  • Page 47 MODEL FCLi-1056 SECTION 6.0 CALIBRATION SECTION 6.0 CALIBRATION 6.1 INTRODUCTION The calibrate menu allows the user to do the following: 1. Calibrate the temperature sensing element in the chlorine and pH sensors. 2. Calibrate the chlorine sensor. 3. Calibrate the pH sensor. Four methods are available.
  • Page 48 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.2.2 Procedure 1. Remove the sensor from the flow cell. Place it in an insulated container of water along with a calibrated thermometer. Submerge at least the bottom two inches of the sensor. 2. Allow the sensor to reach thermal equilibrium. The time constant for both the chlorine and pH sensor is about 5 min., so it may take as long as 30 min for equilibration.
  • Page 49 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.3 CALIBRATION — FREE CHLORINE 6.3.1 Purpose As Figure 6-1 shows, a free chlorine sensor generates a current directly proportional to the concentration of free chlorine in the sample. Calibrating the sensor requires exposing it to a solution containing no chlorine (zero standard) and to a solution containing a known amount of chlorine (full-scale standard).
  • Page 50 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 3. Press MENU. The main menu screen appears. The cursor will be on Calibrate. Press ENTER. 4. Choose the sensor you wish to calibrate. Sensor 1 is the chlorine sensor. Calibrate Sensor 2 (if present) is the pH sensor.
  • Page 51 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.3.2 Procedure-Calibrating the Sensor 1. Place the chlorine sensor in the chlorine flow cell. Adjust the sample flow until water overflows the inside tube in the constant head flow controller. 2. Adjust the chlorine concentration until it is near the upper end of the operating range. Wait until the analyzer reading is stable before starting the calibration.
  • Page 52 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.4 CALIBRATION – pH 6.4.1 Purpose A pH sensor consists of a glass and reference electrode. Usually, the two electrodes are combined into a single body, called a combination pH sensor. When the sensor is placed in an aqueous solution, it produces a voltage proportional to pH.
  • Page 53 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 5. USER ENTERED SLOPE AND OFFSET. If the slope and offset are known from other measurements, they can be directly entered in the analyzer. Enter the slope as a positive number corrected to 25ºC. To calculate the slope at 25ºC from the slope at temperature tºC, use the equation:...
  • Page 54 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 8. Choose Start Auto Cal. S2 pH Auto Cal Start Auto Cal Start Auto Cal If you wish to change the stability criteria or the pH buffer list from the Setup default values, choose Setup instead and go to step 14. The default stability is defined as a less than 0.02 pH change in 10 seconds.
  • Page 55 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.4.4 Procedure-Manual Calibration 1. Obtain two buffer solutions. Ideally, the buffer pH values should bracket the range of pH values to be measured. 2. Remove the sensor from the flow cell. If the process and buffer temperatures are appreciably different, place the sensor in a container of tap water at the buffer temperature.
  • Page 56 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 10. Watch the pH reading for sensor 2 (S2) at the top of the screen. Once Manual Buffer 1 the reading is stable, enter the pH value of the buffer at the buffer 0 7.00 pH temperature and press ENTER.
  • Page 57 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.4.5 Procedure-Standardization 1. The pH value measured by the 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. Place the sensor in the flow cell. Wait until pH readings are stable.
  • Page 58 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.4.6 Procedure-Entering a Known Slope and Offset 1. Calibration data, i.e., slope and offset at pH 7, can be entered directly into the analyzer if the data for the sensor are already known. 2. Press MENU. The main menu screen appears. The cursor will be on Calibrate.
  • Page 59 MODEL FCLi-1056 SECTION 6.0 CALIBRATION 6.5 CALIBRATION – Analog Outputs 6.5.1 Purpose Although the analyzer analog outputs are calibrated at the factory, they can be trimmed in the field to match the reading from a standard milliammeter. Both the low (0 or 4 mA) and high (20 mA) outputs can be trimmed.

  • Page 63 MODEL FCLi-1056 SECTION 8.0 MAINTENANCE SECTION 8.0 MAINTENANCE 8.1 ANALYZER The analyzer used with the FCLi needs little routine maintenance. Clean the analyzer case and front panel by wiping with a clean soft cloth dampened with water ONLY. Do not use solvents, like alcohol, that might cause a buildup of static charge.
  • Page 64 MODEL FCLi-1056 SECTION 8.0 MAINTENANCE 8.2 CHLORINE SENSOR 8.2.1 General. When used in clean water, the 498CL-01 chlorine sensor requires little maintenance. Generally, the sensor needs maintenance when the response becomes sluggish or noisy or when readings drift following calibration. For a sen- sor used in potable water, expect to clean the membrane every month and replace the membrane and electrolyte slurry every three months.

  • Page 78 MODEL FCLi-1056 SECTION 9.0 TROUBLESHOOTING 9.6.2 Calibration Error during Standardization. During standardization, the millivolt signal from the pH cell is increased or decreased until the pH agrees with the pH reading from a referee instrument. A unit change in pH requires an offset of about 59 mV. The analyzer limits the offset to ±60 mV.
  • Page 79 MODEL FCLi-1056 SECTION 9.0 TROUBLESHOOTING 9.6.5 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.
