the screen.
The fourth procedure certifies the ICAM Selftest current measurement
circuitry, and the last certification screen is shown below.
Connect the ICAM Certification cable from the white connector on the ICAM
Selftest board to the Fluke 8840 Multimeter.
The ICAM IMON measurement certification tests the circuitry over six
different ranges with the results displayed to the right of the dialog. The result
of the current certification is also displayed. If any of these readings are out of
range, the small box adjacent to the result will appear red instead of green.
