5. Add the filling solution to the probe as necessary (refer to Fill the probe

on page 11). The filling solution must be above the standard solution or the sample

level during measurement or calibration ( Figure 2

).

6. Make sure that the filling hole is open during measurement for the correct flow of the filling solution.

Note: For the best stabilization time, condition the probe for 2 hours in pH buffer 4.01 before use, if the probe was not used for 3 weeks or more. In low ionic strength (LIS) samples, condition the probe for a maximum of 5 minutes in the sample before use. In all other cases a condition before use is not necessary.

Before calibration:

The probe must have the correct service-life time stamp. Set the date and the time in the meter before the probe is attached.

It is not necessary to calibrate again if a calibrated probe is moved from one HQd meter to another. Make sure that the additional meter is configured to use the same calibration options.

To view the calibration data, push , then select View Probe Data>View Current Calibration.

If two probes are connected, push the UP or DOWN arrow to change to the single display mode to show the Calibrate option

(available only on HQ40d and HQ440d meters).

Prepare the probe for use (refer to Preparation for use

on page 2).

Calibration notes:

• Use buffers that are two pH units apart.

• Select additional standard sets with the minimum number of calibration points in the

Calibration Options. For a two-point calibration, select: one buffer with a pH above and one buffer with a pH below the sample pH. For a one-point calibration, select the buffer nearest to the sample pH.

• The calibration is recorded in the probe and the data log. Send the calibration to a

PC, a printer or a flash memory stick if connected.

3

• Air bubbles under the sensor tip can cause a slow response or an error in the measurement. If there are bubbles under the sensor tip, carefully shake the probe to remove the bubbles.

• Make sure that the filling hole is open and above the sample solution level.

• Use a laboratory stirrer or shake the probe from side to side in the solution to refresh the reference junction.

• The meter display shows "Stabilizing" and a progress bar as the probe stabilizes in the standard. The display shows the buffer and the temperature corrected pH value when the measurement is stable.

• The calibration and sample measurement conditions must be as similar as possible

(e.g., the temperature of the solution, the stir procedure, the stir rate and the position of the probe).

•

If a calibration error occurs, refer to Troubleshooting on page 12.

Calibration procedure:

1. Connect the probe to the meter. Make sure that the cable locking nut is correctly connected to the meter. Set the meter to on.

2. Push Calibrate.

Sample requirements

N O T I C E

Some probes are not compatible with specific sample types. Probe damage can occur.

• Samples must be aqueous. The probe can also make measurements in partially aqueous or some water-miscible solvents. Read the results with caution because the full pH scale changes when the solvent system changes.

• Probes with an Ag/AgCl reference system and a single junction are not compatible with solutions that contain silver complexing or binding agents (e.g., TRIS, proteins and sulfides). To measure in these solutions, use a double junction probe, a probe with an Ag

+

(silver ion) barrier or a Red Rod

*

probe.

• Proteins can collect on the sensing element. Make sure that the probe stays clean when these types of samples are measured.

• Do not use the probe in solutions that are out of the temperature range of the probe.

Refer to Specifications on page 1.

• For low ionic strength (LIS) or high purity samples, use an LIS chamber or a flow cell to prevent sample contamination.

Measurement

Before measurement:

The probe must have the correct service-life time stamp. Set the date and the time in the meter before the probe is attached.

If the complete traceability is necessary, enter a sample ID and an operator ID before the measurement. Refer to the HQd meter manual for more information.

A regular calibration is necessary for the best measurement accuracy (refer to

Calibration

on page 3).

Prepare the probe for use (refer to Preparation for use

on page 2).

Measurement notes:

• Data is automatically stored in the data log when Press to Read or Interval is selected in the Measurement Mode. When Continuous is selected, data is only stored when Store is pushed.

• Air bubbles under the sensor tip can cause a slow response or an error in the measurement. If there are bubbles under the sensor tip, carefully shake the probe to remove the bubbles.

• For the best stabilization time, condition the probe for several minutes in the sample or in a solution comparable to the sample in terms of pH and ionic strength before the initial sample measurement.

• Do not put the probe on the bottom or sides of the container.

• Make sure that the filling hole is open and above the sample solution level.

• Use a laboratory stirrer or shake the probe from side to side in the solution to refresh the reference junction.

• The meter display shows "Stabilizing" and a progress bar as the probe stabilizes in the sample. The display shows the lock icon when the measurement is stable.
