Jonard Tools, as one might suspect, offers a diverse array of both passive hand tools, powered tools, and measurement tools such as their FPM-55 optical power meter. Useful for diagnosing optical networks and systems, this meter is an electronic tool and thus we routinely receive questions concerning calibration and whether it comes supplied with proof of calibration. Does this ship with a calibration document?
Per the supplier’s web page, the product comes pre-calibrated from the factory but does not include any specific calibration documentation. Requests for specific documentation would need to be directed to Jonard directly, as the manufacturer of the device.
