As Cortland alluded to on this thread, I have gotten consulting work when equipments were falsely failed during susceptibility testing due to using a DMM to monitor a pass/fail criterion, and the DMM acted as an rf detector and indicated a false reading. Using a permanent magnet / d'Arsonval movement meter rectified (!) the situation.
I have many such meters in nice wood and bakelite boxes in my facility, and use them regularly to eliminate (no - reduce) the chances of doing something stupid.
