Hey all... picked up a Apogee Quantum SQ-420 PAR meter the other day... the standard software download reflects light intensity in micromoles, so I have to manually multiply my readings by 2.1 and I have no idea how to reconfigure the software... I wrote to the Apogee "help desk" 5-6 weeks ago and am still awaiting a response... I am SURE that someone else out there has had this same issue and can assist me - miss you guys (and gals)...
Happy reefing, many thanks and stay safe "eh" ;o)
