General Information
1.2 Product Overview
1.3 Meter Description
The HQ Series Portable Meters measure various parameters when used with IntelliCAL™ probes such as pH, conductivity, salinity, total dissolved solids (TDS), or dissolved oxygen (using Hach's patented luminescent dissolved oxygen probes, LDO
®
). The meter automatically recognizes the type of probe that is connected to the meter. The probes store the unique serial number, current calibration, and calibration history. When the default settings are used, an operator can take measurements right out of the box.
Data is easily managed by using the settings for operator ID, sample ID, and data storage. Supervisory control can be set by using the access function. Settings for measurement and calibration are stored as methods. The default method for each parameter follows suggested USEPA measurement techniques.
The HQ series meters are available in four models:
•
HQ11d—pH/mV

AC Power and Batteries
DANGER
Use only alkaline or nickel metal hydride type batteries in the meter. Other battery types might cause a fire or explosion.
DANGER
Make sure that the batteries are installed according to the polarity markings in the meter battery compartment. Failure to correctly install the batteries can result in damage to the meter, fire, or explosion.
DANGER
AC mains outlets in wet or potentially wet locations MUST
ALWAYS be provided with a Ground Fault Circuit Interrupting
(GFCI/GFI) circuit breaker. The AC-DC power adapter provided with this product is not sealed and must not be used on wet benches or in wet locations without GFCI protection.
CAUTION
Never mix battery types in the meter. Use four AA alkaline, or four AA nickel metal hydride batteries.
Important Note: The battery compartment of the meter and the
USB/DC power adapter are not waterproof. Use care when operating these devices on a bench in wet environments. Water may infiltrate these devices and eventually cause performance or quality problems. Periodic inspection of the batteries and battery compartment is recommended, if the meter is used in wet environments: remove, clean, and dry the batteries, the interior of the battery compartment, and the battery contacts; then reinsert the batteries and close the compartment cover.
The meter can be battery powered using four AA batteries (alkaline or nickel metal hydride) or by AC power. Connection to AC power requires additional components (
3.2.1 Battery Power
Important Note: Rechargeable alkaline or nickel metal hydride batteries may also be used in the meter (do not mix battery types).
Batteries are not charged in the meter.

Release Tab
A battery icon appears in the top right corner of the display to indicate current battery status.
When batteries are installed, the meter will automatically shut off after five minutes of sitting idle (this is the default setting). This auto shut-off feature can be changed in the Display Options menu
(see
).
Note: When using nickel metal hydride (NiMH) batteries, the battery icon will not indicate a full charge after freshly charged batteries have been inserted (NiMH batteries are 1.2 V versus 1.5 V for alkaline batteries). Even though the icon does not indicate complete battery charge, if you use 2500 mAH NiMH batteries you will achieve 90% of instrument operation lifetime
(before you need to recharge) versus new alkaline batteries.
Note: NiMH batteries self-discharge during storage. If you do not insert freshly charged NiMH batteries, operational lifetime will be reduced from this 90%.
Note: As batteries age, their output voltage decreases. Whenever battery voltage drops below 4-volts, the meter will shut itself down, to assure no loss of data. Insert fresh batteries and meter functionality will be restored.

5.6 Archiving and Exchanging Methods (HQ40d only)
In addition to capturing real-time data and transferring data from the data log, user-created methods can be saved to a USB flash memory stick. These methods can then be archived to a PC or transferred to another HQd meter.
Whenever a flash memory stick is connected to a meter, a 'User' folder is created on the memory stick, and all user-created methods that are stored in the meter are archived to this folder.
When the memory stick is connected to another meter, all methods in the 'User' folder will be uploaded to the new meter. In addition, any user-created methods in the new meter that are not on the memory stick will be downloaded to the memory stick.
The method names will appear in the 'User' folder with a prefix by the parameter type and an underscore (e.g., LDO_, Cond_, pH_), and a file extension of .NGM. Only the METHOD NAME appears in the method library in the meter.
If a method on a meter has the same name as a method on a memory stick, the method in the meter will be overwritten. For example, if a file on the USB flash memory stick has the name
"LDO_SOUR TEST.NGM", this file will overwrite an LDO method on another meter with the same displayed method name (SOUR
TEST).
When a memory stick is connected to a PC, a user can delete or change the name of any method, or delete the entire 'User' folder on the memory stick. Method names that are changed must preserve the prefix (e.g. LDO_) and the file extension (.NGM). The
METHOD NAME is limited to 12 characters. Allowable characters in the METHOD NAME are A through Z, 0 through 9, and one or more spaces.
When a memory stick is connected to a meter, any user-created methods on the meter will be downloaded to the memory stick. The
'User' folder will be recreated each time the memory stick is connected. If the 'User' folder does not exist, a new 'User' folder will be created. The meter will not upload any methods from the memory stick if the 'User' folder does not exist or is empty.

Section 6 pH Operation and Methods
6.1 Calibrating the pH Probe
Note: Use pH buffer solutions to calibrate the pH probe. The minimum number required and values of the pH buffer solutions are specified in the
Calibration Options menu. A maximum of three buffers can be entered by using the “Color Coded” and DIN buffer sets. A maximum of four buffers can be entered by using the IUPAC buffer set.
Note: If using the HQ40d meter with two probes, the display must be in single display mode.
1. Press the
BLUE/LEFT
key under Calibrate.
2. The display will show the buffer values to be measured. These values are set in the Calibrations Options menu. Rinse the probe and place it in the first buffer solution. The probe automatically recognizes buffer values from a selected set, therefore entering the buffer values in a specific order is not required. However, it is recommended to begin with the lowest pH buffer for greatest accuracy.
3. Press the
GREEN/RIGHT
key under Read. The meter will automatically detect which buffer is being measured.
When the reading is stable, the display will highlight the buffer that has been read and display the temperature corrected pH value.
Temperature correction is automatic: the displayed pH is the true pH value of the buffer at the measured temperature.
4. Rinse the probe and place it in the next buffer solution.
5. Press the
GREEN/RIGHT
key under Read.
6. Repeat this procedure until the minimum number of calibration points specified in the pH Method have been acquired.
7. When the minimum number of buffer points are collected, Done appears above the
UP
key. Continue calibrating with the
Method-specified calibration buffers (up to the maximum number specified in the pH Method), until all have been used, or press the
UP
key to review the Calibration Summary.
41
pH Operation and Methods
8. The Calibration Summary will appear. Press the
GREEN/RIGHT
key under Store to accept the calibration and return to measurement mode. The calibration is recorded in the
500-result data log. For an HQ40d model, the calibration information is also sent to a PC/printer/flash memory stick if connected.
9. When the calibration is successful, the display will show OK in the upper left corner. The icon will appear as a question mark if the calibration information has expired or if a check standard has failed or been delayed.
6.1.1 Calibration Errors
6.1.1.1 Standard Not Recognized
If the mV reading of the buffer does not fall within the limits set for auto detection, the display will show “Standard not recognized.” If this happens, perform the following steps:
1. Rinse the probe and place it in a fresh buffer solution.
2. Press the
GREEN/RIGHT
key under Read. If the meter still does not recognize the buffer, be sure that the buffers used are the ones specified for the method. If so, refer to the probe instruction sheet for cleaning and troubleshooting procedures.
6.1.1.2 Slope Error
If the calibration slope does not meet the acceptance criteria, the display will show “Slope out of range”. If this happens, perform the following steps:
1. Obtain fresh buffer solutions. Rinse the probe and repeat the calibration.
2. If the meter still gives a Slope error, be sure the buffers that are used are the ones specified for the method. If the error continues, there may be a problem with the probe.
42
pH Operation and Methods
6.2 Taking a pH Measurement
If complete traceability is required, set the Sample ID and
Operator ID before taking a measurement.
Note: The default setting for Measurement Mode is “Press to Read”. If a different mode is required, change the Measurement Mode (see
1. Place the pH probe into the sample.
2. Press the
GREEN/RIGHT
key under Read.
3. The display will show “Stabilizing…” and a progress bar will fill from 0 to 100% as the probe stabilizes in the sample. Stability is determined by using a fixed change in the signal/time equation.
The lock icon will appear and the result will be automatically stored in the 500-result data log.
4. To take another measurement, repeat this procedure.
6.3 Running Check Standards Manually or Automatically
The Run Check Standards option for pH verifies reading accuracy by measuring a buffer solution of known pH and comparing actual values to theoretical values. When the probe is placed in the solution, the meter will indicate if the check standard passed or failed based on user-selected criteria.
A check standard can be measured at any time by using the
Meter
Options
menu or at specific intervals. Set the criteria for Check
Standards from the
Meter Options
menu.
Note: Access Control must be off or a valid password entered to change the acceptance criteria.
When the Check Standard reminder is ON, the meter will automatically display the Check Standard screen. The check standard can either be measured immediately, or be delayed and measured at a later time (this is a user-specified option, see
Parameter Methods
in
).
To measure the Check Standard:
1. Obtain the pH buffer solution specified for the check standard.
The buffer solution to be used is shown in the display.
2. Place the probe in the buffer solution.
3. Press the
GREEN/RIGHT
key under Read.
43
pH Operation and Methods
4. The display shows the value of the check standard and either
“Check Standard Passed” or “Check Standard Failed” appears.
If “Check Standard Passed” appears, the success criteria has been met, and the measurement has been verified to be accurate. Press the
GREEN/RIGHT
key under Done to proceed with sample measurements.
5. If “Check Standard Failed” appears, the measurement is outside of the accepted limits.
If the acceptance criteria is set to “Cal Expires on Failure: Yes”, the instrument will display the

8.1 Taking a Dissolved Oxygen Measurement
If complete traceability is required, enter a Sample ID and
Operator ID before measuring.
Note: The default setting for Measurement Mode is “Press to Read”. To
change the mode, see Measurement Mode in section 9.5 on page 84 .
Important Note: A count down message appears on the screen thirty days before the sensor-cap expiration date. This message will continue to display until there are zero days remaining and the sensor cap must be replaced. All measurements taken after the sensor cap expiration date appear with the calibration ? icon at the top left corner of the screen.
1. Place the LDO probe into the sample.
2. Press the
GREEN/RIGHT
key under Read.
3. The display will show “Stabilizing…” and a progress bar will fill from 0 to 100% as the probe stabilizes in the sample. When the result has stabilized, the lock icon will appear and the result will be stored automatically in the data log.
4. To make another measurement, repeat this procedure.
The display will also show the temperature and pressure. If a salinity correction was entered, the correction will appear on the display.
8.2 Calibrating the LDO Probe
Important Note: Factory calibration is the default setting. Factory calibration coefficients are stored in the iButton
®
*. Each lot of LDO sensor caps is factory calibrated. Performance will vary slightly as a function of usage history. For best performance, a one-time calibration initialization can be performed when a new sensor is installed. Additional calibrations can be performed at the operator's discretion but are not required. Manually calibrating the LDO probe will require creating and modifying a new method (see
).
LDO calibration can be performed manually using one of two standards:
•
Water-saturated air (recommended). For example, use a bottle with a narrow neck such as a BOD bottle (Cat. No. 621-00).
Add a small amount (1-cm) of water to the bottle, stopper and shake vigorously for several minutes, then insert the probe.
•
A water sample with a known dissolved oxygen concentration.
The concentration must be determined by Winkler titration, or by calculation of a saturated-air water sample using existing pressure, temperature, and salinity conditions.
Note: Modify the LDO Method to use a water sample as a standard.

8.4.5 Selecting a LDO Calibration Setting
Important Note: Factory calibration is the default setting. Factory calibration coefficients are stored in the iButton.
Water-saturated air is recommended for calibration of the HQ series meters, however a water sample with a known dissolved oxygen concentration can also be used. The dissolved oxygen concentration must be determined by Winkler titration, or by calculation of a saturated-air water sample using existing pressure, temperature, and salinity conditions.
Note: Factory calibration is the default setting. For information about manual calibration, see
.
Each lot of LDO sensor caps is factory calibrated. Performance will vary slightly as a function of usage history.
