4.1 ബാറ്ററി ഇൻസ്റ്റാളേഷൻ

1. Ensure the meter is turned OFF by rotating the function switch to the 'OFF' position.
2. മീറ്ററിന്റെ പിൻഭാഗത്ത് ബാറ്ററി കമ്പാർട്ട്മെന്റ് കണ്ടെത്തുക.
3. Open the battery cover by sliding or unscrewing it (refer to Figure 2).
4. Insert one 9V battery, observing the correct polarity (+ and - terminals).
5. ബാറ്ററി കവർ സുരക്ഷിതമായി അടയ്ക്കുക.

4.2 ടെസ്റ്റ് ലീഡുകൾ ബന്ധിപ്പിക്കുന്നു

1. Insert the red test lead plug into the 'CX+' input terminal.
2. Insert the black test lead plug into the 'COM' input terminal.

This image shows the MEXTECH DT1503 meter with the red test lead connected to the 'CX+' terminal and the black test lead connected to the 'COM' terminal, ready for measurement.

5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

5.1 പവർ ഓൺ/ഓഫ്

To turn the meter ON, rotate the rotary function switch from the 'OFF' position to any desired measurement range. To turn the meter OFF, rotate the switch back to the 'OFF' position.

5.2 സീറോ അഡ്ജസ്റ്റ്മെൻ്റ്

Before performing any capacitance measurement, especially on lower ranges, it is crucial to perform a zero adjustment to eliminate stray capacitance from the test leads and internal circuitry.

1. Ensure the test leads are connected to the meter.
2. Short the tips of the red and black test leads together.
3. Rotate the 'ADJ' knob (located on the left side of the meter) until the display reads '000'.
4. This adjustment should be performed for each range if significant deviation from zero is observed.

5.3 ശേഷി അളക്കൽ

1. ഡിസ്ചാർജ് കപ്പാസിറ്റർ: Always ensure the capacitor to be measured is fully discharged before connecting it to the meter. Failure to do so can damage the meter or cause injury.
2. ശ്രേണി തിരഞ്ഞെടുക്കുക: Rotate the function switch to the appropriate measurement range. If the capacitance value is unknown, start with the highest range (20mF) and work downwards until a stable and accurate reading is obtained.
3. Connect Capacitor: Connect the test leads to the capacitor terminals. For polarized capacitors (e.g., electrolytic), connect the red lead to the positive terminal and the black lead to the negative terminal. For non-polarized capacitors, the connection order does not matter.
4. Read Value: The capacitance value will be displayed on the LCD screen in the selected unit (pF, nF, µF, or mF).

5.4 ഡാറ്റ ഹോൾഡ് പ്രവർത്തനം

To freeze the current reading on the display, press the 'HOLD' button. The 'HOLD' indicator will appear on the screen. Press the 'HOLD' button again to release the reading and resume live measurement.

5.5 ബാക്ക്‌ലൈറ്റ്

Press the 'LIGHT' button to activate the display backlight. This feature is useful for reading measurements in low-light conditions. The backlight will automatically turn off after approximately 10 seconds to conserve battery power.

6. Measurement Ranges and Accuracy

The MEXTECH DT1503 offers the following measurement ranges and typical accuracy specifications:

7. പരിപാലനം

7.1 വൃത്തിയാക്കൽ

To clean the meter, wipe the casing with a dry, soft cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the plastic components or electronic circuits.

7.2 ബാറ്ററി മാറ്റിസ്ഥാപിക്കൽ

When the low battery indicator appears on the display, the 9V battery needs to be replaced. Follow the steps outlined in Section 4.1 'Battery Installation'. Ensure the meter is OFF before replacing the battery.

7.3 ഫ്യൂസ് മാറ്റിസ്ഥാപിക്കൽ

If the meter fails to function or provides incorrect readings consistently, the internal fuse may need replacement. Fuse replacement should only be performed by a qualified technician to ensure the correct fuse type and rating are used. Opening the meter by unauthorized personnel may void the warranty.

8. പ്രശ്‌നപരിഹാരം

This section addresses common issues you might encounter with your MEXTECH DT1503 meter.

• ഡിസ്പ്ലേ ഇല്ല അല്ലെങ്കിൽ മങ്ങിയ ഡിസ്പ്ലേ:
  പരിഹാരം: Check the 9V battery. Ensure it is correctly installed and has sufficient charge. Replace the battery if necessary. Also, ensure the rotary switch is not in the 'OFF' position.
• തെറ്റായതോ അസ്ഥിരമായതോ ആയ റീഡിംഗുകൾ:
  പരിഹാരം: Perform a zero adjustment as described in Section 5.2. Ensure the test leads are properly connected and not damaged. Verify that the capacitor under test is fully discharged. Select the correct measurement range; if the range is too high for a small capacitor, the reading may be unstable or show '000'.
• Low Battery Indicator Appears:
  പരിഹാരം: Replace the 9V battery immediately to ensure accurate measurements and proper operation.
• Meter Does Not Respond:
  പരിഹാരം: Check the battery. If the battery is good, the internal fuse might be blown. Refer to Section 7.3 for fuse replacement. If the issue persists, contact customer support.
