Greenlee HVA-2000 High Voltage Digital Ammeter User Manual

1. Introduction

The Greenlee HVA-2000 is a high voltage digital ammeter designed for precise AC current measurements. This device allows for quick and easy ampere measurements on conductors up to 500kV. Its large, bright, 4-digit LED display ensures clear readability of current values, even from a distance when used with telescoping hotsticks. The HVA-2000 is engineered for ease of use and portability, making it suitable for live line operations.

Key features include 1% accuracy and the ability to store the last four readings, facilitating real-time monitoring or post-measurement analysis.

2. Safety Information

Always adhere to local safety regulations and company policies when working with high voltage equipment. This device is intended for use by qualified personnel only.

• Use with Hotstick: The HVA-2000 requires a hotstick for safe operation. The hotstick is sold separately and is essential for maintaining a safe distance from high voltage conductors.
• Personal Protective Equipment (PPE): Always wear appropriate PPE, including insulated gloves, safety glasses, and flame-resistant clothing, when performing measurements on live circuits.
• Environmental Conditions: Do not use the ammeter in wet conditions or in environments where explosive gases or dust may be present.
• Inspection: Before each use, inspect the HVA-2000 and the hotstick for any signs of damage. Do not use if damaged.

3. Setup

3.1 Unpacking and Inspection

Carefully remove the HVA-2000 and its accessories from the nylon carrying case. Verify that all components are present and undamaged. The standard package includes the HVA-2000 unit and a nylon carrying case. A 9V battery is required for operation and is not included with the unit.

3.2 Battery Installation

1. Locate the battery compartment on the HVA-2000 unit.
2. Open the battery compartment cover.
3. Insert one 9V battery, ensuring correct polarity (+/-).
4. Close the battery compartment cover securely.

3.3 Attaching to a Hotstick

The HVA-2000 is designed to be attached to a standard telescoping hotstick (sold separately). Ensure the hotstick is clean, dry, and rated for the voltage level of the conductors being measured.

1. Align the mounting mechanism of the HVA-2000 with the end of the hotstick.
2. Securely fasten the ammeter to the hotstick according to the hotstick manufacturer's instructions. Ensure there is no wobble or looseness.

4. Operating Instructions

4.1 Powering On/Off

• To power on the HVA-2000, press the "ON" button located on the unit. The 4-digit LED display will illuminate.
• To power off, press the "OFF" button. The unit may also feature an auto-off function to conserve battery life.

4.2 Taking Measurements

The HVA-2000 is designed to measure AC current on conductors up to 500kV and up to 2000 amps, within a frequency range of 25 to 500 Hz.

1. Ensure the HVA-2000 is securely attached to a hotstick.
2. Extend the hotstick to safely reach the conductor.
3. Carefully position the ammeter's jaws around the conductor. Ensure the conductor is fully enclosed within the jaws for accurate measurement.
4. Read the current value displayed on the large LED screen. The display is designed for visibility from a distance.
5. Once the measurement is complete, carefully remove the ammeter from the conductor using the hotstick.

4.3 Stored Readings Function

The HVA-2000 can store the last 4 readings. This feature allows for quick recall of recent measurements without needing to re-measure.

• Refer to the specific button or sequence on the device (if available, not detailed in provided data) to cycle through the stored readings.
• This function is particularly useful for comparing consecutive measurements or reviewing data after live line operations.

5. Maintenance

5.1 Cleaning

Keep the HVA-2000 clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.

5.2 Storage

When not in use, store the HVA-2000 in its provided nylon carrying case in a cool, dry place, away from direct sunlight and extreme temperatures. Remove the 9V battery if the unit will not be used for an extended period to prevent battery leakage.

5.3 Battery Replacement

Replace the 9V battery when the low battery indicator appears on the display or if the unit fails to power on. Follow the battery installation steps outlined in Section 3.2.
