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.
