PERANCANGAN ALAT UKUR SUMBER AC/DC SECARA OTOMATIS

Abstract

Abstract
Automatic control of the measurement system is the feedback control system
with a reference input or output in the desired change can be constant or slowly over
time. Advances in science and technology over time evolving rapidly, especially in the
field of automatic control, which previously were using the manual. Then it must have a
very noticeable flaws both in terms of measurement or in terms of reading the value that
has been measured. With the rapid advancement of mobile digital era as it is today,
especially in the field of automated technology, the disadvantages are that there should
be minimized. So in this study designed a source measure AC / DC automatically to
anticipate that no error occurs when the measure. In addition, automatic measuring
instrument is supported by advances in technology which uses ATmega328P-PU
microcontroller, ACS712 current sensor-05B, AD736, LM7805, LM7815, LM7915, 16x2
LCD and other components. Tests using the gauge source AC / DC has been designed
automatically generate more digital measurement results compared with the manual
gauge readings using scala. Here is the percentage of fault of each parameter were
tested, namely: Percentage frequency error of 5.15% auto gauges, voltage error
percentage 1.67% automatic gauges, flow gauges percentage error of 3.64% automated.
