Battery Replacement
1. Turn power OFF and release the end cap latch from the pocket clip and slide out the battery compartment (3).
2. Replace the four LR44 batteries and replace the battery compartment.
Never dispose of used batteries or rechargeable batteries in household waste.
As consumers, users are legally required to take used batteries to appropriate collection sites, the
retail store where the batteries were purchased, or wherever batteries are sold.
Disposal:
Do not dispose of this instrument in household waste. The user is obligated to take end-of-
life devices to a designated collection point for the disposal of electrical and electronic equipment.
Operation
WARNING: Risk of Electrocution. Before use, always test the Detector on a known live circuit to verify
proper operation.
NOTE on RF Interference: RF signals in close proximity to the detector may cause the voltage light and beeper to
latch into a constant tone and light indication. Wait until the RF signal has disappeared before proceeding with
voltage detection.
1. Turn the On/Off-Sensitivity switch (2) clockwise to turn the unit on.
2. Set the Sensitivity adjustment (2) to the high (counterclockwise) position
3. If the detector begins to beep/flash (1), slowly reduce the sensitivity (clockwise) until the beep stops.
4. Move the detector voltage sensor (1) near the conductor until the tip flashes and beeper sounds.
5. Slowly adjust the sensitivity (2) and reduce the distance between the sensor and conductor to pinpoint and identify
the conductor.

Overview

1. Function Description
2. Important Technical Specifications
3. Usage Features
4. Maintenance Features

The Extech Model DV30 is an AC Voltage Detector designed for non-contact voltage detection, offering adjustable sensitivity for precise identification of live conductors. This device is intended for indoor use and is categorized under IEC 1010, Category III 600V, indicating its suitability for use in fixed installations such as distribution boards, circuit breakers, and wiring systems.

Function Description:

The primary function of the DV30 is to detect the presence of AC voltage in conductors without direct contact. It utilizes a voltage sensor at its tip that flashes and beeps when AC voltage is detected. The adjustable sensitivity feature allows users to fine-tune the detection range, enabling them to pinpoint specific conductors or identify the general presence of voltage. The device is powered by four LR44 batteries, which are housed in a compartment accessible by releasing an end cap latch.

Important Technical Specifications:

• Voltage Sensitivity: The detector can sense AC voltages ranging from 12V to 600VAC, operating within a frequency range of 50 to 500Hz. This wide range makes it versatile for various electrical applications.
• Operating Temperature/Humidity: It operates effectively in temperatures from -10°C to 50°C (14 to 122°F) and relative humidity below 80%.
• Storage Temperature: The device can be stored in temperatures from -20°C to 60°C (-4 to 140°F) with relative humidity below 80%.
• Operating Altitude: The maximum operating altitude is 7000 ft. (2000 meters).
• Dimensions/Weight: Compact and lightweight, the DV30 measures 155x28x25mm (6.3x0.75x1") and weighs 42g (2oz), making it easy to carry and handle.
• Safety Rating: It holds an IEC 1010, Category III 600V rating, signifying its compliance with safety standards for electrical measurements in specific environments.
• Power Source: Requires four LR44 batteries for operation.

Usage Features:

• Adjustable Sensitivity: The On/Off-Sensitivity switch (2) allows users to turn the unit on and adjust its sensitivity. Turning it counterclockwise sets it to high sensitivity, while turning it clockwise reduces sensitivity. This feature is crucial for accurate pinpointing of conductors and avoiding false positives.
• Visual and Audible Indicators: The detector provides both visual (flashing tip) and audible (beeper) indications when voltage is detected, ensuring clear feedback to the user.
• Easy Operation: To use, the device is turned on, sensitivity is initially set to high, and then adjusted until the beep stops if it initially sounds. The sensor is then moved near the conductor, and sensitivity is further adjusted to pinpoint the conductor.
• Safety Precautions: The manual emphasizes critical safety guidelines, including reading the guide before use, ensuring covers and battery doors are secure, inspecting for damage, and removing batteries for long-term storage. It also highlights the importance of testing the detector on a known live circuit before use to verify proper operation.
• RF Interference Note: Users are advised that RF signals in close proximity may cause the voltage light and beeper to latch into a constant tone and light indication. It is recommended to wait until the RF signal has disappeared before proceeding with voltage detection.
• International Safety Symbols: The device and manual incorporate international safety symbols, including a warning triangle for referring to the user's guide, a lightning bolt for hazardous voltages, and a double insulation symbol.

Maintenance Features:

• Battery Replacement: The battery compartment (3) is easily accessible by releasing the end cap latch from the pocket clip. Users can slide out the compartment to replace the four LR44 batteries.
• Battery Disposal: The manual provides clear instructions for the environmentally responsible disposal of used batteries, emphasizing that they should not be disposed of in household waste but taken to appropriate collection sites.
• Device Disposal: Similarly, the manual outlines the user's obligation to dispose of the instrument at a designated collection point for electrical and electronic equipment at the end of its life, rather than in household waste.
• Warranty and Support: Teledyne FLIR LLC provides a two-year warranty for the Extech brand instrument, with a six-month limited warranty for sensors and cables. Calibration and repair services are also offered, with NIST traceable calibration available for most products. Contact information for customer support, calibration, repair, and technical support is provided. Annual calibrations are recommended to verify performance and accuracy.
