May 29, 2017 - FLIR Commercial Systems Inc. is recalling certain models of Extech digital clamp meters that may fail to give an accurate voltage reading, resulting in the operator falsely believing the electrical power is low or off, posing an electrocution hazard.

This recall stems from consumer reports that the clamp meter’s input terminal screws are loosening, says Extech. The loosened screws can create an open circuit at the test lead input jack of the meter, causing the meters to give inaccurate voltage readings.

These AC/DC digital clamp meters are used to measure AC/DC voltage, resistance, capacitance, frequency, temperature, continuity and diode.

The recall involves Extech digital clamp meters with model numbers EX650, EX655, MA160, MA61 and MA63. Serial numbers in the following format are included in the recall:


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 digital clamp meters are green and orange.

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

According to Health Canada and the U.S. CPSC, about 21 units of the affected products were sold in Canada, and about 800 in the States. The units were manufactured in China.

Consumers should not return the recalled clamp meters to the retailer where they were purchased, as retailers are not prepared to take the units back. Instead, you should immediately stop using the recalled clamp meters and complete Extech’s Recall Submission Form, email This e-mail address is being protected from spambots.
