Weighing only 0.2 kg, this device combines advanced functionality with ergonomic design, making it an indispensable companion on any job site.

Key Features at a Glance

• Dual Voltage Measurement: Detects both AC and DC voltages up to 690 V.
• Continuity Testing: Quickly verifies circuit integrity with audible and visual alerts.
• Phase Rotation Detection: Determines the correct phase sequence in three‑phase systems.
• LCD Digital Display: Clear, backlit readout for accurate readings even in low light.
• Built‑in Torch: Integrated LED lamp provides illumination without a separate flashlight.
• Safe Isolation (GS38+ Case): Robust construction protects users from accidental contact and environmental hazards.

Design & Build Quality

The DL6790’s lightweight profile is achieved through the use of high‑strength polymers and a streamlined chassis. Despite its small size, the tester features a durable GS38+ case, rated for industrial environments and resistant to impact, dust, and moisture. The ergonomic grip ensures comfortable handling during prolonged use.

LCD Digital Display & User Interface

The backlit LCD provides real‑time voltage readings with high resolution. Its intuitive interface allows users to switch between AC, DC, continuity, and phase rotation modes with a single button press. The display also shows error codes and battery status, ensuring that the tester is always ready for action.

Voltage Measurement Capabilities

The DL6790 can measure voltages from 0 V up to 690 V in both AC and DC modes. This wide range covers most residential, commercial, and industrial applications. The device automatically selects the appropriate measurement mode based on input voltage, reducing user error.

Continuity Testing

With a simple touch of the probe tips, the tester emits a clear audible tone and visual indicator when continuity is confirmed. This feature is essential for troubleshooting wiring faults, checking switches, and verifying circuit connections quickly and accurately.

Phase Rotation Detection

The phase rotation test mode identifies the correct sequence (ABC or ACB) in three‑phase systems. By connecting the probes to each phase, the tester displays the rotation order on the LCD, helping technicians avoid costly mistakes during installation or maintenance of motor drives and power distribution equipment.

Built‑in Torch

The integrated LED flashlight is powered by the same battery that runs the tester, providing a convenient light source for working in dark spaces without needing an additional tool. The torch can be activated with a dedicated button, ensuring quick illumination when needed.

Safe Isolation & Compliance

Constructed to meet stringent safety standards, the DL6790’s GS38+ case offers isolation from high‑voltage sources, protecting users from accidental shocks. Its robust design also resists environmental factors such as dust and moisture, making it suitable for outdoor or industrial settings.

Battery Life & Power Management

The tester operates on a standard rechargeable battery pack that delivers extended usage between charges. The device includes power‑saving features: automatic shutdown after a period of inactivity and low‑power standby mode, ensuring efficient energy consumption during long work sessions.

Applications Across Industries

• Electrical Installation: Verify voltage levels, continuity, and phase rotation in new wiring projects.
• Maintenance & Troubleshooting: Quickly diagnose faults in existing circuits or equipment.
• HVAC & Motor Systems: Confirm correct phase sequence for motor operation.
• Renewable Energy: Test solar panel outputs and inverter connections.
• Education & Training: Serve as a teaching aid in electrical engineering courses.
