Power Meter - VFL Software ICON is missing from MAX Optical tester desktop / homescreen on boot up.


Troubleshooting steps

‚ÄčPossible Cause 1: Your unit is not configured with the optional PM/VFL mini-module.

Proposed Solution:

  • The application icon will only be present if a mini-module is installed. If there is no PM/VFL mini-module, it is normal that the application icon is not displayed.


Possible Cause 2: The PM/VFL mini-module is incorrectly seated in the unit.

Proposed Solution:

  • Reseat the PM/VFL module in the unit.
  • Press and hold the On/Off button a few seconds until the unit beeps once to put it in shutdown mode.
  • Disconnect the unit from its external power source.
  • Put on a wrist (or an ankle) antistatic strap and ensure that it is grounded properly.
  • Place the unit vertically so that its front panel (display) is facing you.
  • On the top panel of the unit, locate the PM/VFL.
