Fluke 190 ScopeMeter® Recall

Dear Fluke Customer:

Fluke is voluntarily recalling its 190 Series ScopeMeter®100MHz and 200MHz 4 Channel Hand Held Oscilloscopes that contain firmware version V10.40. This includes all units manufactured between February 5, 2012 and April 3rd 2012 and have a serial number range of 1954xxxx to 2009xxxx, and all units upgraded to firmware version V10.40 after February 5, 2012.

Description of the problem

Four channel models with the latest firmware (V10.40) may display the decimal point of the measurement value in the wrong position. This poses a potential safety risk for the user, as an unsafe voltage may be indicated as a much lower (safe) voltage. THIS RISK COULD RESULT IN SERIOUS INJURY OR DEATH.

The affected models numbers are listed in the table below. You can determine whether your 4-channel ScopeMeter® is being recalled by checking the firmware version as described below. Stop using it until after that determination is made.
