Frequently Asked Questions (FAQ)
How does non-contact voltage detection work?
The non-contact tester works on the principle of detecting the electrostatic field created by alternating current (AC) voltage around a conductor. When you bring the tip of the tester close to a wire or socket, the device detects this field and warns you of the presence of voltage with an audible signal (beep) and colored LED indicators.
Can I also detect direct current (DC) voltage with this tester?
No, this specific Deli EDL8011 model is designed exclusively for detecting alternating current (AC) voltage in the range of 12V to 1000V. It is not suitable for measuring direct current (DC) voltage, such as car batteries or conventional batteries.
What do the different colors on the indicator mean?
The tester uses three colors to indicate the level of detected voltage: green indicates low voltage, yellow indicates medium voltage, and red warns you of high voltage. This allows you to quickly and intuitively assess the condition of the wiring.

Answers to frequently asked questions

Does the tester detect voltage without direct contact with the conductor?

Yes, the non-contact tester works by detecting the presence of voltage when approaching an electrical conductor, so it is not necessary to directly touch the wire.

What class of users typically uses such a tester?

It is primarily intended for a wider group of consumers who need a quick voltage check at home, in the workshop or in the field, and for those who prioritize safety when making basic repairs.

How do I see when the tester has detected voltage?

When voltage is detected, the tester warns with an LED light and often an audible signal, allowing you to clearly see the result even in poor lighting conditions.

Is this tester suitable for use in a humid environment?

The model is intended for normal home and workshop use; extra caution is required when working in a humid environment, as basic testers often do not have increased protection against moisture.

What to do if the tester is not working properly?

First, check that the batteries are properly inserted and properly charged; if the problem is not with the battery, we recommend having the tester inspected by a power tool specialist.
