(Refer to Figure 1).
The HQd series meters are available in 3 models:
• HQ411d—pH/mV/ORP (Redox)
4 English

• HQ430d—Multi-parameter, single probe input
• HQ440d—Multi-parameter, dual probe inputs
Features common to all models:
• Automatic probe and parameter recognition
• Instrument guided calibration procedures
• Calibration data stored in the probe
• Probe specific method settings for regulatory compliance and Good Laboratory Practice (GLP)
• Security Options
• Real-time data logging with a USB connection
• USB connectivity to PC/printer/USB storage device/keyboard
• Bi-directional communication with PC-based systems with a virtual serial port connection
• Sample ID and Operator ID for data traceability

Installation
CAUTION
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
Connect to AC power
D A N G E R
Electrocution Hazard. AC power 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 for this
product is not sealed and must not be used on wet benches or in wet locations without GFCI protection.
The meter can be powered by AC power with the universal power adapter.
1. Set the meter to OFF.
2. Connect the AC/DC power supply to the meter. Refer to Figure 3.
3. Connect the AC/DC power supply to an AC receptacle.
4. Set the meter to ON.
Figure 3 AC power connection

Install the batteries
WARNING
Explosion hazard. Incorrect battery installation can cause the release of explosive gases. Be sure that the
batteries are of the same approved chemical type and are inserted in the correct orientation. Do not mix new and
used batteries.
N O T I C E
The battery compartment is not waterproof. If the battery compartment becomes wet, remove and dry the
batteries and dry the interior of the compartment. Check the battery contacts for corrosion and clean them if
necessary.
N O T I C E
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 charge, 2300 mAH NiMH batteries will achieve 90% of instrument operation
lifetime (before recharge) versus new alkaline batteries.
N O T I C E
To avoid potential damage to the meter from battery leakage, remove the meter batteries prior to extended
periods of non-use.
The meter can be powered with AA alkaline or rechargeable NiMH batteries. To conserve battery life,
the meter will power off after 5 minutes of inactivity. This time can be changed in the Display Options
menu.
For battery installation refer to Figure 4.
1. Loosen the three battery cover screws and remove the battery cover.
Note: Do not remove the screws from the battery cover.
2. Install 4 AA alkaline or 4 AA nickel metal hydride (NiMH) batteries. Make sure that the batteries
are installed in the correct polarity.
3. Replace the battery cover.
Note: Do not over-tighten the screws.

Standard operation
About calibration
Each probe uses a different type of calibration solution. Make sure to calibrate the probes frequently
to maintain the highest level of accuracy.
Note: For step-by-step instructions, refer to the documents that are included with each probe.
The calibration icon can indicate that:
• the calibration timer has expired
• the LDO sensor cap should be replaced
• the calibration is out of range
• the calibration results are outside acceptance criteria settings
About sample measurements
Each probe has specific preparation steps and procedures for taking sample measurements. For
step-by-step instructions, refer to the documents that are included with the probe.
About check standards
Run Check Standards verifies equipment accuracy by measuring a solution of a known value. The
meter will indicate if the Check Standard passed or failed. If the Check Standard fails, the calibration
icon is shown until the probe is calibrated.
The meter can be set to automatically show a reminder for check standard measurement at a
specified interval with a specified acceptance criteria. The reminder, value of the check standard, and
acceptance criteria can be changed. For step-by-step instructions, refer to the documents that are
included with the probe.

Data management
About stored data
The following types of data are stored in the data log:
• Sample measurements: stored automatically each time a sample is measured in the Press to
Read or Interval Mode. When the continuous measurement mode is used, data is stored only
when Store is selected.
• Calibrations: stored only when Store is selected at the end of a calibration. Calibration data is also
stored in the IntelliCAL (R) probe.
• Check standard measurements: stored automatically each time a check standard is measured (in
the Press to Read or Interval Mode).
When the data log becomes full (500 data points), the oldest data point is deleted when a new data
point is added. The entire data log can be deleted to remove data that has already been sent to a
printer or PC ( key > Delete Data Log). To prevent deletion of the data log by a user, use the
Security Options menu.
