Што ў скрынцы
Пасля адкрыцця ўпакоўкі пераканайцеся, што ў камплекце ёсць усе наступныя прадметы:
- 1 x Arendsace 4-in-1 TDS Meter (white)
- 1 х Інструкцыя па эксплуатацыі
- 1 х каляровая скрынка
- 2 x LR44 Batteries (pre-installed or included separately)
Асаблівасці прадукту
- Accurate and Reliable Readings: Equipped with smart high-precision intelligent chips and high-quality titanium alloy probes for stable and accurate detection.
- 4-у-1 шматфункцыянальнасць: Measures Total Dissolved Solids (TDS), Electrical Conductivity (EC), and temperature in both Celsius (℃) and Fahrenheit (℉).
- Intelligent Backlit Display: Features a large, easy-to-read backlit screen, ideal for low-light or dark environments. The screen changes color based on TDS levels: green for values below 40ppm and red for values exceeding 40ppm.
- Automatic Lock Function: Automatically locks detected values, eliminating the need for manual button presses to hold readings.
- Энергазберажэнне: Automatically shuts down within 2 minutes of inactivity to conserve battery life.
- Шырокі спектр прымянення: Suitable for testing drinking water purity, checking the efficiency of reverse osmosis (RO)/DI systems, hydroponic nutrient solutions, swimming pools, spas, and general daily water testing.

Настройка
- Ўстаноўка батарэі: The device comes with 2 LR44 batteries included, which may be pre-installed. If not, locate the battery compartment cover at the top of the meter (as shown in the diagram). Carefully remove the cover and insert the batteries, ensuring correct polarity. Replace the cover securely. Note: Some users have reported the battery compartment cover can be tight; gentle prying with a flat, non-abrasive tool may be necessary if it's difficult to open.
- Protective Cover Removal: Before use, gently pull off the black protective cover from the bottom of the meter to expose the electrodes.
- Першапачатковая ўборка: It is recommended to rinse the electrode probe with distilled water before the first use to remove any manufacturing residues.
Інструкцыя па эксплуатацыі
- Падрыхтаваць Сampль: Наліце ваду сample you wish to test into a clean container.
- Уключэнне: Націсніце ON/OFF HOLD button to turn on the meter. The display will illuminate.
- Immerse Probe: Dip the electrode probe into the water sample, ensuring the water level is between the minimum and maximum water level marks indicated on the meter. Do not immerse the entire meter.
- Вымярэнне зчытаных дадзеных: Wait for the reading to stabilize (typically a few seconds). The meter will automatically lock the reading.
- Пераключэнне рэжымаў: Націсніце РЭЖЫМ button to cycle through the four detection modes:
- Рэжым 1: TDS (Total Dissolved Solids) in ppm (parts per million)
- Рэжым 2: EC (Electrical Conductivity) in µS/cm (microsiemens per centimeter)
- Рэжым 3: Temperature in ℃ (Celsius)
- Рэжым 4: Temperature in ℉ (Fahrenheit)

- Выразнае чытанне: Націсніце ЯСНА button to reset the current reading before taking a new measurement.
- Індыкатар падсвятлення:
- If the TDS value is below 40ppm, the screen backlight will remain зялёны, indicating ideal drinking water quality (e.g., RO/DI system water).
- If the TDS value exceeds 40ppm, the screen backlight will turn чырвоны, prompting attention to higher dissolved solids.

- Выключэнне: The meter will automatically shut off after 2 minutes of inactivity. You can also manually turn it off by pressing and holding the ON/OFF HOLD кнопка.
Тэхнічнае абслугоўванне
- Чысты зонд: After each use, rinse the electrode probe thoroughly with distilled or purified water to prevent residue buildup.
- Dry Probe: Always dry the probe completely with a soft, clean cloth or tissue after rinsing to ensure accurate readings for future tests.
- захоўванне: Replace the protective cap over the electrode probe when not in use. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
- Замена батарэі: If the display becomes dim or the meter does not power on, replace the LR44 batteries.
Ліквідацыю непаладак
| праблема | Магчымая прычына | Рашэнне |
|---|---|---|
| Няправільныя паказанні | Dirty or damaged probe; low battery; improper calibration (though this model is factory calibrated and doesn't mention user calibration); air bubbles on probe. | Clean and dry the probe. Replace batteries. Gently tap the meter to dislodge air bubbles. |
| Лічыльнік не ўключаецца | Разраджаныя або няправільна ўсталяваныя батарэйкі. | Праверце палярнасць батарэек. Заменіце іх новымі батарэйкамі тыпу LR44. |
| Дысплей цьмяны або мігціць | Нізкі зарад батарэі. | Заменіце батарэі. |
| Reading fluctuates excessively | Няўстойлівы сample; air bubbles; electrical interference. | Забяспечце сample is still. Gently tap meter. Move away from strong electrical fields. |
