Page 11: General Information
This section provides general instructions on how to use the XL fiberTOOLS instruments. If circumstances require that the instruments be serviced and main- tained in-house, contact Greenlee for technical assistance. Battery Installation or Replacement All XL fiberTOOLS instruments are powered by two AA-size 1.5 volt alkaline batteries. - Page 12 Battery Installation or Replacement (cont’d) To replace the batteries, follow these steps: 1. Carefully remove the protective rubber cover. 2. Turn the instrument onto its front face, then open the battery com- partment by pressing on the center of the cover (Step 1 below) while pulling on the sides (Step 2 below).

This is indicated by the “r” annunciator appearing in the lower right-hand corner of the LCD screen. Note: The 560XL Series optical power meters incorporate multi- wavelength reference storage capability. This enables a 0 dB reference value to be stored in non-volatile memory for each calibrated wave- length. -
Page 18: Setting The Source Modulation Frequency
ALWAYS BE SET TO THE “OP” POSITION. TAMPERING WITH THE CAL/OP SWITCH WILL VOID CALIBRATION OF THE INSTRUMENT. Input interface: This is the optical input connector. All 560XL Series optical power meters are equipped with a SOC interface. Setting the Source Modulation Frequency All 570XL Series LED sources and 580XL Series laser sources are shipped with the modulation frequency switch set at 1 kHz. -

(Method B), and OFSTP-14 (Method B). 1. Connect an appropriate light source to the optical power meter using a suitable reference cable with a length of about 2 to 3 meters (6 to 10 feet), as shown below. 560XL • 570XL • 580XL... - Page 20 One Test Jumper Method: Connector Loss (cont’d) 2. Ensure that the light source is in continuous wave (CW) output mode. Set the optical power meter to the appropriate wavelength (using the [λ] key) and to dBm units (using the [dB/dBm] key). Note that the dBm output of the reference cable should be within acceptable limits.
