How to use
Before use, visually inspect the tester and probe for damage. To measure, place the probe tip in contact with the conductor or terminal to be tested while observing the indicator (visual or acoustic, depending on the unit). Ensure the tester body or reference contact is held as instructed by the manufacturer to complete the circuit if required. Use the tool to determine presence or absence of voltage in the specified 125–250 V range, and avoid using it on unknown high-voltage systems or where insulation is compromised.
Usage recommendations
Use the tester only on circuits within its specified voltage range and follow standard electrical safety practices: disconnect power where possible, wear appropriate protective equipment, and verify the tester operation on a known live source before and after testing. Store the device in a dry, dust-free environment and replace the tester if probe insulation or housing shows signs of damage.
