Q - When do I need to change my calibration card?
A - The expiration date of the Density Calibration Reference is printed on the card. The Density Calibration Reference has to be replaced after the expiration date.
Always keep your density calibration reference in its protective cover in a dry place. Do not soil or scratch the calibration elements. Clean the density calibration reference with a soft cloth only.
