Calibration of BH 485 PH Digital Online pH Sensor BOQU instrument

Calibration condition: 1.Digital pH sensor is directly with Standard RS485 Modbus. 2.Calibration buffer:pH value:4.01,7.00 and 10.01 3.Distilled water is to clean pH sensor in each step. 4. Calibration software is Modbus poll on computer. 5. The Address is 2. Calibration steps. 1.First point is to calibration pH 7, put pH sensor in buffer 7;then send value 1 in register 13. 2.After measured value stable, then change pH sensor to another buffer 4.01 or 10.01.(clean pH sensor by distilled water when change buffer) 3.Then send value 2 in register 13 to start Second point calibration. 4.The pH sensor is pass test when slope over 95.(the slope value is in register 15) Calibration finished Note: 1)Register 6 is to choose pH or ORP(0 is for pH,1 is for ORP),the default is 0 for pH when delivery. Register 4 is to choose right temperature compensation,the default is 30K(“0” is for 30K, “1” is for 10K,“2” is for PT1000,“3” is for 2.252K You are welcome to visit our website for more more information: www.boquinstrument.com Email: Phoebe@shboqu.com Whatsapp:+86 158 7237 6841
