00809-0100-3200February 2019
Section 4: Calibration
4.1Calibration
1.Select two stable buffer solutions. Ideally, the calibration buffers should bracket the
expected pH of the sample and be at least two pH units apart. Use the ring at the bottom
of the back plate to hold the beaker containing the buffer.
2.Most pH meters offer automatic buffer recognition. Automatic buffer recognition means
the instrument automatically calibrates using the correct pH for the buffer temperature.
(The pH of a buffer, particularly one with alkaline pH, changes as the temperature
changes.) If the meter does not have automatic buffer recognition, refer to the label on the
buffer bottle for a table of pH versus temperature.
3.Remove the sensor from the flow cell and rinse it with deionized water. Immerse it in the
first buffer. Be sure the capillary disc is completely submerged. Gently swirl the sensor in
the buffer for a few seconds. Allow the sensor and buffer to reach the same temperature.
Once pH readings are stable, start the calibration. Follow the procedure in the transmitter
Reference Manual.
4.After the sensor has been calibrated in the first buffer, remove and rinse it with deionized
water. Place the sensor in the second buffer and complete the calibration.
5.After the calibration is complete, check the slope and intercept of the sensor. The slope
should be between 56 and 60 mV/pH and the offset should be between -20 and 20 mV.

Section 5: Maintenance
5.1Replacing the Electrolyte Solution (PN 9210391)
The reference electrolyte solution should last two to three months.
To replace the electrolyte solution:
1.Remove the reservoir bottle from the clip on the back plate. Turn the bottle upright.
2.Unscrew the cap without disconnecting the filter or electrolyte tube. To avoid twisting the
electrolyte tube, turn the bottle, not the cap. To keep the cap and air inlet tube clean,
hang the cap from the reservoir clip using the electrolyte tube.
3.Discard any remaining fill solution.
4.Pour 500 mL of new reference fill solution (PN 9210391) into the reservoir.
5.Replace the cap. Remember to turn the bottle, not the cap.
6.Invert the bottle and reattach it to the clip.
7.Bleed air bubbles from the tube and sensor. Refer to step 11 in the Putting the Rosemount
3200HP Sensor in Service (Section 2.3)
5.2Replacing the Capillary Disc (PN 34142-00)
The reference capillary is protected by two filters, one on the inside of the disc and the other on the
sample side. During normal operation, suspended solids in the sample coat the filter and hinder
flow through the capillary. Occasionally, bacterial or fungal growth in the electrolyte solution will
coat the inside filter. Eventually, as the coating builds up, the electrolyte flow becomes too low
and the capillary disc must be replaced. The typical symptom of a blocked capillary disc is
abnormally low use of electrolyte (500 mL of electrolyte should last no more than two months) or
pH readings significantly lower (0.5 pH) than expected.
The capillary disc will also become blocked if the filters are allowed to dry out. Dried out filters
cannot be rehydrated. They must be replaced.
To replace a capillary disc:
1.Lift the electrolyte reservoir out of the clip on the back plate. Turn the bottle upright and
disconnect the electrolyte tube from the filter. Place the shipping plug on the filter.
2.Disconnect the VP cable from the sensor and remove the sensor from the flow cell.
3.Hold the sensor in a horizontal position with the capillary disc pointing up. Use a small
screwdriver to gently pry the disc and O-ring out of the gland. Take care not to scratch the
gland. See Figure 5-1.
4.Remove the replacement capillary disc and O-ring from the container. Be careful not to
touch the white filter membrane portion of the disc with your fingers. Wear latex gloves
if necessary.
5.Place the sealing O-ring on the back side of the replacement capillary disc. See Figure 5-
1. Put the disc aside in a clean place. Keep the capillary disc wet. If the disc dries out it cannot
be rehydrated and must be replaced.
Maintenance13
MaintenanceReference Manual
February 201900809-0100-3200
6.Fill the reference junction port with electrolyte solution or deionized water until the level
slightly overflows the port.
7.Place the new capillary disc with the sealing O-ring facing down in the port. Use your finger
tips – do not let your bare fingers touch the white filter membrane – to push the capillary
disc straight into the port. See Figure 5-1. If inserting the disc is difficult, place the open
end of a clean ¼ inch compression fitting nut on the transparent portion of the disc and
push the disc into place by gently press straight down on the nut.
8.Reconnect the VP cable to the sensor. Place the sensor back in the flow cell and reattach
the electrolyte tube to the reservoir filter.
9.Slide the reservoir back into the clip.
10.Bleed air bubbles from the tube and sensor. Refer to step 11 in the Putting the Rosemount
3200HP Sensor in Service (Section 2.3)
