6.7 How to eliminate alarms
According to the alarm information prompt, adjust the alarm parameters to the normal range and the exclamation mark will automatically disappear. Replace the electrode and recalibrate.
After testing for a period of time, the pH of 6.8M420 suddenly became abnormal. After restarting, it returned to normal mainly due to an error in the wiring of the analog signal electrode. It is necessary to strictly follow the instructions for wiring Pay special attention to the annotations and explanations.
Difference in mouth model identification
For example: InPro4260SG/120/PT1000&InPro4260/120/PT1000.
So the mouth When wiring electrodes with SG function, connect the SG terminal to a blue cable: electrodes without SG function need to be short circuited to the reference and SG terminals.
During the calibration process, the electrode response is slow/sloping, and the zero offset is large. pH electrodes can age due to differences in production and usage environments (temperature, pH). If the electrode is calibrated multiple times with fresh buffer solution, this phenomenon indicates that the electrode's lifespan has expired.
Of course, the mouth. Improper operation can also cause this phenomenon. Check and avoid the following situations:
·Is the electrolyte inside the sensitive membrane full? If not, it needs to be vigorously shaken a few times to ensure that the electrolyte inside the sensitive membrane exceeds 1/2
·The electrode in the beaker should be suspended as much as possible
·The electrode sensitive membrane or diaphragm has attachments You can contact our company
