Installing or Removing the Power Meter and VFL
12. Remove your antistatic strap.
13. Connect your unit to an external power source if desired.
14. If it is not already done, turn on your unit.
15. Start the power meter application to ensure that the instrument is
working properly.
Note: If the power meter is not detected, this could mean that it is not inserted
properly in the unit. In this case, repeat the installation procedure. If the
problem persists, contact EXFO.
To remove the power meter for recalibration:
1. Press and hold the On/Off button a few seconds until the unit beeps
once to put it in shutdown mode.
2. Disconnect the unit from its external power source.
3. Put on a wrist (or an ankle) antistatic strap and ensure that the end of
its wire is grounded properly.
4. Place the unit vertically so that its front panel is facing you.
