اطلاعات ایمنی

Always read and understand all safety instructions before operating the multimeter. Failure to follow these warnings could result in serious injury or damage to the instrument.

• Do not touch the probes directly with your hands to avoid electric shock and ensure personal safety during testing.
• Before use, inspect the test probes to ensure there is no damaged insulation or exposed metal. Replace damaged test leads immediately.
• Do not use the current and voltage ranges interchangeably without understanding the circuit. Incorrect range selection can prevent damage to the instrument.
• هرگز حجم را اندازه نگیریدtage with the test leads connected to the current input jacks (10A or mA). This can severely damage the multimeter and pose a safety risk.
• If you do not know the magnitude of the voltage or current to be measured, start with the highest range and then select the appropriate range based on the measured value.
• Ensure the multimeter's CAT rating is appropriate for the circuit you are testing.
• اگر مولتی‌متر آسیب دیده یا به درستی کار نمی‌کند، از آن استفاده نکنید.

دستورالعمل های عملیاتی

عملیات عمومی

• روشن/خاموش برق: Rotate the function turntable from the 'OFF' position to any desired measurement function to turn on the multimeter. Rotate back to 'OFF' to power off.
• خاموش شدن خودکار: The instrument will automatically shut down after approximately 15 minutes of no operation to conserve battery life.
• نگهداری داده ها: Press the 'H' button to freeze the current reading on the display. Press 'H' again to release.
• انتخاب تابع: Use the rotary switch to select the main measurement function. For functions with multiple modes (e.g., AC/DC voltage, Diode/Continuity), press the 'SET' button to cycle through them.

توابع اندازه گیری

Always ensure the test leads are correctly inserted into the appropriate jacks for the desired measurement.

1. DC Voltagاندازه‌گیری الکترونیکی (V-)

برای اندازه گیری حجم DCtage, such as battery voltage:

1. کلید چرخشی را در موقعیت 'V~' قرار دهید.
2. If necessary, press the 'SET' button to ensure DC voltage mode is selected (indicated by 'DC' on the display).
3. Insert the red test lead into the 'INPUT' jack and the black test lead into the 'COM' jack.
4. Connect the test probes across the component or circuit to be measured. The display will show the voltage value. The multimeter can easily detect battery voltage and determine positive and negative electrodes; the red probe will display a '-' symbol when touching the negative electrode.

2. AC Voltagاندازه‌گیری الکترونیکی (V~)

برای اندازه گیری حجم ACtage:

1. کلید چرخشی را در موقعیت 'V~' قرار دهید.
2. Press the 'SET' button to ensure AC voltage mode is selected (indicated by 'AC' on the display).
3. Insert the red test lead into the 'INPUT' jack and the black test lead into the 'COM' jack.
4. Connect the test probes across the AC source or component.

3. Current Measurement (mA~ / A~)

IMPORTANT: Current measurements must always be performed in series with the circuit. Never connect the multimeter in parallel when measuring current, as this will short the circuit and damage the instrument.

1. Determine if you need to measure mA (milliamperes) or A (amperes) and select the corresponding position on the rotary switch ('mA~' or 'A~').
2. For mA measurements, insert the red test lead into the 'INPUT' jack. For A measurements (up to 10A), insert the red test lead into the '10A' jack. Always insert the black test lead into the 'COM' jack.
3. مداری را که می‌خواهید جریان را در آن اندازه‌گیری کنید، باز کنید.
4. Connect the multimeter in series with the circuit, so that the current flows through the multimeter.
5. If measuring AC current, press the 'SET' button to select AC mode.
