Manwal tal-Utent tas-Sonda Multiparametrika pH/EC/TDS ta' Hanna Instruments HI1285-6

1. Introduzzjoni

The Hanna Instruments HI1285-6 is a multiparameter probe designed for simultaneous measurement of pH, Electrical Conductivity (EC), and Total Dissolved Solids (TDS). This probe is specifically engineered as a replacement for the GroChek HI9813 meter, ensuring accurate and reliable readings for various applications, including hydroponics, agriculture, and environmental monitoring. This manual provides essential information for the proper setup, operation, and maintenance of your HI1285-6 probe.

2. Setup u Installazzjoni

Proper setup is crucial for accurate measurements. Follow these steps to install your HI1285-6 probe:

Spakkjar: Carefully remove the probe from its packaging. Inspect for any visible damage.
Konnettur: Ensure the probe's connector is clean and dry. Align the connector with the corresponding port on your compatible meter (e.g., GroChek HI9813).
Konnessjoni Sikura: Gently push and twist the connector until it is firmly seated. Avoid overtightening.
Pre-conditioning: Before first use, or after prolonged storage, immerse the probe tip in HI70300 storage solution for at least 30 minutes to hydrate the pH glass bulb.
Tlaħliħ: Rinse the probe tip with deionized water before and after each measurement.

3. Istruzzjonijiet Operattivi

The HI1285-6 probe is designed for use with compatible Hanna Instruments meters. Refer to your meter's instruction manual for specific operational procedures. General guidelines are provided below:

Kalibrazzjoni: Regular calibration is essential for accurate readings. Calibrate the pH, EC, and TDS functions according to your meter's instructions using fresh calibration solutions. The CAL Check feature, if supported by your meter, assists in verifying probe condition.
Kejl:
1. Għaddas il-ponta tas-sonda fl-sample solution, ensuring the sensing elements are fully submerged.
2. Gently stir the probe to remove any air bubbles and allow the reading to stabilize.
3. Record the stabilized readings from your meter.
Kumpens tat-Temperatura: The probe features built-in temperature compensation for accurate EC/TDS readings. Ensure your meter is set to the correct temperature compensation mode.

4. Manutenzjoni u Ħażna

Proper maintenance extends the life and accuracy of your probe:

Tindif:
- Wara kull użu, laħlaħ is-sonda sewwa b'ilma dejonizzat.
- If deposits are visible, clean the probe with a suitable cleaning solution (e.g., Hanna Instruments HI7061 for general purpose).
- Never scratch or rub the glass bulb or platinum sensors.
Ħażna:
- Always store the pH/EC/TDS probe with its tip immersed in HI70300 storage solution. Never store in deionized water.
- Ensure the protective cap is filled with storage solution and securely placed over the probe tip when not in use.
Electrolyte Level: For refillable probes (if applicable to your specific HI1285-6 variant), ensure the electrolyte level is maintained above the reference junction.

5 Issolvi l-problemi

If you encounter issues with your HI1285-6 probe, consider the following common problems and solutions:

Problema	Kawża Possibbli	Soluzzjoni
Unstable/Erratic Readings	Dirty probe tip Air bubbles on sensor Damaged probe Insufficient hydration	Clean probe with appropriate solution. Gently stir to dislodge bubbles. Spezzjona għal ħsara fiżika; ibdel jekk meħtieġ. Re-hydrate in storage solution for several hours.
Ħin ta' Rispons Bil-Mod	Dehydrated pH glass Clogged reference junction Sonda ta 'età	Soak in storage solution overnight. Clean with specialized cleaning solution. Consider probe replacement.
Incorrect Readings (after calibration)	Expired/contaminated calibration solutions Improper calibration procedure Damaged probe	Uża soluzzjonijiet ta 'kalibrazzjoni friski. Repeat calibration carefully following meter instructions. Inspect probe; replace if damaged.

If problems persist, contact Hanna Instruments technical support or your local distributor for further assistance.
