When an obvious fault occurs, please do not open it and repair it yourself, and contact us as soon as possible. 425 - 426 426 (2) In general, ORP electrodes do not need to be calibrated and can be used directly. When there is doubt about the quality and test results of the ORP electrode, the electrode potential can be checked with an ORP standard solution to determine whether the ORP electrode meets the measurement requirements, and the electrode can be recalibrated or replaced with a new ORP electrode. The frequency of calibration or inspection of the measuring electrode depends on different application conditions (the degree of dirt in the application, the deposition of chemical substances, etc.). 427 - 428 428 (3) There is an appropriate soaking solution in the protective bottle at the front end of the electrode, and the electrode head is soaked in it to ensure the activation of the platinum sheet and the liquid junction. When measuring, loosen the bottle cap, pull out the electrode, and rinse it with pure water before use. 429 - 430 430 (4) Preparation of electrode soaking solution: Take 25 grams of analytical pure potassium chloride and dissolve it in 100 ml of pure water to prepare a 3.3M potassium chloride solution. 431 - 432 432 (5) Before measuring, the bubbles in the electrode glass bulb should be shaken off, otherwise it will affect the measurement. When measuring, the electrode should be stirred in the measured solution and then placed still to accelerate the response. 433 - 434 434 (6) The electrode should be cleaned with deionized water before and after the measurement to ensure the measurement accuracy. 435 - 436 436 (7) After long-term use, the ORP electrode will be passivated, which is manifested as a decrease in sensitivity gradient, slow response, and inaccurate readings. At this time, the platinum sheet at the bottom of the electrode can be soaked in 0.1M dilute hydrochloric acid for 24 hours (0.1M dilute hydrochloric acid preparation: 9 ml of hydrochloric acid is diluted to 1000 ml with distilled water), and then soaked in 3.3M potassium chloride solution for 24 hours to restore its performance. 437 - 438 438 (8) Electrode contamination or liquid junction blockage can also cause electrode passivation. At this time, it should be cleaned with an appropriate solution according to the nature of the contaminant. If the platinum of the electrode is severely contaminated and an oxide film is formed, toothpaste can be applied to the platinum surface and then gently scrubbed to restore the platinum's luster. 439 - 440 440 (9) The equipment should be calibrated before each use. It is recommended to calibrate once every 3 months for long-term use. The calibration frequency should be adjusted appropriately according to different application conditions (degree of dirt in the application, deposition of chemical substances, etc.). After aging, the electrodes should be replaced in time. 441 441 442 442 == 3.6 RS485 Commands == ... ... @@ -459,6 +459,8 @@ 459 459 |=(% style="width: 50px;background-color:#4F81BD;color:white" %)New address|=(% style="width: 50px;background-color:#4F81BD;color:white" %)Function code|=(% style="width: 106px; background-color: rgb(79, 129, 189); color: white;" %)Data length|=(% style="width: 93px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 low|=(% style="width: 104px; background-color: rgb(79, 129, 189); color: white;" %)CRC16 high 460 460 |(% style="width:99px" %)0X01|(% style="width:112px" %)0X03|(% style="width:106px" %)0X00|(% style="width:93px" %)0X20|(% style="width:104px" %)0XF0 461 461 454 + 455 + 462 462 === 3.6.2 Change address === 463 463 464 464 For example: Change the address of the sensor with address 1 to 2, master → slave ... ... @@ -528,61 +528,13 @@ 528 528 0XC3 529 529 ))) 530 530 531 -= 4.
