PWC100 Present Weather Sensor Calibrator
Step 5: Position 3: Right
• Move the calibrator into the right-hand position by unscrewing the
calibrator mounting screws slightly and sliding the calibrator fully to the
right. Then retighten the screws once in position.
• Visually check that the calibrator is located correctly and securely.
• LED R should now be flashing slowly and all other LEDs should be off.
• Once you are ready, press START.
• The test is now automated and the disk should start rotating. LED R will
stay illuminated until this stage of the test is complete.
• Wait for the calibration disk to stop rotating. This test will take
approximately two and a half minutes.
Final calibration results
The calibration verification has now been completed. All three of the LEDs
should be solidly illuminated indicating that the PWS100 is still within its
calibration limits.
If all three LEDs are flashing, then the calibration was found to be outside of
desired levels and further action needs to be taken.
If any of the calibration checks have failed (all three light flashing after test),
then the tests should be re-run after ensuring the disk is clean and the area
between the heads is clear of any obstructions. This should remove any chance
that the calibrator or another external factor was the cause.
If the PWC100 still indicates a problem, please contact Campbell Scientific for
further advice.
