MODEL SOLU COMP II SECTION 6.0 CALIBRATION 6.2 CALIBRATING TEMPERATURE 6.2.1 Purpose Temperature is important in the measurement of pH, ORP, and conductivity (or resistivity) for different reasons. Temperature affects the measurement of pH in three ways. 1. The analyzer uses a temperature dependent factor to convert measured cell voltage to pH. Normally, a slight inaccuracy in the temperature reading is unimportant unless the pH reading is significantly different from 7.00. Even then, the error is small.
PAGE 56
MODEL SOLU COMP II SECTION 6.0 CALIBRATION 6.2.2 Procedure 1. Remove the sensor from the process. Place it in an insulated container of water along with a calibrated thermometer. Submerge at least the bottom two inches of the sensor. Stir continuously. 2. Allow the sensor to reach thermal equilibrium. For some sensors, the time constant for a change in temperature is 5 min., so it may take as long as 30 min. for temperature equilibration. 3.
PAGE 57
MODEL SOLU COMP II SECTION 6.0 CALIBRATION 6.3 AUTO CALIBRATION — pH 6.3.1 Purpose 1. New sensors must be calibrated before use. Regular recalibration is also necessary. 2. Use auto calibration instead of manual calibration. Auto calibration avoids common pitfalls and reduces errors. 6.3.2 Definitions 1. AUTO CALIBRATION. The analyzer recognizes the buffers and uses temperature-corrected pH values in the calibration. The table lists the buffers the Solu Comp II recognizes.

Use manual calibration if non-standard buffers are being used; otherwise, use auto calibration. Auto calibration avoids common pitfalls and reduces errors. 6.4.2 Definitions 1. MANUAL CALIBRATION. In auto calibration the analyzer recognizes the buffer and uses the temperature-corrected pH value in the calibration.

MODEL SOLU COMP II SECTION 6.0 CALIBRATION 6.5 STANDARDIZATION — pH 6.5.1 Purpose 1. The pH measured by the Solu Comp II analyzer can be changed to match the reading from a second or referee instrument. The process of making the two readings agree is called standardization. 2. During standardization, the difference between the two pH values is converted to the equivalent voltage. The voltage, called the reference offset, is added to all subsequent measured cell voltages before they are converted to pH.
PAGE 62
MODEL SOLU COMP II SECTION 6.0 CALIBRATION 6.6 ENTERING A KNOWN SLOPE VALUE — pH 6.6.1 Purpose If the electrode slope is known from other measurements, it can be entered directly in the Solu Comp II analyzer. The slope must be entered as the slope at 25°C. To calculate the slope at 25°C from the slope at temperature t°C, use the equation: 298 slope at 25°C = (slope at t°C) t°C + 273 Changing the slope overrides the slope determined from the previous buffer calibration. 6.6.
PAGE 63
MODEL SOLU COMP II SECTION 6.0 CALIBRATION 6.7 ORP CALIBRATION 6.7.1 Purpose 1. For process control, it is often important to make the measured ORP agree with the ORP of a standard solution. 2. During calibration, the measured ORP is made equal to the ORP of a standard solution at a single point. 6.7.2 Preparation of ORP standard solutions ASTM D1498-93 gives procedures for the preparation of iron (II) - iron (III) and quinhydrone ORP standards. The iron (II) - iron (III) standard is recommended.

MODEL SOLU COMP II SECTION 6.0 CALIBRATION 6.8 CALIBRATING AN IN-SERVICE SENSOR — CONDUCTIVITY 6.8.1 Purpose 1. After a conductivity sensor has been in service for a period of time, recalibration may be necessary. 2. There are three ways to calibrate a sensor. a. Use a standard instrument and sensor to measure the conductivity of the process stream. It is not necessary to remove the sensor from the process piping. See Figure 6-2.

MODEL SOLU COMP II SECTION 8.0 TROUBLESHOOTING 8.2.2 pH Sensitive Glass Membrane is Broken The Solu Comp II continuously measures the impedance between the sensor solution ground and the inside of the pH-sensing electrode. If the glass membrane is intact, the impedance is normally between 10 MΩ and 1000 MΩ. If the membrane is cracked or broken, the impedance drops below 10 MΩ. If the membrane is cracked or broken, the sensor must be replaced. 8.2.

MODEL SOLU COMP II SECTION 8.0 TROUBLESHOOTING 8.3.7 Calibration Was Successful, but Process pH Is Grossly Wrong and/or Noisy. Grossly wrong or noisy readings suggest a ground loop (measurement system connected to earth ground at more than one point), a floating system (no earth ground), or noise being brought into the analyzer by the sensor cable. The problem arises from the process or installation. It is not a fault of the analyzer.

MODEL SOLU COMP II SECTION 8.0 TROUBLESHOOTING 8.6 SIMULATING INPUTS — pH 8.6.1 General This section describes how to simulate a pH input into the Solu Comp analyzer. To simulate a pH measurement, connect a standard millivolt source to the transmitter. If the transmitter is working properly, it will accurately measure the input voltage and convert it to pH. Although the general procedure is the same, the wiring details depend on the location of the preamplifier. 8.6.

MODEL SOLU COMP II SECTION 8.0 TROUBLESHOOTING 8.7 SIMULATING INPUTS — CONDUCTIVITY To check the performance of the analyzer, use standard resistors to simulate conductivity. A. Set the temperature correction to raw (Section 5.5). B. Connect the standard resistors to TB-5 as shown in Figure 8-4. C. Determine how closely the displayed resistivity or conductivity agrees with the known resistance.

MODEL SOLU COMP II SECTION 8.0 TROUBLESHOOTING 8.8 SIMULATING TEMPERATURE 8.8.1 General. The Solu Comp II accepts either a Pt100 or a Pt1000 RTD in a three-wire configuration. See Figure 8-5. 8.8.2 Simulating temperature To simulate the temperature input, wire a decade box to the analyzer or junction box as shown in Figure 8-6. To check the accuracy of the temperature measurement, set the resistor simulating the RTD to the values indicated in the table and note the temperature readings.

MODEL SOLU COMP II SECTION 8.0 TROUBLESHOOTING 8.9 MEASURING REFERENCE VOLTAGE Some processes contain substances that poison or shift the potential of the reference electrode. Sulfide is a good example. Prolonged exposure to sulfide converts the reference electrode from a silver/silver chloride electrode to a silver/silver sulfide electrode. The change in reference voltage is several hundred millivolts.
