USER’S MANUAL

3.Press the λ key to select the wavelength at which the calibration check is to be performed. Choose either wavelength, as you will check both.

4.Measure the power from the output of the calibrated jumper, using a high-accuracy, calibrated power meter.

5.Clean the output connector of the calibrated jumper, and connect it to the detector on the front panel of the RM meter. The value displayed on the RM meter must match the value measured by the power meter to within ±0.3 dBm.

If the values do not match to within ±0.3 dBm, adjust the value of User CAL:

1.Use a screwdriver or an appropriately narrow object to press CAL. The last User CAL value stored is displayed on the meter.

2.Press and hold the Store ID key to scroll to the required value in 0.01 dBm increments.

3.Press the CAL key to store the User CAL value, and return the meter to the power measurement display.

4.Repeat the calibration adjustment procedure (steps 1 to 3) for the second wavelength.

Maintaining the Meter

Caution

Devices with malfunctioning lasers must be returned to the manufacturer for repair.

Cleaning the Unit

1.Unplug the unit from the line power.

2.Clean the enclosure with a damp cloth.

3.DO NOT plug the unit back until it is completely dry.

Cleaning the Connector Ends

Clean all connector ends with a lint-free tissue and alcohol before every mating. See the Cleaning Connectors section.

1.Loosen the retaining screws of the connector panel, and remove the panel carefully to access the internal connectors (Figure 10).
