Introduction Congratulations on your purchase of the Extech PQ2071 1/3-Phase CAT IV True RMS 1000A Power Clamp Meter. The PQ2071 measures AC Current, Frequency, Temperature (Type K), and Power (True Power, Apparent Power, Reactive Power, and Active Power). The PQ2071 also includes a built-in non-contact Voltage Detector with LED alert. - Page 3 Turn the Meter off when it is not in use and remove the battery when the meter is to be stored or unused for long periods. Keep track of the battery age and replace batteries when necessary. Leaking batteries can damage the meter. PQ2071-en-GB_V1.3 7/15 contact: www.ponpe.com sale@ponpe.com...
