Мультиметр схема m812


This circuit was designed for a sound effect, but may serve other useful purposes when a basic, swept-frequency audio source is required. Appropriate component-value substitutions will yield variations in these parameters. Among the essentials for circuit design and prototyping is the continuity tester, a simple device which provides an audible indication when a sufficiently low resistance is applied between its input probes.

It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. Although originally designed for application in a communications system, the idea is readily adaptable for certain electronic music applications where waveform conversion is desired.

Мультиметр схема m812

It detects if there is another telephone connected to the line, if there is a short or an open line. It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. Although originally designed for application in a communications system, the idea is readily adaptable for certain electronic music applications where waveform conversion is desired.

This version has a feature which automatically turns off the tester after about two minutes, thereby saving the 9 volt battery from inadvertent discharge. Among the essentials for circuit design and prototyping is the continuity tester, a simple device which provides an audible indication when a sufficiently low resistance is applied between its input probes.

Мультиметр схема m812

If you feel that somebody is tampering with your telephone line you might find this little circuit useful. It produces both square and triangular wave outputs that ascend from about 80 to Hertz in a repeating cycle of about 12 seconds. This is a rather sensitive circuit which will detect minute variations of a magnetic field, particularly the Earth magnetic field.
