4. સેટઅપ

4.1. બેટરી ઇન્સ્ટોલેશન

  1. Open the battery compartment cover located on the rear of the device.
  2. યોગ્ય ધ્રુવીયતા (+/-) સુનિશ્ચિત કરીને, ઉલ્લેખિત બેટરીઓ દાખલ કરો.
  3. બેટરી કમ્પાર્ટમેન્ટ કવર સુરક્ષિત રીતે બંધ કરો.

4.2. ચકાસણી કનેક્શન

  1. Connect the pH electrode to the designated BNC connector on the device. Ensure a firm connection.
  2. Connect the temperature probe to its dedicated input jack.
  3. Ensure all connections are clean and dry before use.

5. ઓપરેટિંગ સૂચનાઓ

5.1. પાવર ચાલુ/બંધ

દબાવો ચાલુ/બંધ button to power on the device. Press and hold the ચાલુ/બંધ button for approximately 3 seconds to power off.

5.2. માપાંકન

Regular calibration is crucial for accurate measurements. Refer to the specific calibration procedure for pH and Redox measurements outlined below.

5.2.1. pH માપાંકન

  1. Prepare fresh pH buffer solutions (e.g., pH 4.00, 7.00, 10.00).
  2. Rinse the pH electrode thoroughly with distilled water and blot dry.
  3. Immerse the electrode in the first buffer solution (e.g., pH 7.00).
  4. Enter calibration mode as per the device's menu.
  5. Follow on-screen prompts to confirm the buffer value.
  6. Repeat for subsequent buffer solutions.

5.2.2. Redox Calibration

Redox electrodes typically do not require calibration in the same way as pH electrodes. However, their functionality can be checked using a known Redox test solution.

5.3. માપન લેવું

  1. ખાતરી કરો કે ઉપકરણ માપાંકિત થયેલ છે.
  2. Rinse the probe(s) with distilled water and blot dry.
  3. Immerse the probe(s) into the sample solution. Ensure the sensing part of the probe is fully submerged.
  4. Allow the reading to stabilize on the display.
  5. માપ રેકોર્ડ કરો.
  6. After measurement, rinse the probe(s) thoroughly and store according to maintenance guidelines.

6. જાળવણી

6.1. ઉપકરણને સાફ કરવું

Wipe the device housing with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure no liquid enters the device openings.

6.2. Probe Care and Storage

  • pH ઇલેક્ટ્રોડ: Always keep the pH electrode wet. Store it in a suitable storage solution (e.g., 3M KCl solution or pH 4 buffer). Never store in distilled water.
  • રેડોક્સ ઇલેક્ટ્રોડ: Store in a suitable storage solution or distilled water if not used for extended periods.
  • તાપમાન તપાસ: Clean with distilled water after each use.
  • Regularly inspect probes for damage or contamination.
