Production Line High-Speed Resistance Meter for
Greater Precision in Resistor Devices
Mobile computers, cellular phones and consumer electronics products are being made in smaller and smaller
sizes and with more advanced features. The resistor
devices used in these products also need to be smaller
and more precise, while pricing is becoming more of an
issue. At the same time, ISO9000 and other standards
have made the maintenance of measurement instruments more important, and the globalization trend is leading companies to move more of their device production
facilities offshore. The 7556 Series of digital resistance
meter was developed in light of these issues to meet the
new requirements for resistor device production lines.
