When an obvious fault occurs, please do not open it and repair it yourself, and contact us as soon as possible. 435 - 436 436 (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.). 437 - 438 438 (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. 439 - 440 440 (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. 441 - 442 442 (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. 443 - 444 444 (6) The electrode should be cleaned with deionized water before and after the measurement to ensure the measurement accuracy. 445 - 446 446 (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. 447 - 448 448 (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. 449 - 450 450 (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. 451 451 452 452 == 3.6 RS485 Commands == ... ... @@ -455,7 +455,7 @@ 455 455 RS485 signaldefault address 0x13 456 456 Standard Modbus-RTU protocol, baud rate: 9600; check bit: none; data bit: 8; stop bit: 1 457 457 458 -=== 3.6.1 Query address===440 +=== 3.6.1 Query data === 459 459 460 460 send 461 461 ... ... @@ -469,6 +469,8 @@ 469 469 |=(% 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 470 470 |(% style="width:99px" %)0X01|(% style="width:112px" %)0X03|(% style="width:106px" %)0X00|(% style="width:93px" %)0X20|(% style="width:104px" %)0XF0 471 471 454 + 455 + 472 472 === 3.6.2 Change address === 473 473 474 474 For example: Change the address of the sensor with address 1 to 2, master → slave ... ... @@ -538,173 +538,27 @@ 538 538 0XC3 539 539 ))) 540 540 541 -= 4.
