4. راه اندازی

4.1 نصب باتری

The ANENG V7 Multimeter typically uses standard batteries (e.g., AA or 9V, check the battery compartment for specifics). To install or replace batteries:

1. Ensure the multimeter is turned OFF and disconnect all test leads from the input terminals.
2. پوشش محفظه باتری را در پشت دستگاه پیدا کنید.
3. از یک پیچ گوشتی برای باز کردن محفظه باتری استفاده کنید.
4. Insert new batteries, observing the correct polarity (+ and -).
5. درپوش محفظه باتری را تعویض کرده و آن را با پیچ محکم کنید.

۶.۲ اتصال سیم‌های تست

Always connect the black test lead to the "COM" (common) jack. Connect the red test lead to the appropriate input jack based on the measurement you intend to make:

• برای جلدtage, Resistance, Capacitance, Frequency, Diode, Continuity, and Temperature measurements: Connect the red lead to the "VΩHz-II+" jack.
• برای اندازه‌گیری جریان (mA/µA): سیم قرمز را به جک "mAµA" وصل کنید.
• For High Current (A) measurements: Connect the red lead to the "20A" jack.

5. دستورالعمل های عملیاتی

The ANENG V7 features both auto-ranging and manual mode capabilities. The intelligent recognition function simplifies operation for common measurements.

Figure 5.1: The intelligent anti-burn feature with smart recognition helps prevent damage from incorrect settings, especially when the rotary dial is set to 'AUTO'.

۴.۱ مراحل اندازه‌گیری اولیه

1. دکمه چرخان را روی عملکرد دلخواه بچرخانید (مثلاً V~ برای AC Vol)tage، V- برای ولتاژ DCtage, Ω for Resistance, etc.). For most common measurements, the "AUTO" setting will automatically detect the type of measurement.
2. Connect the test leads to the circuit or component you wish to measure, ensuring correct polarity and connection points.
3. Read the measurement value on the LCD display.
4. After measurement, disconnect the test leads from the circuit, then from the multimeter.
5. Turn the rotary dial to "OFF" when not in use to conserve battery life.

5.2 Specific Measurement Functions

• DC/AC Voltage Measurement (V-, V~):

  Set the rotary dial to V- (DC) or V~ (AC) or AUTO. Connect test leads in parallel to the circuit. The meter will display the voltagارزش e

• DC/AC Current Measurement (A, mA, µA):

  Set the rotary dial to the appropriate current range (A, mA, or µA). Connect the meter in series with the circuit. Ensure the circuit is de-energized before connecting the meter.

• اندازه‌گیری مقاومت (Ω):

  Set the rotary dial to Ω or AUTO. Ensure the circuit is de-energized. Connect test leads across the component. The meter will display the resistance value.
• Capacitance Measurement (F):

  Set the rotary dial to F or AUTO. Ensure the capacitor is discharged before measurement. Connect test leads across the capacitor terminals.

• اندازه گیری فرکانس (هرتز):

  Set the rotary dial to Hz or AUTO. Connect test leads to the signal source. The meter will display the frequency.

• تست دیود (→|):

  Set the rotary dial to the diode symbol. Connect the red lead to the anode and the black lead to the cathode. The meter displays the forward voltage قطره
• تست تداوم ()))):

  Set the rotary dial to the continuity symbol. Connect test leads across the circuit or component. A built-in buzzer will sound if the resistance is below a certain threshold (typically <50Ω).

• اندازه‌گیری دما (°C/°F):

  Set the rotary dial to TEMP. Connect the temperature probe (thermocouple) to the input jacks. Place the probe on the object to be measured.

• جلد بدون تماسtage (NCV) تشخیص:

  Set the rotary dial to NCV. Bring the top of the meter near a live AC voltage source. The meter will indicate the presence of AC voltagاز طریق یک بوق صوتی و/یا نشانگر بصری.

6. تعمیر و نگهداری

6.1 تمیز کردن

پاک کردن مورد با آگهیamp پارچه و مواد شوینده ملایم. از مواد ساینده یا حلال استفاده نکنید. ترمینال‌های ورودی را از آلودگی و رطوبت پاک کنید.

6.2 تعویض باتری

وقتی نشانگر باتری ضعیف روی صفحه نمایش ظاهر شد، باتری‌ها را فوراً تعویض کنید تا از خوانش دقیق اطمینان حاصل شود. برای دستورالعمل‌های نصب باتری به بخش ۴.۱ مراجعه کنید.

6.3 تعویض فیوز

اگر عملکرد اندازه‌گیری جریان از کار افتاد، ممکن است فیوز نیاز به تعویض داشته باشد. برای اطلاع از نوع و درجه‌بندی صحیح فیوز به مشخصات مراجعه کنید. تعویض فیوز فقط باید توسط پرسنل واجد شرایط انجام شود.

7 عیب یابی

• No Display / Power On Issue:

  Check battery installation and ensure batteries are not depleted. Replace if necessary. Ensure the rotary dial is not in the "OFF" position.

• قرائت های نادرست:

  Verify the correct function and range are selected. Check test lead connections. Ensure batteries are not low. Calibrate if necessary (advanced users only).

• Current Measurement Not Working:

  Check if the fuse for the current input is blown. Replace if necessary (refer to Section 6.3).
• Continuity Buzzer Not Sounding:

  Ensure the circuit is de-energized. Check for open circuits or high resistance. The buzzer typically activates for resistance below 50Ω.
