Calibration Certificate for Greenlee/Tempo 501 Tracker II Cable Locator?

Below was received from the manufacturer:

“I can confirm that the 501 doesn’t ship calibrated nor is a calibration certificate available, but that’s only because the innerworkings are fortunately more simple compared to Tempo’s fiber products and the calibration isn’t necessary.”
