We can use a Wheatstone bridge voltage measurement to determine an unknown resistance value. In part 3 of this series, we used Kirchhoff’s voltage law to derive the branch currents and node voltages for an unbalanced Wheatstone bridge with five known, fixed resistors (Figure 1). Now, we propose to replace R5 with a digital multimeter […]

Tryout: two low-cost USB inline meters and a load
Despite their limited use for testing wall chargers and power banks, USB inline testers let you compare power sources. In three videos, we take you through their features, and we also try an inline USB electronic load. When testing a USB charger or power bank, you can connect a phone or other device and see […]
Digital Multimeter Has USB & Cable Adapters
Fluke Corporation announced enhancements to its bench digital multimeters. The Fluke 8808A 5.5 digit Digital Multimeter and the 8845A/8846A 6.5 digit Multimeters will now include a USB to RS232 Cable Adapter as well as FlukeView Forms Basic software. www.fluke.com
Multimeter Works Two Places at Once
For the first time, a multimeter will allow electricians and electronic technicians to work in two places at once, says Fluke Corp., provider of portable electronic test and measurement technology. Fluke introduced what it calls the industry’s first digital multimeter with a detachable wireless display. Designed by Fluke engineers and manufactured at the Fluke Worldwide […]
