FEATURES

• Excellent Accuracy for LCR Measurement: This tool can measure capacitance, resistance, and inductance very closely, giving accurate readings for many uses.
• Digital Multimeter Design: Has a digital screen with a liquid crystal display (LCD) that shows data clearly and has a precision of 3 1/2 digits.
• Inductance Measurement: Accuracy up to ±(2%+5), which guarantees accurate readings of inductance values.
• Measurement of Capacitance: Accuracy up to ±(2%+5), which lets capacitance numbers be measured correctly.
• Diode Forward Voltage Drop: This shows the forward voltage drop of diodes, which is useful for checking components.
• DC Forward Voltage: This is a rough idea of the DC forward voltage with a current of 1mA, which helps when checking semiconductors.
• DC Reverse Voltage: This shows a close approximation of the reverse DC voltage, which makes it easier to test diodes.
• LCD Screen That Can Be Rotated: The LCD screen can be rotated so that it can be read easily from different angles. This makes measuring easier.
• Data Hold Function: This feature lets users stop numbers on the screen so that they can easily record and analyze data.
• Easy to Use: The small size and light weight make it easy to carry, and the auto-off function saves battery life.
• Low Power Indication: This lets you know when the battery power is low so that readings don’t end suddenly.
• ZERO ADJ for Capacitance: This feature lets users change the zero point for capacitance readings, which makes sure that the results are correct.
• Test Leads for the New Version: It comes with test loads, crocodile clips, and small alligator clips so you can join it in a number of different ways.
• Positive and Negative Connection: To make it easy to tell the difference between the two, the black pen is connected to the negative pole, and the red test lead is connected to the positive pole.
• Over-Range Display: Shows an over-range message on the LCD to let users know when the reading goes beyond the multimeter’s range.

SETUP GUIDE

• Installing the Battery: Carefully place one lithium-ion battery into the battery box, making sure that the polarity is right.
• Function Selection: To choose the measurement function (capacitance, resistance, or inductance), turn the dial.
• Connect to Device: Plug in the device being tested and connect the black test lead to the negative terminal and the red test lead to the positive terminal.
• Rotating LCD Display: Change the angle of the LCD display to get the best view while you’re measuring.
• When you press the “data hold” button, the measurement number on the screen will stay the same.
• Auto Power Off: To save battery life when the voltmeter is not in use, turn on the auto power-off function.
• Zero Adjustment for Capacitance: If you need to get correct results for capacitance measurements, you should do zero adjustment.
• Attaching Test Leads: To securely connect to the item being tested, use the test leads that came with it, crocodile clips, or small alligator clips.
• Safety Precautions: When working with electrical systems, follow the safety rules to avoid getting hurt or doing damage.
• Over-Range Display: Pay attention to the LCD’s “over-range” message to avoid taking wrong readings.
• Identification of Polarity: When connecting the test lines to the object being tested, make sure that the correct polarity is being used.
• Range of Measurements Choice: To get reliable results, choose the right measurement range on the multimeter.
• LCD Backlight: Change the backlight of the LCD as needed to see it clearly in different lighting situations.
• Function Testing: Do some sample readings on known parts to see how well the voltmeter works.

CARE & MAINTENANCE

• Storage: Keep the voltmeter somewhere dry and safe so that water or high temperatures don’t damage it.
• Cleaning: Use a soft, dry cloth to wipe down the voltmeter regularly to get rid of dust and other small things.
• Test Leads Check: Look for damage or signs of wear on the test leads and replace them if needed to get accurate readings.
• Maintenance for the battery: Change the battery when it’s dead and take it out of the voltmeter when not in use for a long time to stop leaks.
• Avoid Impact: Be careful when handling the voltmeter so that you don’t drop it or give it a mechanical shock.
• accuracy Check: Use a known reference measure to check the multimeter’s accuracy every so often.
• Safety Checks: Look over the voltmeter and test lines visually before each use to make sure they are in good shape.
• Polarity Check: To keep the device under test from getting damaged, double-check the polarity before connecting the test leads to it.
• Do Not Overload: To keep the multimeter from breaking, do not go over the highest recommended voltage or current.
• code Updates: If you can, update the multimeter’s code to get better features and fix bugs.
• Temperature Control: Do not put the voltmeter in very hot or very cold places, as this can damage its accuracy and performance.
• Probe Protection: Keep the test leads in the right way to keep the wires and connections from getting damaged.
• Be Careful: Do not bend or twist the test leads too much to keep the wires inside from getting damaged.
• Maintenance Checks: Make sure the voltmeter works right and is safe by doing maintenance checks on it every so often.
