Installing or Removing the Power Meter and VFL

To install a power meter:

1. Turn off your unit.

2. Disconnect the unit from its external power source and remove the

batteries.

3. Put on a wrist (or an ankle) antistatic strap and ensure that the end of

its wire is grounded properly.

CAUTION

Electrostatic discharge (ESD) damage can cause complete or

intermittent equipment failures.

 Always use an ESD-preventive wrist or ankle strap when

handling the power meter. Ensure that the antistatic strap

makes good skin contact and that the end of its wire is

grounded properly.

 Always handle the power meter by the edges of its metal

faceplate (where the detector port is located).

 Never touch the circuit board.

 Keep any piece of clothing away from the power meter during

the handling.

 Never touch any component inside the unit either with tools or

your fingers.

 Only place the power meter on antistatic surfaces such as an

antistatic mat, and quickly put power meters that need

recalibration into antistatic bags.

CAUTION

Use only power meters and VFL designed for your unit and

approved by EXFO.
