Abstract

The development of technology in the industrial,
marine, offshore and onshore fields is growing rapidly, including
from high and low voltage electrical equipment which increasingly
varies from voltage, current, inductance, capacitance, resistance,
frequency and power factor. Therefore a multimeter is made which is
very useful for measuring the quantities found in industrial and
household electrical equipment. However, there are several problems
encountered when measuring using a multimeter, such as difficulty in
reading an unknown value because the measuring instrument has an
upper or lower limit. Therefore, in this study, a tool that can measure
electrical equipment with many variations of measurement is used
and can be monitored from a safe distance through the Blynk android
application found on a smartphone. Based on the tests that have been
done, this tool is able to perform its function properly with an
accuracy rate of 89,5% of current, 89,1% of voltage, 98% of
frequency, 96% of power factor, 86% of resistance, 86,9% of
capacitance and 87,8% of inductance.
