Tatūnga me te Whakatau

1. Tāuta Pūhiko

1. Unscrew the battery compartment cap at the top of the device.
2. Whakauruhia nga pākahiko AAA e rua, kia tika te polarity.
3. Whakakapia mārire te taupoki o te wāhanga pākahiko.

2. Initial Calibration (3-Point Method)

For accurate readings, calibrate the pH meter before first use and periodically thereafter. The device uses a three-point calibration method (pH 4.01, 7.00, and 10.01).

1. Whakaritea ngā Otinga Pūwero: Dissolve one packet of pH 4.01, pH 7.00, and pH 10.01 calibration powder each into 250ml of distilled water to create your buffer solutions.
2. Horoia te Probe: Rinse the pH probe with distilled water and gently blot dry.
3. Tīmata Whakatau:
   • Turn on the meter by pressing the ON/OFF HOLD pātene.
   • Patohia me te pupuri i te CAL/A pēhi i te pātene kia puta rā anō te "CAL" ki te mata.
4. Calibrate pH 7.00:
   • Immerse the probe into the pH 7.00 buffer solution.
   • Wait for the reading to stabilize (usually indicated by a stable value on the screen). The meter will automatically recognize the buffer.
   • Once stable, the meter will indicate successful calibration for pH 7.00.
5. Calibrate pH 4.01:
   • Horoia te tirotiro ki te wai matutu.
   • Immerse the probe into the pH 4.01 buffer solution.
   • Wait for the reading to stabilize. The meter will automatically recognize the buffer.
   • Once stable, the meter will indicate successful calibration for pH 4.01.
6. Calibrate pH 10.01:
   • Horoia te tirotiro ki te wai matutu.
   • Immerse the probe into the pH 10.01 buffer solution.
   • Wait for the reading to stabilize. The meter will automatically recognize the buffer.
   • Once stable, the meter will indicate successful calibration for pH 10.01.
7. Whakaoti: After all three points are calibrated, the meter will display "PAS" (Pass) or a similar indication, then return to measurement mode.

Nga Tohutohu Whakahaere

1. General Measurement Procedure

1. Whakapaia te Sample: Me whakarite te sample (soil, solution, food, water) is ready for testing. For soil, ensure it is moist enough for the probe to penetrate easily.
2. Whakakā: Pehia te ON/OFF HOLD pātene ki te hiko i runga i te taputapu.
3. Kōkuhu Probe: Carefully insert the pH probe into the sample. For soil, use the alloy protective cap to assist in penetrating harder soil without damaging the probe. Ensure the probe tip is fully immersed or in firm contact with the sample.
4. Panui inenga: Wait for the reading on the LCD screen to stabilize. The display will show the pH value and temperature.
5. Pupuri Raraunga: Pehia te ON/OFF HOLD button briefly to freeze the current reading on the screen. Press again to release.
6. Mahi Whakaoho: If the pH value is below 3.5 or above 12, the LCD backlight will turn red to indicate an extreme acid or alkali environment.
7. Whakaweto: Patohia me te pupuri i te ON/OFF HOLD button to power off the device after use.

2. Using the Alloy Protective Cap

The unique zinc alloy protective cap is designed to safeguard the pH probe, especially when measuring in dense or hard materials like soil.

• Attach the cap to the probe before inserting into hard soil.
• The cap helps create a path, reducing the risk of damage to the delicate glass electrode.
• Ensure the probe tip is exposed through the cap for accurate readings.

Te tiaki

1. Whakapaipai i te tirotiro

• Always rinse the pH probe with distilled water after each use to remove any residue.
• Gently blot dry with a soft, lint-free cloth. Do not rub the glass bulb.

2. Te Rokiroki i te Pūnaha Whakamātautau

Proper storage is essential to maintain the probe's activity and prolong its lifespan.

• After cleaning, inject a small amount of potassium chloride (KCL) solution into the protective cap.
• Place the cap back onto the probe, ensuring the probe tip is immersed in the KCL solution.
• If KCL solution is unavailable, distilled water can be used for short-term storage, but KCL is recommended for long-term preservation.

3. Whakakapinga Pūhiko

When the battery indicator on the LCD screen shows low power, replace the AAA batteries as described in the "Battery Installation" section.
