General
Acoustic signal	ab 50 V
Pass-through test
Self-test

The TX01 voltage tester from Metrix is a compact measuring device for visual and acoustic voltage testing as well as continuity testing in electrical installations. The device is suitable for use in electrical installation, maintenance and testing of circuits up to 690 V AC/DC. It features integrated cable storage and a removable test probe, making it compact and safe to transport. The functions include voltage detection, phase marking, polarity testing, continuity test, resistance measurement and a self-test for battery and device.

Applications

The voltage tester is used in electrical engineering to check for the presence of voltage in wires, sockets, switches and other electrical components. It is particularly useful for testing live and neutral conductors, with phase marking also possible using one hand. Polarity testing enables identification of positive and negative poles, which is important when working with DC systems. Continuity testing is used to check the electrical conductivity of cables, switches or other components.

Functions and Equipment in Detail

The device features seven LEDs that light up differently depending on the voltage level. Voltage detection is performed in the range of 12 to 690 V AC/DC, with an acoustic signal triggered at voltages above 50 V. Polarity testing is indicated by separate LEDs for positive and negative. The continuity test detects resistances below 2 kΩ and also enables a diode test. Resistance measurement is performed in the range of 2 kΩ to 300 kΩ, with three LEDs visually indicating the measured values. A self-test checks the function of the 9 V battery as well as the entire tester, including cable, electronics and LEDs.

Technology Explained Simply

The technology of the TX01 is based on a combination of optical and acoustic signalling. The LEDs light up depending on the measured voltage, with the number of lit LEDs indicating the voltage level. The acoustic signal serves as an additional warning, especially at high voltages. The integrated cable storage ensures that the cable is neatly stored and not damaged. The removable test probe allows for flexible handling and facilitates cleaning or replacement. The voltage protection class of 1000 V protects the device against overvoltage.

Compatibility and Accessories

The device is compatible with a red test probe 600 V CAT IV, available as an accessory. This test probe is suitable for use in high-voltage environments and complies with safety category CAT IV. Combining it with this test probe extends the device's application possibilities in safety-critical installations.

Mounting and Installation

The TX01 voltage tester is not mounted, but held directly in hand and connected to the conductors to be tested. Testing is performed by touching the test probes to the conductors. The integrated cable storage ensures that the cable is neatly stored and does not get in the way. Testing can also be performed with one hand, which facilitates handling in confined spaces.

Advantages in Operation

Operation of the device is simple and intuitive. The visual and acoustic signalling enables quick and safe testing. The self-test ensures the device is always functional. The integrated cable storage and removable test probe increase safety and comfort during use. Electrical safety according to IEC 61010 600 V CAT III ensures suitability for use in industrial and commercial installations.
