    Even then, the error is small. For example, at pH 12 and 25°C, a 1°C error produces a pH error less than ±0.02. 2. During auto calibration, the Solu Comp II recognizes the buffer being used and calculates the actual pH of the buffer at the measured temperature.

    (STANDARDIZATION) 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 ref- eree 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 con- verted to pH.

  • Page 43: Entering A Known Slope

    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: slope at 25°C = (slope at t°C)

    In contrast, quinhydrone standards contain toxic quinhydrone and have only an eight-hour shelf life. Iron (II) - iron (III) standard is available from Rosemount Analytical as PN R508-16OZ. The ORP of the standard solution measured against a silver-silver chloride reference electrode is 476±20mA at 25°C. The redox potential is -476±20mA at 25°C.

    7.2 REPLACEMENT PARTS 7.1 OVERVIEW The Solu Comp II analyzer needs little routine maintenance. The calibration of the analyzer and sensor should be checked periodically. To recalibrate the analyzer and sensor, see Section 6.0. Clean the analyzer case and front panel by wiping with a clean soft cloth dampened with water ONLY. Do not use solvent, like alcohol, that might cause a buildup of static charge.

    8.2.4 RTD Sense Line for Sensor 1 or Sensor 2 is Open. The Solu Comp II measures temperature using a three-wire RTD inside the sensor. See Figure 8-3. The in and return leads connect the RTD to the measuring circuit in the analyzer. A third wire, called the sense line, is con- nected to the return line.
  • Page 50 During standardization, the millivolt signal from the pH cell is increased or decreased to force it to agree with the pH reading from a referee instrument. A unit change in pH requires an offset of about 59 mV. The Solu Comp II limits the offset to ±1400 mV.
  • Page 51 8.3.4 Invalid Input While Manually Entering Slope. If the sensor slope is known from other sources, it can be entered directly into the analyzer. The Solu Comp II will not accept a slope (at 25°C) outside the range 45 to 60 mV/pH. See section 8.3.2 for troubleshooting sensor slope problems.
