2. Safety Information

To ensure safe operation and service of the meter, please read this manual carefully before use. Failure to observe safety warnings can result in severe injury or death. Keep this manual for future reference.

• This meter is designed for indoor use only.
• Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and earth ground.
• Exercise extreme caution when working with voltages above 60V DC or 30V AC RMS. Such voltages pose a shock hazard.
• Before measuring current, ensure the circuit is de-energized and the clamp jaw is properly closed around a single conductor.
• Always disconnect the test leads from the circuit before changing functions.
• Do not operate the meter if it appears damaged or if the insulation is compromised.
• Replace the batteries immediately when the low battery indicator appears to ensure accurate readings.
• This meter is not a True-RMS meter. Consider this characteristic for specific applications.

4. Setup

4.1. Battery Installation

The EM201 requires two AAA batteries for operation. Batteries are not included with the device.

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

Note: When the low battery indicator appears on the display, replace the batteries promptly to ensure accurate measurements.

5. Operating Instructions

5.1. Power On/Off

• To turn the meter ON, press the red POWER button.
• To turn the meter OFF, press the red POWER button again.

5.2. Function Selection

Rotate the central green switch to select the desired measurement function. Ensure the switch clicks firmly into place for each selection.

5.3. AC Current Measurement (A)

1. Rotate the function switch to the desired AC Current range (2A, 20A, 200A, or 600A).
2. Press the trigger to open the clamp jaw.
3. Encircle a single conductor with the clamp jaw. Ensure the jaw is fully closed.
4. Read the AC current value on the LCD display.

Caution: Only clamp around a single conductor for accurate current measurement. Clamping around multiple conductors will result in an incorrect reading.

5.4. DC Voltage Measurement (V)

1. Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
2. Rotate the function switch to the DC Voltage range (600V).
3. Connect the test leads across the circuit or component to be measured.
4. Read the DC voltage value on the LCD display. Observe polarity.

5.5. AC Voltage Measurement (V)

1. Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
2. Rotate the function switch to the AC Voltage range (600V).
3. Connect the test leads across the circuit or component to be measured.
4. Read the AC voltage value on the LCD display.

5.6. Resistance Measurement (Ω)

1. Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
2. Rotate the function switch to the Resistance range (2KΩ or 2000KΩ).
3. Ensure the circuit or component to be measured is de-energized.
4. Connect the test leads across the component.
5. Read the resistance value on the LCD display.

Warning: Do not measure resistance on live circuits.

5.7. Diode Test

1. Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
2. Rotate the function switch to the Diode Test position (often 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. The display will show the forward voltage drop. Reverse the leads; the display should show "OL" (Open Line) for a good diode.

5.8. Continuity Buzzer

1. Insert the black test lead into the COM terminal and the red test lead into the VΩ terminal.
2. Rotate the function switch to the Continuity Test position (often indicated by a speaker or sound wave symbol).
3. Connect the test leads across the circuit or component.
4. If the resistance is below approximately 50Ω, the buzzer will sound, indicating continuity.

5.9. Data Hold Function

Press the HOLD button to freeze the current reading on the LCD display. Press it again to release the hold function and resume live readings.

5.10. Backlight and Torch

• Press the Torch button (light bulb symbol) to turn on the LCD backlight and the built-in flashlight.
• Press the Torch button again to turn them off.
