Hewlett-Packard (www.hewlett-packard.com) has published a booklet entitled, 10 Practical Tips You Need to Know about Your Power Products, designed to provide engineers with hints for enhancing power-product operation and using measurement capabilities. Areas covered include: using remote sensing to compensate for load-lead effects; charging/discharging batteries; using remote inhibit and discreet fault indicator; eliminating noise from low-level measurements; using constant-current load with foldback power supplies; getting higher voltages and currents by connecting power supplies in series or in parallel; making pulsed- and dynamic-current measurements with a power supply; and characterizing ac in-rush current.
