Important Safety Notice and Recall of the Amprobe ACD-10 PRO, ACD-10 TRMS-PRO, ACD-14 and ACD-14 TRMS Digital Clamp Meters June 25, 2007

In cooperation with the U.S. Consumer Product Safety Commission, Amprobe is voluntarily recalling the ACD-10 PRO, ACD-10 TRMS-PRO, ACD-14 and ACD-14 TRMS Digital Clamp Meters. Please stop using all of these products and return your unit to Amprobe and your unit will be replaced with either an ACD-14 PLUS, ACD-14 TRMS-PLUS, ACD-10 PLUS and ACD-10 TRMS-PLUS Digital Clamp Meter.

Description of the Problem 

The ACD-10 PRO, ACD-10 TRMS-PRO, ACD-14 and ACD-14 TRMS models “lock up” in certain circumstances failing to properly measure hazardous voltage levels on electrical systems. When the clamp meter locks up it provides readings under 1 volt or a millivolt reading. If the user does not follow industry standard practice by verifying the tester before and after checking a circuit, he/she may believe there is no voltage present when in fact there is. THIS COULD PLACE THE USER IN A POTENTIALLY HAZARDOUS SITUATION.

Requested Actions 

Stop using your ACD-10 PRO, ACD-10 TRMS-PRO, ACD-14 or ACD-14 TRMS Clamp Meter and contact Amprobe directly for a free replacement clamp meter. To request a replacement product, please call 1-800-350-8661 Monday through Friday between 7 a.m. and 4 p.m. Pacific Time.

As a replacement clamp, we offer either the ACD-14 PLUS, ACD-14 TRMS-PLUS, ACD-10 PLUS or ACD-10 TRMS-PLUS. The features of the replacement clamps are provided in the table below
