2. Safety Information

WARNING: To avoid electric shock or personal injury, read all safety information before using this product. Always adhere to local and national safety codes.

• This device complies with IEC 61010-1 safety standard and is rated CAT III 600V.
• Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and earth ground.
• Use caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
• Before use, inspect the meter, test leads, and accessories for any damage. Do not use if damaged.
• Ensure the function switch is in the correct position for the measurement being performed.
• Do not use the meter if the battery cover is not properly closed.
• When measuring current, ensure the circuit is de-energized before clamping the meter around the conductor.
• Always disconnect the test leads from the circuit before changing functions.

5. Setup and Battery Installation

5.1. Battery Installation

The MAYILON MY2600D is powered by two AAA batteries. To install or replace batteries:

1. Ensure the meter is turned off and disconnect any test leads.
2. Locate the battery compartment on the back of the meter.
3. Use a screwdriver to open the battery compartment cover.
4. Insert two AAA batteries, observing the correct polarity (+ and -) as indicated inside the compartment.
5. Replace the battery compartment cover and secure it with the screw.

A low battery indicator will appear on the display when the batteries need replacement.

6. Operating Instructions

Before making any measurements, ensure the test leads are properly connected and the function dial is set to the desired measurement type.

6.1. AC/DC Voltage Measurement

1. Insert the red test lead into the "INPUT" terminal and the black test lead into the "COM" terminal.
2. Rotate the function dial to the "V~" (AC Voltage) or "V-" (DC Voltage) position. The meter will automatically select AC or DC. If needed, press the "SEL" button to switch between AC and DC voltage.
3. Connect the test probes across the circuit or component to be measured.
4. Read the voltage value on the LCD display.

6.2. AC/DC Current Measurement (Clamp)

1. Rotate the function dial to the "A~" (AC Current) or "A-" (DC Current) position. Press "SEL" to switch between AC and DC current if necessary.
2. Open the clamp jaws by pressing the lever.
3. Enclose only one conductor of the circuit within the clamp jaws. Ensure the jaws are fully closed.
4. Read the current value on the LCD display.

6.3. Resistance Measurement

1. Insert the red test lead into the "INPUT" terminal and the black test lead into the "COM" terminal.
2. Rotate the function dial to the "Ω" (Resistance) position.
3. Connect the test probes across the component to be measured. Ensure the circuit is de-energized.
4. Read the resistance value on the LCD display.

6.4. Capacitance Measurement

1. Insert the red test lead into the "INPUT" terminal and the black test lead into the "COM" terminal.
2. Rotate the function dial to the "Capacitance" symbol position.
3. Discharge the capacitor before connecting the test probes. Connect the test probes across the capacitor.
4. Read the capacitance value on the LCD display.

6.5. Frequency Measurement

To measure frequency, rotate the function dial to the "Hz" position. Connect the test leads across the circuit where frequency needs to be measured. The display will show the frequency in Hertz (Hz).

6.6. Temperature Measurement

1. Insert the temperature probe into the "INPUT" and "COM" terminals, observing polarity if applicable.
2. Rotate the function dial to the "°C/°F" (Temperature) position.
3. Place the tip of the temperature probe on the object or in the environment whose temperature you wish to measure.
4. Read the temperature value on the LCD display. Press "SEL" to switch between Celsius and Fahrenheit.

6.7. Diode Test

1. Insert the red test lead into the "INPUT" terminal and the black test lead into the "COM" terminal.
2. Rotate the function dial to the "Diode" symbol position.
3. Connect the red probe to the anode and the black probe to the cathode of the diode.
4. Read the forward voltage drop on the display. Reverse the probes; the display should show "OL" (Overload) for a good diode.
