ELECTRONICS: Equipped with capabilities found in more expensive instruments of this type, the new 0.1 percent Accuracy, Bench Model, LCR Meter from Protek Test and Measurement features RS 232 and Handler interfaces. For its $992 price tag, the Model Z8900 offers six measurement modes including C+R, C+D, L+R, L+Q, R+Q or Z+È at test frequencies of 100 Hz, 120 Hz, 1 KHz or 10 KHz, with drive voltages of 0.1V, 0.3V, or 1.0V and measurements rates to 12 per second. It incorporates a built-in comparator for sorting components according to value and tolerance, a RS232 interface for Remote operation and a Parts Handler Interface for operating your component sorting equipment. Add to these, a large five-digit dual LCD for displaying parameter values in Absolute, Delta and Delta %, Automatic or Manual triggering; and short and open circuit calibration for increasing measurement accuracy. Accessories include: operating manual, test leads with Kelvin clips; radial lead test fixture with axial lead adaptor; shorting bar; and AC line cord. The Z8900 requires 220V or 120, 50/60 Hz ac power, switch selectable and operates in temperatures from 0 to 40C (32 to 104F). Weight is 7.7 lb and size is 13 inches wide x 6 inches high x 15.7 inches deep.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
