Voltage clamp readers recalled

Meters can give inaccurate readings

Posted May 30, 2017

The Consumer Product Safety Commission (CPSC) announced a recall of Extech digital clamp meters with model numbers EX650, EX655, MA160, MA61, and MA63. These models are all AC/DC clamp meters, which are electrical testing devices that measure voltage, resistance, capacitance, frequency, temperature, continuity, and diode.

According to the CPSC, 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.

Serial numbers in the following range are included in the recall: R15XXXXXXX to R17XXXXXXX.

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.

CPSC says anyone who has purchased one of these units should immediately stop using it and contact Extech for a free replacement meter.

The recall was conducted voluntarily by the company using the CSPC’s Fast Track Recall process. These recalls are initiated by companies who work with the CSPC to quickly announce a recall and protect the public.
