6.1. pH PROBE (HI829113)

• Remove the protective cap. Do not be alarmed if salt deposits are present, this is normal. Rinse the
probe with water.

• Shake the electrode down as you would do with a clinical thermometer to eliminate any air bubbles
inside the glass bulb.

• If the bulb and/or junction are dry, soak the electrode in HI70300 storage solution for a minimum
of 30 minutes. Rinse with water.

• Calibrate before using.

• When the electrode is not in use, add a few drops of HI70300 storage solution to the protective cap
and replace the cap. To ensure a quick response, the glass bulb and the junction should be kept
moist and not allowed to dry out.

Note: Never store the electrode in distilled or deionized water.

6.2. DO PROBE (HI764103)

PROBE CONDITIONING & MAINTENANCE

The HI764103 is shipped dry. To hydrate the probe and prepare it for use:

• Remove the black & red plastic cap. This cap is used for shipping purposes only and can be thrown
away.

• Insert the O-ring in the membrane.

• Rinse the supplied membrane (HI76409A) with electrolyte while shaking it gently. Refill with clean
electrolyte.

• Gently tap the membrane over a surface to ensure that no air bubbles remain trapped. To avoid
damaging the membrane, do not touch it with your fingers.

• With the sensor facing down, screw the cap clockwise to the end of the threads. Some electrolyte
will overflow.

The same procedure is used to replace the electrolyte monthly and membrane every 2 months.

Press Menu to enter the main setup menu, use the / keys to highlight Calibration and then
press Select.

8.1. pH PROBE CALIBRATION (HI829113)

All calibration data is stored on the probe, allowing probes to be connected to different meters without
recalibration.
It is recommended to calibrate the instrument frequently, especially if high accuracy is required.
More frequent calibrations may be required depending on the type of sample being tested, i.e. turbid
biologically active water samples will require more frequent cleanings and calibrations than cleaner
waters.
The probe should be recalibrated:

• Whenever the probe is replaced.

• At least once a week.

• After testing aggressive samples.

• After cleaning the sensor.

• If “Outside Cal Range” message blinks during measurement (the measurement is outside the
current calibration range).

• If enabled, when the “CAL DUE” calibration time out message is displayed.

pH CALIBRATION

From the Calibration menu, use the / keys to highlight pH and then press Select.

CALIBRATION

Calibrate pH allows the user to perform a new calibration using up to three buffers. When a three­point calibration is performed the existing data is overwritten. A single or two-point calibration will
use existing calibration data, if available. Use the / keys to highlight Calibrate pH and then
press Select.

PREPARATION

Pour small quantities of the buffer solutions into clean beakers. If possible, use plastic beakers to
minimize any EMC interferences. For accurate calibration and to minimize cross-contamination, use
two beakers for each buffer solution: one for rinsing the electrode and one for calibration.

19

CALIBRATION

PROCEDURE

The measured pH value is displayed, along with the temperature and the buffer value on the second level.

• To change the buffer value, press the Cal. point, use the / keys to select the new buffer, press
Select to use the highlighted value.

• Submerse the tip of the pH electrode approximately 3 cm (1¼”) into the first buffer rinse solution
and stir gently.

• Submerse the tip of the pH electrode approximately 3 cm (1¼”) into the first buffer solution and
stir gently. The “Not Ready” message is displayed.

• Once the reading has stabilized, the countdown timer will count down until the display shows the
“Ready” message.

• Press Confirm to accept the calibration point.

• To save a one or two-point calibration, press ESC after the calibration buffer has been confirmed.

• Repeat the steps above to add a second or third point to the calibration.

• Press OK to return to the Calibration menu.

• Press Measure to return to the measurement screen.

CUSTOM BUFFER CALIBRATION

To select the custom buffer:

• Press Cal. Point, then Custom.

• Use the alphanumeric keypad to enter the value at the current temperature, then press Accept.

20

Note: The custom buffer can only be used as the first calibration point.

pH CALIBRATION ERROR MESSAGES

If the meter does not accept a pH calibration point, a short message is displayed to indicate the
possible error source.

Problems which arise during calibration can have different sources: the sensor, measuring temperature,
buffer solutions etc. Special note should be taken of the symptoms of the problem as these are useful
for locating the source of the problem.

• “Input out of scale”: the pH value is out of range. The pH sensor may require replacement.

• “Check sensor”: the electrode may be broken, very dirty or the user has attempted to calibrate the
same buffer value twice.

• “Wrong buffer”: the displayed pH reading is too far from the selected buffer value. This is often
seen immediately after a buffer calibration has been completed but before the pH sensor has been
moved to the next buffer. Check if the correct calibration buffer has been selected.

• “Invalid temperature”: the buffer temperature is outside the acceptable range.

• “Wrong buffer” / “Contaminated buffer” / “Check electrode”: the buffer is contaminated or the
sensor is broken or very dirty.

• “Check sensor” / “Clean sensor”: the electrode is broken or very dirty.

• “Wrong” / “Clear old calibration”: erroneous slope condition. These messages appear if the slope
difference between the current and previous calibration exceeds the slope window (80% to 110%).
Press the Clear softkey to clear the previous calibration data and continue the calibration, or press

ESC to quit the pH calibration mode.

RESTORING FACTORY CALIBRATION

When a new pH probe is being used, some of the error and warning messages are based on the
previous calibration. Restoring factory calibration will delete the user calibration and restore the
factory default calibration. Use the / keys to highlight Restore factory calib. and then press
Select.

8.2. DO PROBE CALIBRATION (HI764103)

It is recommended to calibrate the instrument frequently, especially if high accuracy is required.
More frequent calibrations may be required depending on the type of sample being tested, i.e. turbid
biologically active water samples will require more frequent cleanings and calibrations than cleaner
waters.
The probe should be recalibrated:

• Whenever the probe or membrane is replaced.

• At least once a week.

• After testing aggressive samples.

• After cleaning the sensor.

• If “Outside Cal Range” message blinks during measurement (the measurement is outside the
current calibration range).

• If enabled, when the “CAL DUE” calibration time out message is displayed.

It is recommended to calibrate dissolved oxygen at the measurement site to prevent changes in
altitude and barometric pressure.

Note: If %DO saturation is calibrated, the DO concentration range will also be calibrated and
vice versa.
