Installation / Setup

The installation and setup of the Heathkit Model AV-2 A.C. Voltmeter involve several key steps. Begin by unpacking the kit carefully and checking each part against the parts list. It is recommended to read the manual completely before starting construction to become familiar with the procedure. The assembly starts with mounting the tube sockets, calibration control, selenium rectifier, terminal strips, and rubber grommets as shown in the provided figures. Wiring should be completed according to the pictorial wiring diagram, ensuring that leads are cut to the proper length for a neat appearance and to avoid erratic operation. Proper polarity must be observed for components like electrolytic condensers and selenium rectifiers. Acid core solder or pastes should not be used, as they void guarantees and service agreements. After wiring, precision resistors are mounted on the range selector switch, followed by the range switch on the panel, and then the pilot light and input terminal assemblies. The meter and power switch should not be mounted until the panel is attached to the chassis.

Heathkit AV-2 AC Voltmeter Overview

The Heathkit AV-2 AC Voltmeter is a precision instrument designed to measure alternating current (AC) voltage in electronic circuits and electrical systems. Ideal for hobbyists, technicians, and engineers, this device provides accurate voltage readings, enabling effective troubleshooting and maintenance of AC-powered equipment. Its compact design and user-friendly interface make it a reliable tool for both field and laboratory use.

Main Features and Specifications

• Measurement Range: 0 to 600 volts AC
• Accuracy: ±2% of full scale
• Input Impedance: High impedance for minimal circuit loading
• Analog Display with Clear Scale Markings
• Robust Construction for Durability
• Battery Powered for Portability
• Includes Schematics for Easy Repair and Calibration

Basic Usage and Operation Tips

Before use, ensure the device is properly calibrated and the battery is fully charged. Connect the test leads securely to the circuit points where voltage measurement is required. Always start measuring at the highest voltage range to prevent damage to the meter. Read the analog needle position carefully against the scale to determine the voltage. After use, turn off the device to conserve battery life.

Troubleshooting and Maintenance

If the meter displays erratic readings or fails to respond, first check the battery condition and replace if necessary. Inspect test leads for any damage or loose connections. Refer to the included schematics for detailed circuit analysis and repair guidance. Regularly clean the meter’s exterior and keep the analog needle mechanism free from dust to maintain accuracy. Avoid exposure to extreme temperatures or moisture.
