    PH module for Jr help!

    Well I plugged in the PH module and calibrated the probe, but on fusion it comes up with some wild number like 7.04. An the display says PH x2....... WTF?

    How to I start over and get rid of PHx2?

    You can rename it in the classic dashboard to whatever you want. The x2 is the default designation to differentiate it based ON aquabus number so a system that already has a pH probe can't get two of the same name.

    Do a manual calibration several times until the settling values are near 700 and 1000 respectively.

    Apex Jr. PM1 module questions

    Hi All,
    I just hooked up my PM1 to Apex jr.:
    Is there a way to see/configure the module on Fusion besides just seeing the PH read out?
    Is there a way to update firmware for PM1 module from Fusion?
    The lab probe will not settle for cal. any lower than 725 and 1035 respectively. It read lower PH in the tank than I think it really is. It read 7.74,
    but I'm pretty sure it's more like 8.0/8.1

    Thanks in advance!

    Check it again in the calibration solutions and make sure it reads 7.00 in 7.01 and 10.0 in 10.01 solutions. If not, run it one more time and you should be good to go

    What Zombie is suggesting is to check your calibration.

    AFTER you calibrate, put the probe back into the solutions. If it reads 7 in the 7 and 10 in the 10, then the probe is calibrated and your tank is indeed at 7.74
