Kyoritsu – KEW1009 1009 Auto-Ranging, Average-Sensing Digital Multimeter

The Kyoritsu 1009 digital multimeter (also known as a multitester) is an average-sensing, auto-ranging meter for measuring voltage, current, resistance, capacitance, frequency, and duty cycles in electrical testing applications. The meter comes with a set of detachable test leads. The meter measures duty cycles to 99.99%, indicating the percent of time a circuit is on. An audible continuity sensor confirms a circuit conducts electricity, and a diode test detects proper functioning of a circuit’s diodes. The LCD can display the present measurement value or the highest or lowest measurement value for a session. It shows readings in digits and on a bar graph. The relative mode stores a reading in memory to use as a zero point for subsequent readings so that multiple readings can be compared. The hold function keeps a reading on the LCD, even after the meter is disconnected. The unit automatically turns off after 30 minutes of nonuse to conserve battery life, and a low-battery indicator signals when the meter’s batteries need to be replaced. A removable rubber holster helps protect the meter during transport and storage.

Multitesters (also called multimeters) are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multitesters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multitesters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltages. Safety ratings are based on the International Electrotechnical Commission’s (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.


Kyoritsu manufactures electrical testing and measurement instruments such as multimeters, clamp meters, and power quality analyzers. The company, founded in 1940, is headquartered in Tokyo, Japan.
