Installing or Removing the Power Meter and VFL
Installing or Removing the Power Meter and
VFL
If your unit was not equipped with a power meter (or a power meter and a
VFL) at time of your initial purchase, you can purchase one afterwards and
install it yourself.
You may also need to remove the power meter to send it to an authorized
service center for recalibration.
Note: If you prefer not to remove the power meter from your unit when a
calibration is needed, you can also send the complete unit to the service
center.
Note: The illustrations presented hereafter show a power meter and a VFL. The
appearance of your test instrument may vary slightly depending on the
model that you have purchased.


To avoid serious injuries as well as irreparable damages both to
your unit and your power meter, ALWAYS TURN OFF YOUR UNIT
(shutdown mode, not suspend) and DISCONNECT IT FROM THE
EXTERNAL POWER SOURCE. For more information on the ways
to turn off your unit, see Turning On or Off the Unit on page 21.

Always use caution during the installation or removal process.
Even if the unit is disconnected from its external power source,
the battery continues to provide power to certain areas of the
unit.

Be careful not to drop metal objects such as screws inside the
unit. These could cause a short-circuit leading to a fire or an
explosion.
