2. સલામતી માહિતી

Always adhere to safety precautions when using electrical testing equipment. Failure to do so may result in electric shock, injury, or damage to the multimeter or equipment under test.

• ઓવરલોડ પ્રોટેક્શન: The multimeter is equipped with overload protection. When the input voltage is below 250V, the device automatically prevents burnout.
• Fuse Disconnect Function: In case of excessive current, the internal fuses will blow to protect the multimeter's internal circuitry. If a fuse blows, the screen will display "FUSE" and an alarm will sound.
• Wrong Polarity Alarm: If the test leads are connected to ports that do not match the selected measurement function (gear position), the screen will display "LEAD" and emit an audible beep. Correct the lead connection immediately.
• Ensure the multimeter's safety class (IEC61010 CAT.600V CAT IV, 1000V CAT.III) is appropriate for the measurement task.
• વોલ્યુમ માપવાનો પ્રયાસ કરશો નહીંtagનિર્દિષ્ટ મહત્તમ મર્યાદા કરતાં વધુ પ્રવાહો અથવા પ્રવાહો.
• Inspect test leads for damage before each use. Replace damaged leads immediately.

5. ઓપરેટિંગ સૂચનાઓ

5.1 પાવર ચાલુ/બંધ

To power on the multimeter, rotate the gear rotating disc from the "OFF" position to any desired measurement function. To power off, rotate the disc back to the "OFF" position.

5.2 Automatic and Manual Ranging

Figure 5.1: Rotary switch indicating Automatic and Manual Ranging sections.

• Automatic Range Function: When the rotary switch is set to the "AUTOMATIC RANGE" section, the multimeter automatically selects the appropriate measurement range for AC/DC voltage, resistance, capacitance, frequency, on/off (continuity), and diode tests. This simplifies operation.
• Manual Range Function: When the rotary switch is set to the "MANUAL RANGE" section, you can manually select specific ranges for NCV, Live wire identification, AC/DC voltage, AC/DC current, temperature, and resistance measurements. This provides greater control for experienced users.

5.3 Specific Measurements

Follow these general steps for most measurements:

1. Connect test leads correctly as described in Section 4.2.
2. Rotate the gear rotating disc to the desired measurement function.
3. If multiple functions are available at one position (e.g., AC/DC voltage), press the "SEL." button to toggle between them.
4. Apply the test leads to the circuit or component under test.
5. Read the measurement value on the VA screen.

Store the multimeter in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries.

7. મુશ્કેલીનિવારણ

• Display shows "LEAD" and beeps: This indicates incorrect test lead connection for the selected function. Reconnect the test leads to the appropriate input jacks.
• ડિસ્પ્લે "OL" બતાવે છે: This indicates an overload condition, meaning the measured value exceeds the selected range or the multimeter's maximum capacity. Switch to a higher range (if in manual mode) or ensure the measurement is within the device's limits.
• Multimeter does not power on: બેટરી ઇન્સ્ટોલેશન તપાસો અને ખાતરી કરો કે બેટરી ખાલી નથી થઈ ગઈ. જો જરૂરી હોય તો બદલો.
