Configuration Menu > CCR Config > Calibrate > Output Current
□ The LOCAL UP and LOCAL DOWN arrows will still operate while in the menu, allowing for
easier calibration. Put the CCR on the lowest brightness step.
□ Once the CCR is on the lowest brightness step, push the left DOT button to enter the
“Output Current” screen.
□ Check the DMM-measured current value. Use the UP and DOWN arrows below the screen
to adjust the calibration value. Once the values match, push the left DOT button to accept.
□ Put the CCR on the highest brightness step, while staying in the calibration menu.
□ Check the DMM-measured current value. Use the UP and DOWN arrows below the screen
to adjust the calibration value. Once the values match, push the left DOT button to accept.
□ Cycle through the brightness steps, and verify the new calibration with the DMM. If the
calibration is now acceptable, push the right D OT button until you’re asked to Record
Changes, to which you need to execute Yes.
□ If the calibration needs additional fine-tuning, complete the calibration procedure again.
□ If the calibration procedure does not yield acceptable results, you may want to restore a
known good calibration. Refer to Section 7.2.2 Restoring a Known Good Calibration for
more information.
7.3.3 Calibrating Output Voltage
Before continuing, refer to Section 7.3.1 How to Determine if Recalibration is Needed . If it is
determined that recalibration is required, complete the following steps fully to ensure the most
accurate results. Read all steps before beginning. Contact Airport Lighting Company for additional
information as needed.
Note: a resistor load bank, such as can be provided by Airport Lighting Company, is recommended
to provide a purely-resistive load to the CCR during calibration. Ideally, the CCR should be loaded
at 100% of its kW rating for the most accurate calibration.
□ Before doing a full recalibration, complete a “Calibrate Zeros” of the CCR. Refer to Section
5.1.2 Calibrate Zeros . Once the Calibrate Zeros is done, check to see if the reading
discrepancy still exists. If it does, continue.
□ Connect a load bank to the CCR.
