Fluke has announced a user-downloadable firmware upgrade for the Fluke 8845A/8846A precision digital multimeters. The upgrade includes increased VDC reading rate to 1,000 readings per second, increased milliamp input range to 400 mA, and DCV:DCV ratio, enabling relative comparisons of two DC voltage test points. Added I DC and V DC dual measurement makes it easy to calculate power dissipation and simplifies battery power management testing in portable devices. The ability to create and store power-up instrumentation configuration means that once a meter has been configured, the set-up can be kept, even if the power is turned off or lost. In addition, the upgrade features model 8842A command emulation. Fluke Electronics Canada
