer can be checked at once.

[0011] The example shown in FIGS. 3 to 5 is one in which a pulse is generated from the pulse generation circuit (1) of the device of the present invention. It is generated and output from the output circuit (5) to test various pulse-using devices. It is something.

[0012] That is, the example shown in FIG. 3 generates a pulse from the pulse generation circuit (1) of the device of the present invention. The pulse counter circuit (6) is generated and output by the voltage output of the output circuit (5). The number of pulses counted and counted by the CPU through the CPU I / O device The number of pulses is compared to test the CPU.

[0013] In the example shown in FIG. 4, the pulse is generated from the pulse generation circuit (1) of the device of the present invention. Output by the open collector output of the output circuit (5) Compare the number of pulses counted in 6) with the number of pulses counted in the electronic counter. The electronic counter is being tested.

[0014] In the example shown in FIG. 5, the pulse is generated from the pulse generation circuit (1) of the device of the present invention. Output by the contact output of the output circuit (5) and count it to the pulse counter circuit (6). Test the integrator by comparing the number of pulses counted and the number of pulses counted by the integrator. Is going.

[0015] The example shown in FIG. 6 is generated from a pulse using device such as a pulse flow transmitter in the device of the present invention. Pulse counter circuit (6) by inputting a pulse to the external pulse input circuit (4) Used to count the pulses input with and to use as a counter for pulse-using devices Is.

[0016]
