What is the job of a test technician for electrical tests according to DGUV regulation 3?

What is the job of a test engineer for electrical tests according to DGUV regulation 3?

The daily work of a test technician in the test service according to DGUV regulation 3 is varied and characterized by a feeling of responsibility. The electrical test differs significantly from the activity in electrical installation. When installing electrical systems, there is often a construction site environment with corresponding noise and dirt. The activity sometimes requires a lot of effort with repetitive movements that can have a negative effect on joints.

In the inspection service according to DGUV regulation 3, however, the inspection technician has the responsible role of a security controller. In the course of the electrical test according to DGUV regulation 3, he controls the work of the installer and regularly monitors the suitability of the electrical work equipment and systems during their entire service life.

The working environment is usually clean and communication with colleagues and customers takes place on an equal footing. He is on the move, without exhausting work steps and alternates between checking and documenting. The day-to-day work is very independent and organized, with a team of back office colleagues who support him and give him strength.

Serious service providers for electrical tests according to DGUV regulation 3 only employ trained, highly qualified test technicians or train them specifically for this themselves. And so that they can work well, they also provide you with high-quality testing equipment. There are big differences here. It is worthwhile - both for customers of the testing service provider and as applicants - to ask about the brand of the measuring and testing devices. Whether a testing service provider relies on high-quality work equipment at this important point or prefers to save, says a lot about its philosophy as a service provider and as an employer.

ESG tip: ESG uses test devices from market leader Gossen Metrawatt (Secutest Pro, Profitest MXTRA) as well as the test software MEBEDO ELEKTROmanager for a high-quality e-check according to DGUV regulation 3. Customers and applicants should expect this or a comparable claim from any service provider for electrical testing.

On the road throughout Germany as a test technician according to DGUV regulation 3

A test technician is always on the road a lot and rarely more than a week in an area of ​​work. He is responsible for customers in a wide variety of industries and gets to know many corners of Germany. A company car is available to him for the high travel activity, in which he can easily store his extensive test equipment.

In addition to the suitable work equipment for electrical testing in accordance with DGUV regulation 3, every test technician receives a detailed training period. In this, he familiarizes himself with his work equipment, but also learns the company philosophy. Because in addition to specialist knowledge, responsible electrical testing is also a matter of attitude. People who work in the testing business appreciate the responsibility they bear and work accordingly precisely and with concentration.

Back office colleagues prepare electrical tests according to DGUV regulation 3

In order to do justice to the responsible task of electrical testing, a well-established back office is also necessary. The colleagues in the back office prepare the upcoming test, summarize important information and support the test technician in his field work.

Normally, this creates a healthy relationship between a very independent and self-determined activity and the important exchange with colleagues in the office. Because working independently does not mean working alone. Prospective test technicians should value this support and discuss this during the interview.

The test technician therefore receives all the information he needs for his test day or the entire test week from the back office. This includes customer address, contact person, important conditions on site and the scope and type of electrical test. With his company car and all the testing equipment in his luggage, he makes his way to the customer. As described, this is often not close to home, so that a hotel stay is organized for the technician in the field. He shouldn't have to worry about it himself.

What happens to the customer?

The company is already prepared on site for the inspection technician's visit by the back office. In the best case, he has a permanent contact person with whom he goes through all the points again and can inspect the premises in advance. The test technician for electrical tests according to DGUV regulation 3 does not run anonymously through the building, but is in contact with the customer and the employees of the respective company.

A friendly demeanor is therefore important, as is the necessary self-confidence to make room for the exam. Any locked rooms must be opened and employees must be asked to leave their workplace briefly for the time of the electrical test.

There is then a certain time window for the electrical testing of electrical devices, machines and systems that should be adhered to so that the test technician can manage his quantities. As a rule, in addition to his fixed salary, he also receives a commission per candidate. So he has a high level of self-interest in working quickly.

How does the electrical test according to DGUV regulation 3 work?

The test equipment is designed so that the electrical test can be carried out as quickly and conveniently as possible. It can vary from testing company to testing company. At ESG, the so-called ESG Racer is used for all tests. This is a mobile service trolley with electrical equipment, with which the high-quality test equipment is conveniently transported. An integrated table top at hip height also makes it easier to work while standing. The test technician can use it to efficiently move his equipment from room to room on castors.

After the visual inspection, measurements are made with different test tools, depending on the type of equipment. For example, the Secutest Pro is used for device testing. He uses it to check all monitors, table lamps, printers, kettles, etc.

He uses the Profitest MXTRA for the electrical testing of systems. This is used to test electrical systems such as sub-distributors, sockets or lamps. The Profitest MXTRA is also the right test tool for electrical testing of machines such as printing machines or milling machines.

After the electrical test according to DGUV regulation 3, the labeling and documentation are carried out

After the test, the test technician attaches a corresponding test sticker with an identification number, barcode and the next test date. He takes defective test items out of operation and discusses the next steps with the customer. The complete results are documented in detail immediately after the electrical test. This is done via a connection between the measuring device and the laptop.

Once the electrical test has been completed, the test technician prepares the data obtained for legally compliant test documentation and sends it in encrypted form to his colleagues in the office. Here, too, concentrated and responsible work is important. Because if data is lost, the test was (almost) in vain.

Before the test day is completely over and the end of the working day begins, the test technician also discusses the test job with the office. This means that at the end of the day, the office staff can provide the customer with legally secure test reports online.
