  • Page 38 1. While obtaining a process solution sample, record the pH value that is shown on the transmitter display. Emerson recommends taking the sample close to the sensor. 2. Measure and record the pH of the process solution sample with another temperature compensated, calibrated pH instrument.
  • Page 39 November 2020 Quick Start Guide Quinhydrone is only slightly soluble; therefore, use only a few crystals. 3. Immerse the sensor in the standard solution. Allow one to two minutes for the ORP sensor to stabilize. 4. Adjust the standardized control of the transmitter to the solution value shown in Table 3-1.
