3. Setup
3.1 Battery Installation
- Locate the battery compartment on the back of the meter.
- Open the compartment cover.
- Insert four (4) AA batteries, ensuring correct polarity as indicated inside the compartment.
- Close the battery compartment cover securely to maintain the waterproof seal.
3.2 Electrode Connection
- Carefully remove the protective cap from the SenTix 41 pH Electrode.
- Connect the electrode cable to the designated port on the WTW pH 3310 meter. Ensure the connection is firm and secure.
- Rinse the electrode with distilled water before initial use.
3.3 Initial Power-On
Press the ON/OFF button to power on the meter. The display will illuminate, and the device will perform a self-test before entering measurement mode.
4. Operating Instructions
4.1 Calibration
Regular calibration is essential for accurate pH measurements. The WTW pH 3310 supports up to 5-point calibration using DIN, NIST, or USA buffer recognition.
- Prepare fresh calibration buffer solutions (e.g., pH 4.01, 7.00, 10.00).
- Press the CAL button to enter calibration mode.
- Rinse the electrode with distilled water and immerse it in the first buffer solution.
- Wait for the reading to stabilize, then confirm the calibration point as prompted by the meter.
- Repeat for subsequent buffer solutions.
- The meter will automatically recognize the buffer and store the calibration data.
4.2 Measurement
- Ensure the meter is calibrated.
- Rinse the electrode with distilled water and immerse it in the sample solution.
- Wait for the reading to stabilize on the LCD. The AutoRead (AR) function can assist in determining when the reading is stable.
- Record the pH and temperature values displayed.
4.3 Data Logging
The pH 3310 meter offers advanced data logging capabilities:
- Manual Storage: Press the STO button to manually store the current measurement. The meter can store up to 5000 data sets.
- Time-Controlled Datalogging: Access the menu to set adjustable intervals for automatic data collection. This is ideal for long-term field monitoring.
- Sleep Mode: During long-term monitoring, the special "sleep" mode conserves battery power.
- Non-Volatile Memory: All logged data is saved permanently, even if the batteries are depleted or removed.
4.4 Data Transfer to PC
To transfer stored data to a computer:
- Connect the WTW pH 3310 meter to a PC using a mini-USB cable.
- The meter's waterproof USB interface ensures reliable connection.
- Follow the instructions in the accompanying software (if applicable) or the meter's menu to initiate data transfer.
5. Maintenance
5.1 Meter Care
- Clean the meter's keypad and housing with a damp cloth. Avoid abrasive cleaners.
- Ensure the battery compartment and USB port covers are securely closed when not in use to maintain waterproofing.
- Store the meter in its hard carrying case when not in use to protect it from damage.
5.2 Electrode Care (SenTix 41 pH Electrode)
- Always keep the electrode tip moist. Store it in its protective cap filled with appropriate storage solution (e.g., 3 mol/L KCl solution) when not in use. Never store in distilled water.
- Rinse the electrode with distilled water before and after each measurement.
- If the electrode becomes sluggish or readings are unstable, refer to the electrode's specific manual for cleaning and regeneration procedures.
- Replace the electrode when it no longer calibrates correctly or provides stable readings.
6. Troubleshooting
This section addresses common issues you might encounter with your WTW pH 3310 meter. For more detailed troubleshooting, refer to the full product manual or contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter does not power on. | Dead or incorrectly installed batteries. | Check battery polarity; replace with new AA batteries. |
| Unstable pH readings. | Dirty or damaged electrode; insufficient sample immersion; air bubbles. | Clean electrode; ensure proper immersion; gently stir to remove bubbles; recalibrate. |
| Calibration fails or is inaccurate. | Expired or contaminated buffer solutions; dirty electrode; incorrect buffer recognition setting. | Use fresh buffer solutions; clean electrode; check buffer recognition settings in the menu. |
| Data transfer to PC not working. | Loose USB connection; driver issues; incorrect software settings. | Ensure USB cable is securely connected; check PC device manager for drivers; consult software manual. |
