The MultiFiber Pro Meter is required to be calibrated annually. This should only be carried out at a Fluke Networks Authorized Service Center as they are the only ones that can adjust the instrument and reset the calibration date stored inside the instrument.
To view the current calibration on your MultiFiber Pro Meter, power on the meter then hold down the F1 and F3 keys for approximately 3 seconds. Then press the MENU/SELECT key eight times to see the calibration date. In the example below we see that the meter was calibrated on 20th June, 2012 (European format shown here). This calibration date is saved with the test result and can be viewed in LinkWare PC software.
