a) Red line - power cord (12 ~ 24 V DC)
b) Black line - ground (GND)
c) Blue line - 485 A
d) White line - 485 B
e) Bare wire - shielded wire
After wiring is completed, it should be carefully checked to avoid incorrect connections before powering up.
Cable specification: Considering that the cable is immersed in water (including sea water) for a long time or exposed to the air, the cable has certain corrosion resistance. The outer diameter of the cable is Φ6 mm and all interfaces are waterproof.
The fluoride ion electrode was activated in deionized water for 24 hours prior to use.
The sensing element of the fluoride ion electrode must be cleaned with deionized water and kept dry during storage. If the storage time is more than 8 hours, put a protective cap on the film head. The reference solution of the composite electrode is careful not to be evaporated to cause crystallization. Prior to testing, if the electrode storage time is less than one week, 50 mL of TISAB can be soaked in 50 mL of deionized water. If the storage time is more than one week, the electrode should be cleaned, wiped dry, and placed in the original packaging.
Check if the terminal is dry. If it is stained, wipe it with absolute alcohol and dry it. Avoid long-term immersion in distilled water or protein solution and prevent contact with silicone grease. The electrode is used for a long time. When a measurement error occurs, it must be calibrated with the meter.
When the calibration and measurement cannot be performed while maintaining and maintaining the electrode in the above manner, the electrode has failed. Please replace the electrode.
Note: The sensor has been calibrated before leaving the factory. If it is not beyond the measurement error, it should not be arbitrarily calibrated.
a) Zero calibration
Place the sensor in a vial containing the zero standard solution and wait for 5 minutes. After the value is stable, see if the displayed value is within the error range. If not, perform a zero calibration. Refer to the appendix for calibration instructions.
b) Slope calibration
Place the sensor in a vial containing the standard solution of the slope and wait for 5 minutes. After the value is stable, see if the displayed value is within the error range. If not, the slope calibration is required. Refer to the appendix for calibration instructions.
