Overview

Electrical testers can measure the presence of voltage and are suitable for both AC and DC voltages. As a multimeter, in addition to accurately measuring voltage, it can also measure other data. The automatic detection function of this instrument is applicable to almost all electrical fields and does not require any switching.

Product Details

The instrument automatically detects and measures parameters, with simple and reliable operation
Electrical standard compliant with DIN EN 61243-3:2010
Having interchangeable measurement ports
Suitable for almost all daily electrical measurement tasks

The testo755-1 current and voltage on/off tester is a voltage tester with current measurement function, which can perform voltage or power-off tests on circuits or electrical systems, as well as measure current or current consumption and system on/off tests. The testo755-1 voltage tester automatically detects and selects electrical measurement parameters, and you only need to start measuring without any other operations.

The measurement port that can be quickly and easily exchanged is easy to use and maintain. Once the instrument is damaged, you only need to replace the spare parts. The lighting function can assist in measuring in dark environments.

The testo755-1 current and voltage on-off tester is a powerful tool that meets your daily electrical measurement needs

product description

The testo 755-1 is the industry's first current/voltage measuring instrument. Compliant with the latest measurement standards and equipped with current detection function. When in use, the instrument automatically detects measurement parameters to match appropriate settings, eliminating the need for manual selection or switching operations.

Users can easily replace the measuring probe, so there is no need to replace the entire instrument in case of damage. Practical design: Integrated lighting, convenient for measuring dark measurement points.

Measuring current: precautions

When using the Detu tester to test current, the voltage tester can directly detect dangerous voltages. In addition, due to the simple design of the tester, the probability of misoperation is very low. The current tester will never have safety issues, and its design ensures that any risks during operation are low and there will be no electric shock or arc faults. CAT IV instruments are used for measuring 600 V, while CAT III instruments are used for measuring 1000 V, ensuring user safety

It is recommended that you always operate the voltage tester with both hands to avoid accidental contact with live test electrodes. In addition, the tester complies with strict safety standards and comes with T Ü V, CSA, and CE certification marks.

Before testing the voltage, a functional test is required. To do this, place the tester on a known current source and check if the display is correct. During this period and in actual current testing, some components will be used:

LED is used for illumination of measurement points
digital display
