Terminals

The multimeter features input jacks for various measurements. Jack indication lights guide the user to insert test leads correctly.

• 10A Jack: Input terminal for measuring AC/DC current up to 10A.
• mA Jack: Input terminal for measuring AC/DC current up to 600mA.
• COM Jack: Common (return) terminal for all measurements.
• Live/DC/AC Voltage, V, Hz, %C/F Jack: Input terminal for measuring voltage, continuity, resistance, capacitance, frequency, and testing diodes.

Making Measurements

When connecting test leads, connect the common (COM) lead first, then the live lead. When disconnecting, remove the live lead first, then the common lead.

Warnings

• Do not measure voltages higher than 1000V DC or 750V AC.
• Exercise caution when measuring high voltages.
• Test the meter with a known voltage or current before use to confirm proper operation.

SMART (AUTO) Measurement Mode

The meter defaults to SMART mode, which automatically detects and selects the range for DC voltage, AC voltage, resistance, and continuity measurements.

1. Turn on the meter by pressing and holding the power button (⏻) for approximately 2 seconds. The screen will display 'Auto' and the pointer will move, indicating SMART mode.
2. Insert the red probe into the appropriate jack (e.g., VΩHz%°C/F) and the black probe into the 'COM' jack.
3. Touch the test leads together. A beep and indicator light confirm normal operation (used for continuity check).

Measurement in SMART Mode:

• Voltage AC/DC: Connect the test leads across the circuit. The meter automatically detects AC or DC voltage. When measuring AC voltage, the frequency is displayed. When measuring DC voltage, the ambient temperature is displayed.
• Resistance: Connect the test leads across the resistance (in parallel). If the resistance is less than 50Ω, the meter will beep and the indicator light will turn on.

Note:

• Minimum measurable voltage in SMART mode: AC: 0.5V, DC: 0.8V.

MANUAL Measurement Mode

Press the 'AUTO FUNC' button to switch from SMART mode to MANUAL mode. Press the button again to cycle through the available measurement functions.

AC/DC Voltage Measurement

1. Ensure the meter is on and test leads are connected correctly.
2. Press 'AUTO FUNC' until the '― V' symbol and 'V' signal are displayed for DC voltage measurement.
3. Press 'SEL' to switch to AC voltage measurement, indicated by '∼ V' and 'V' signals.

Note:

• Frequency is displayed during AC voltage measurement.
• Ambient temperature is displayed during DC voltage measurement.
• Do not use AC function for DC voltage and vice versa.
• Do not measure voltages exceeding 1000V DC or 750V AC.

Resistance Measurement

1. Ensure the meter is on and test leads are connected correctly.
2. Press 'AUTO FUNC' until the 'Ω' symbol is displayed for resistance measurement.

Note:

• Do not change resistance while measuring.
• Avoid measuring parallel circuits as it affects accuracy.
• Do not directly measure the internal resistance of instruments like micrometers, galvanometers, or batteries.

Continuity Test

1. Ensure the meter is on and test leads are connected correctly.
2. Press 'AUTO FUNC' to select the continuity measurement mode (indicated by a sound symbol ∼).
3. Connect the test leads to the circuit. If the resistance is less than 50Ω and the circuit is live, the buzzer will sound, and the indicator light will illuminate. The measured resistance value will be displayed.

Diode Test

1. Ensure the meter is on and test leads are connected correctly.
2. Press 'AUTO FUNC' to select the diode test mode (indicated by a diode symbol ⌫).
3. Connect the red test lead to the anode and the black test lead to the cathode of the diode.
4. If connected in reverse polarity, '[ ]' will be displayed. A forward voltage drop will be displayed for a good diode.

Capacitance Measurement

1. Ensure the meter is on and test leads are connected correctly.
2. Press 'AUTO FUNC' to select the capacitance measurement mode (indicated by 'nF' or '⌂' symbol).

Note:

• Discharge the capacitor before and after measurement to avoid damage and safety hazards.
• A significantly different reading from the marked value indicates a damaged capacitor.
• Large capacitance values may require a longer time for readings to stabilize.

AC/DC mV Voltage Measurement
