1. Key definition 'ON/OFF' key: sensor power switch 'ENT' key: confirmation key '↑, ↓' key: up and down adjustment 2. Operation Description After the display is powered on, press the 'ON/OFF' key to supply power to the sensor , the screen displays the real-time residual chlorine value and temperature value at this moment, but the displayed value at this moment cannot be used as a reference value. After waiting for 1 minute, the residual chlorine and temperature changes in the water can be accurately displayed at that time. Menu setting instructions: 1 Enter the menu Press '↓' for 5 seconds when the machine is turned on normally, enter the parameter setting state, display 'str', press 'ENT' to confirm, and enter the residual chlorine zero point setting state. 2 Residual chlorine zero point setting The residual chlorine zero point setting can set and input the zero point value of residual chlorine from the beginning. Display 'CL1', press '↑' '↓' to change the parameters (range 2.40~2.60). Press 'ENT' to confirm and enter the setting status of residual chlorine slope. 3 Residual chlorine slope setting The residual chlorine slope setting can set the slope value of the input residual chlorine from the beginning. Display 'CL2', press '↑' '↓' to change the parameters (range 200~500). Press 'ENT' to confirm and enter the status of residual chlorine bias setting. 4 Chlorine bias setting (use with caution) The residual chlorine bias setting can change the residual chlorine value displayed at that time. After this calibration, the residual chlorine value of the output single point can be displayed more accurately. Display 'CL3', press '↑' '↓' to change the parameters (scale -0.30~+0.30PPM). Press 'ENT' to confirm and enter the state of temperature zero point setting. 5 Temperature zero point setting The temperature zero point setting can set the zero point value of the input temperature from the beginning. Display 't1', press '↑' '↓' to change the parameters (range 1.60 ~ 2.00). Press 'ENT' to confirm and enter the temperature slope setting state. 6 Temperature slope setting The temperature slope setting can set the slope value of the input temperature from the beginning. Display 't2', press '↑' '↓' to change the parameters (range 10.0~20.0). Press 'ENT' to confirm and enter the temperature bias setting state. 7 Temperature offset setting (use with caution) The temperature offset setting can change the displayed temperature value at that time. After this correction, the temperature value of a single point can be displayed more accurately. Display 't3', press '↑' '↓' to change the parameters (range -2.00~+2.00℃). Press 'ENT' to confirm and enter the pH value setting status. 8 PH Manual Compensation Setting The function of PH value setting is to input the PH value of the current solution into the meter as a calculation parameter, so that the residual chlorine value displayed and output by the meter is more accurate. PH default value is 7.5. 'PH' is displayed, press '↑' '↓' to change the parameters (range 6.0~9.0). Press 'ENT' to confirm and save the set parameters, and return to the normal display status.
