3. Setup and Assembly

3.1 Battery Installation

1. Locate the battery compartment on the DVM-80UVM voltmeter unit.
2. Open the battery case cover. No tools are required for this step.
3. Insert a fresh 9V lithium or alkaline battery, ensuring correct polarity.
4. Close the battery case cover securely.

3.2 Probe Connection

1. Identify the appropriate probes for your application (overhead hook probes, underground bushing probes, or add-on resistor sticks).
2. Connect the probes firmly to the DVM-80UVM voltmeter unit. Ensure a secure electrical and mechanical connection.
3. For measurements above 15kV, attach the add-on resistor sticks as instructed in the specific application guide.

4. Operating Instructions

4.1 Powering On and Self-Test

Press the power button to turn on the DVM-80UVM. The unit will perform a brief self-test, and the display will illuminate, showing '0.00' or a similar ready state.

4.2 Voltage Measurement

1. Ensure the correct probes are attached for the voltage range and application.
2. Carefully apply the probes to the circuit or conductor to be measured.
3. Read the voltage value displayed on the 3.5 digit display. The unit automatically ranges for optimal reading.

4.3 Peak Hold Feature

To activate the Peak Hold feature, press the dedicated Peak Hold button. The display will then show and hold the highest voltage detected during the measurement period. Press the button again to exit Peak Hold mode.

4.4 Test Point Feature

When measuring voltage on elbow test points, the DVM-80UVM will automatically detect and display the system voltage, simplifying the measurement process for these specific applications.

4.5 Cable Fault Testing

Utilize the included Cable Fault Tester in conjunction with the DVM-80UVM to perform underground cable fault testing. Refer to the specific instructions provided with the Cable Fault Tester for detailed procedures.

4.6 Voltmeter Proof Testing

Before and after each use, it is recommended to test the voltmeter with the Voltmeter Proof Tester. This ensures the accuracy and proper functioning of the DVM-80UVM. Connect the voltmeter to the proof tester and verify the reading as per the proof tester's instructions.

5. Maintenance

5.1 Cleaning

Regularly clean the exterior of the voltmeter and probes with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure all components are dry before storage or next use.

5.2 Battery Replacement

Replace the 9V battery when the low battery indicator appears on the display or if the unit fails to power on. Always use a fresh lithium or alkaline battery for optimal performance.

5.3 Storage

Store the DVM-80UVK kit in its provided soft-sided carrying bag in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure all probes and accessories are properly secured within the bag.
