Dear @nesrinealhourani, It depends on what the notification is exactly. For example, if the standard temperature is out of range then temperature has to be defined by creating a customized standard group with the required temperature range. If slope is out of range, then clean the sensor with appropriate cleaning reagents and try reconditioning in dilute HCl solution for over 12 hours. If offset is out of range then check for junction blockage and clean with the appropriate reagent. For a thorough troubleshooting, kindly contact our pH competence and support center at pH.Lab.support@mt.com.
