4. סעטאַפּ
The VOLTCRAFT LWT-100 is designed for immediate use. It operates on an internal power source and does not require user-replaceable batteries. Follow these steps for initial setup:
- אויספּאַקן: Carefully remove the meter from its packaging.
- ערשט דורכקוק: Check the device for any visible damage. If damaged, do not use and contact customer support.
- מאַכט אויף: Press the power button (usually indicated by a power symbol or a specific button on the front panel) to turn on the device. The display should illuminate.
- זעלבסט-טעסט: The device may perform a brief self-test upon startup. Wait for the display to show stable readings or a ready indicator.
5. אַפּערייטינג ינסטרוקטיאָנס
The LWT-100 allows for quick and accurate measurement of conductivity, salinity, and TDS. Ensure the measuring cell is clean before each use.

- צוגרייטן סampלאַ: זיכער מאַכן אַז די פליסיקייט איזample is at a stable temperature and free of large particles that could obstruct the sensor.
- Immerse Sensor: Carefully immerse the graphite measuring cell (located at the bottom of the device) into the liquid sample. Ensure the sensor is fully submerged and no air bubbles are trapped around it.
- לייענען ווייַז: Wait for the reading on the display to stabilize. The device will show the conductivity value (e.g., in µS/cm or mS/cm) and the temperature.
- רעקאָרד דאַטן: Note down the measured values as needed.
- ריין סענסער: After each measurement, rinse the measuring cell with distilled or deionized water to prevent contamination and residue buildup.
5.2 Changing Measurement Modes (if applicable)
The LWT-100 can measure conductivity, salinity, and TDS. Use the designated mode button (refer to the button labels on your device, typically indicated by an arrow or 'MODE' symbol) to cycle through the available measurement modes. The active mode will be indicated on the display.
6. וישאַלט
Proper maintenance ensures the longevity and accuracy of your VOLTCRAFT LWT-100.
- Cleaning the Measuring Cell: After each use, rinse the graphite measuring cell thoroughly with distilled or deionized water. For stubborn residues, gently wipe the electrodes with a soft, lint-free cloth. Do not use abrasive materials or harsh chemicals.
- רייניקונג די גוף פון די מיטל: ווישן די יקסטיריער פון די מיטל מיט אַ ווייך, דamp שטאָף. דו זאלסט נישט נוצן סאָלוואַנץ אָדער שטאַרק דיטערדזשאַנץ.
- סטאָרידזש: Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the measuring cell is clean and dry before storage.
- קאליבראציע: While the LWT-100 is designed for high accuracy, periodic calibration with known conductivity standards may be required for critical applications. Refer to specific calibration instructions if provided with your device or consult VOLTCRAFT support.
