I was hoping someone could help me with a problem with my D6 meter.
So I work at Fresenius and we are switching from the Phoenix XL over to the D6 meters.
I am having issues trying to complete the PH calibrations.
The 7.0 calibration works perfectly. When I finish the & and then add the 4 or 10 I keep getting a "FAC" code.
I cleaned the sensor with RO water, Placed rubbing alcohol in both sensor cells as per the manual to help clean the sensors. I have also changed out the ph sensor and reset the calibration back to factory settings.
I feel like I am doing something wrong during the calibration procedure. Can the D6 meter use the Mesa solutions or does it have to be Myron L solutions?
Outside of me doing the procedure wrong I am not sure what else to do.
These are brand new meters and I need to get my staff trained very soon.
Any help would be great.
Thanks..

This is from the manual
NOTE: Attempted calibration of >1 pH unit from factory calibration will
cause “FAC” to appear. This indicates the need for sensor replacement
(ref. Troubleshooting pg. 37-38) or fresh buffer solution.
Make sure you are only filling the pH sensor not the conductivity
The storage of the sensor with the correct solution is critical.
These pH sensors are finicky.

Also,
Maybe try a new bottle of solution just to make sure you have fresh solution........or didnt get a bad bottle.

I found the PH 4 and 10 was so far out of range it was showing the FAC code. I am thinking the staff may had gotten ahold of them before I did. When the FAC code came up I was so frustrated and started pushing the up and down arrows several times. Then about the time I was going to give up and call Myron L a number came up. Then I realized what the problem was. I have be able to get them all calibrated and ready to use.
Thank You for your help..

If you do need to change the cell, its PN: RPR in R2P/Ariba from myron l. usually set ya back about 95 bucks. not too hard to swap. you could try the super hot saltwater trick in the manual too on page 34 35 iv had pretty good luck that way.

You will love these meters compared to the phoenix meters.... really the only thing to change is the battery! For the most part they are bulletproof
