1. Introduction
Thank you for choosing the ETURBEV DT3266L Digital Clamp Meter Multimeter. This device is a portable, professional measuring instrument designed for testing AC current, AC/DC voltage, resistance, and continuity. It is suitable for electricians, hobbyists, and general household use. Please read this manual thoroughly before operation to ensure safe and correct usage.
2. Safety Information
To ensure safe operation and service of the meter, follow these safety precautions:
- Always disconnect the test leads from the circuit before changing functions.
- Do not apply voltage or current that exceeds the maximum rated input values.
- Exercise extreme caution when working with voltages above 60V DC or 30V AC RMS, as these pose a shock hazard.
- Inspect test leads for damaged insulation or exposed metal before use. Replace if damaged.
- Do not operate the meter if it appears damaged or if the case is open.
- Ensure the battery cover is securely closed before operation.
- Use the correct terminals, function, and range for your measurements.
3. Product Overview
The ETURBEV DT3266L is a compact digital clamp meter featuring a clear LCD display and a rotary function switch for easy selection of measurement modes.

Key Components:
- Clamp Jaw: Used for non-contact AC current measurement.
- Function Rotary Switch: Selects measurement functions and ranges.
- LCD Display: Shows measurement readings and indicators.
- Data Hold Button (HOLD): Freezes the current display reading.
- Backlight Button (LIGHT): Activates or deactivates the display backlight.
- Input Jacks: For connecting test leads (COM for common/negative, VΩmA for positive).
4. Setup
4.1 Battery Installation
The meter requires two AAA batteries (not included) for operation. To install or replace batteries:
- Ensure the meter is turned OFF.
- Locate the battery compartment on the back of the meter.
- Unscrew the battery compartment cover and remove it.
- Insert two AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
- Replace the battery cover and secure it with the screw.
4.2 Connecting Test Leads
For voltage, resistance, and continuity measurements, connect the test leads:
- Insert the black test lead into the 'COM' (common) input jack.
- Insert the red test lead into the 'VΩmA' input jack.

5. Operating Instructions
5.1 AC Current Measurement (Clamp Jaw)
To measure AC current:
- Turn the rotary switch to the desired AC Current range (e.g., 20A, 200A, 600A).
- Open the clamp jaw by pressing the trigger.
- Enclose only one conductor of the circuit to be measured within the clamp jaw. Ensure the jaw is fully closed.
- Read the AC current value on the LCD display.
5.2 AC/DC Voltage Measurement
To measure AC or DC voltage:
- Connect the test leads as described in Section 4.2.
- Turn the rotary switch to the desired ACV (V~) or DCV (V-) range (e.g., 600V).
- Connect the test leads in parallel to the circuit or component you wish to measure.
- Read the voltage value on the LCD display.
5.3 Resistance Measurement
To measure resistance:
- Connect the test leads as described in Section 4.2.
- Turn the rotary switch to the desired Resistance range (e.g., 2kΩ, 200kΩ).
- Ensure the circuit or component under test is de-energized.
- Connect the test leads across the component.
- Read the resistance value on the LCD display.
5.4 Data Hold Function
Press the 'HOLD' button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.
5.5 Backlight Function
Press the 'LIGHT' button to turn on the display backlight for better visibility in dimly lit environments. Press it again to turn off the backlight.
6. Maintenance
6.1 Cleaning
Wipe the meter's case with a damp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals free of dirt and moisture.
6.2 Battery Replacement
When the battery indicator appears on the display, replace the batteries as described in Section 4.1. Remove batteries if the meter is not used for an extended period to prevent leakage.
6.3 Storage
Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
- No Display: Check battery installation and charge. Replace batteries if necessary.
- Inaccurate Readings: Ensure correct function and range are selected. Check test lead connections. Verify the circuit is de-energized for resistance measurements.
- 'OL' or '1' on Display: Indicates over-range. Select a higher range or check if the circuit is open (for resistance).
- No AC Current Reading: Ensure only one conductor is enclosed within the clamp jaw.
