 PERFORMANCE ORDER

Apply a digital or analog (arrow) tester to measurement of electric parameters – the voltmeter, an ohmmeter and other devices united in one case. At digital devices a small lag effect, they are insensitive to vibrations and position of the case at measurements, but arrow demonstrate dynamics of changes of the measured parameters. Besides the liquid-crystal display of digital devices is sensitive to lighting and temperature drops.
