Standards, Options and Features


	Features
	Your choices are...
	Adjustable Sampling Rate		The sampling rate is manually adjustable.

	Data Storage / Logging		Data storage or data logging devices have internal memory for storing data.
	dB Readings		Devices measure values in decibels (dB).
	External Shunts		External shunts can be used to extend the current input range. For example, an input that exceeds 5 A can be measured by providing a shunt.
	Filters		Devices have embedded filters.
	Integrating Functions		Integrating functions allow the active power and current to be integrated (Wh and Ah).
	Mirrored Scale		Mirrored scales make it easier to read the instrument to a given accuracy by enabling the operator to avoid parallax errors.

	Standards and Certifications
	Your choices are...
	RoHS Compliant		Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS became effective on July 1, 2006.
	CE Marking		CE Marking indicates that a product complies with the essential requirements of relevant European Union (EU) directives that uphold national standards for health, safety and environmental protection. CE Marking is required in the countries of the European Economic Area (EEA), an organization that consists of the twenty five member states of the EU and the three members of the European Free Trade Association (EFTA). CE Marking refers to the safety of a product. It is not a quality standard.
	CSA Mark		Products that bear a CSA Mark have been tested by the Canadian Standards Association (CSA) and meet applicable standards for safety and/or performance. These standards are written and administered by organizations such as the American National Standards Institute (ANSI), Underwriters Laboratories (UL), and CSA International. CSA Marks may appear alone or with indicators. CSA Marks that appear alone are used with products certified primarily for the Canadian market, to the applicable Canadian standards. CSA Marks that appear with the indicators “C” and “US” or “NRTL/C” is used with products certified for both the U.S. and Canadian markets, to the applicable U.S. and Canadian standards.
	UL		Underwriters Laboratories (UL) is a non-profit organization that tests components, systems, and materials according to its published standards for safety. Products that receive UL approval bear a UL Mark.
	IEC 61010		The International Electrotechnical Commission (IEC) standards are an international organization that prepares and publishes International Standards for all electrical, electronic and related technologies. IEC 61010 standards are designed for protection against transient voltages. There are four categories: CAT I, CAT II, CAT III, and CAT IV. Within each category, there are standards based on the rated voltage (e.g., CAT III 1000 V, and CAT III 600 V). The EMC IEC standards rule on conformity assessment (certifications) to certify that equipment, systems or components conform to its International Standards. Most of the IEC standards on EMC are part of the IEC 61000 series of standards.
	WEEE Compliant		Waste Electrical and Electronics Equipment (WEEE) is a European Union (EU) directive designed to encourage the reuse, recycling and recovery of electrical and electronic equipment. WEEE is also designed to improve the environmental impact and performance of this equipment. The WEEE directive establishes requirements and criteria for the collection, treatment, recycling and recovery of electrical and electronic equipment. It also makes producers responsible for financing these activities. Retailers and distributors must provide a way for consumers to return used or obsolete equipment without charge.
