RM3 SERIES BACKREFLECTION METER

USER’S MANUAL

Getting Started

The RM3 Series Backreflection Meter consists of the meter, an AC power cord, two jumpers, and a foot pedal.

Before Initializing and Operating the Unit

Inspect the unit for any signs of damage.

Read the user’s manual thoroughly, and become familiar with all safety symbols and

￿instructions to ensure that the unit is operated and maintained safely.

If the unit is used in a manner not specified by JDS Uniphase, the protection provided by the unit may be impaired.

Initial Inspection

Warning

To avoid electrical shock, do not initialize or operate the unit if it bears any sign of damage to any portion of its exterior surface, such as the outer cover or panels.

Check that the unit and contents are complete:

1.Inspect the shipping container for any indication of excessive shock to the contents, and inspect the contents to ensure that the shipment is complete.

2.Inspect the unit for structural damage that can have occurred during shipping.

3.Connect the unit to the power source using the power cord provided.

4.Set the power switch to ON to initialize the RM meter, and observe the power-up sequence. The model number of the meter is displayed. Internal measurements of P in and Pdark are made. The message “Stabilizing” is displayed as the light source stabilizes. The backreflection value (BR) of the front panel connector is measured and displayed.

5.Set the power switch to OFF and disconnect the RM meter.

6.Connect the foot pedal to the Log port at the back of the meter if you intend to send data from the meter to a computer or printer.

7.Keep the packaging.

Immediately inform JDS Uniphase and, if necessary, the carrier if the contents of the shipment are incomplete, if the unit or any of its components are damaged or defective, or if the unit does not pass the initial inspection.
