Installation and Wiring Steps
Correct installation is the prerequisite for ensuring measurement accuracy. Please follow the steps below.
- Fix the CA80PH transmitter on a stable, vibration-free bracket, avoiding direct sunlight.
- Connect the pH electrode, paying attention to grounding the cable shield to reduce electromagnetic interference.
- Connect the power supply (24 VDC or 220 VAC, depending on the model) and confirm the polarity is correct.
- Connect the output signal line to the PLC or recorder, and check the 4~20 mA loop.
- After power-on, observe the display. If the display is abnormal, refer to the fault code table in the manual.
Operation and Calibration Points
Daily Operation
- After power-on, wait 30 seconds until the reading stabilizes before recording.
- Regularly check whether the electrode is contaminated. If necessary, wipe it with a soft cloth dipped in cleaning solution.
- Avoid long-term exposure of the electrode to strong acid or strong alkali environments.
Calibration Process
It is recommended to perform two-point calibration every two weeks or after replacing the electrode.
- Prepare pH 4.00 and pH 7.00 standard buffer solutions.
- Immerse the electrode in pH 7.00 buffer solution, and confirm after the reading stabilizes.
- Clean the electrode, then immerse it in pH 4.00 buffer solution, and confirm after stabilization.
- After calibration, check that the slope should be between 95% and 105%.
Common Problems and Maintenance
The following lists common problems encountered by users and handling suggestions.
- Reading drift: Check whether the electrode is aged or the cable connector is damp.
- No display: Confirm the power supply voltage and fuse.
- Calibration failure: Replace the buffer solution or clean the electrode.
Regular maintenance can extend the service life of the CA80PH. It is recommended to replace the electrode filling solution once every quarter.
