Customer Questions & Answers

What are the dimensions and main material of the tester, and what is included in the box?

The tester measures approximately 150 mm in length and is made from black ABS plastic. The package includes only the tester, without the AAA (1.5V) battery, which the user must purchase separately.

Is any calibration or periodic maintenance needed to ensure accurate readings?

How do I read the LED indicator?
