PhotoExtech of Goleta, Calif., is recalling about 1,720 digital clamp meters sold in the U.S. and Canada.

The meters can fail to give an accurate voltage reading, resulting in the operator falsely believing the electrical power is low or off, posing an electrocution hazard.

The company has received two reports of clamp meters displaying an incorrect voltage reading. No injuries have been reported.

This recall involves Extech digital clamp meters with model numbers EX650, EX655, MA160, MA61, and MA63 in the colors of green and orange.

These models are all AC/DC clamp meters, which are electrical testing devices that measure AC/DC voltage, resistance, capacitance, frequency, temperature, continuity, and diode.

Serial numbers in the following format are included in the recall: R15XXXXXXX to R17XXXXXXX. Only serial numbers in this range are included in the recall.

The “EXTECH” logo and the model number are printed on the front of the unit and the serial number on the back.

The clamp meters, manufactured in China, were sold at Grainger, Platt Electric Supply stores and industrial and electrical distributors and wholesalers nationwide and online at and other websites from January 2016, through April 2017, for between $110 and $230.
