Common questions about manuals, registration, and support for this brand.
For analog models like the S471 or T88A, locate the mechanical zero adjuster screw on the face of the dial. With the meter off/disconnected, gently turn the screw until the pointer aligns exactly with the zero mark on the left side of the scale.
NCV stands for Non-Contact Voltage detection. This feature allows you to identify the presence of AC voltage without direct metallic contact, typically alerting you via an audible buzzer or flashing LED when brought near a live wire.
Many NJTY handheld instruments, such as the T21L or T6005, operate on standard AAA 1.5V batteries or rechargeable lithium batteries (e.g., 18650 for some testers). Always verify the specific requirement in your model's battery compartment.
Standard clamp meters often only measure AC current through the jaws. However, advanced NJTY models may support DC current measurement via the clamp. For most models, DC current can be measured by connecting the test leads in series with the circuit.
