This guide provides a quick overview of standards and types of test equipment.
Where Is Test Equipment Used?
The field of measurement and test equipment is broad. From endoscopes to voltage testers to oscilloscopes, the range of solutions supports a wide variety of use cases.
Test equipment is generally used to verify the functionality of electronic devices, machines, components, processes, and systems. These tests are critical, as undetected faults in electrical systems can be costly—or even life-threatening.
Depending on what you're testing, different equipment may be needed. From basic multimeters to high-end systems, for industrial or personal use, the sheer number of test instruments can be overwhelming.
What Types of Test Equipment Exist?
Accurate and reliable measurements require dependable test equipment. Common instruments include:
- Ground Resistance Testers: Measure grounding resistance using current and voltage comparisons.
- VDE Testers: Verify compliance with VDE safety standards for electrical installations. Different models offer varying functionalities based on testing requirements.
- Network Analyzers: Used in electronics to analyze complex systems. Available as both handheld and bench-top models.
- Light Measurement Devices: Tools like lux meters and spectrometers measure light performance—crucial in industrial lighting verification.
At dataTec, you’ll also find specialized test equipment for rotary field and motor direction, vibration, field strength, material hardness, humidity, and photovoltaic systems.
What Is the Purpose of VDE Standards?
VDE standards provide legal and technical frameworks for safety in electrical systems. These regulations help prevent accidents and damage. They define operation and safety procedures, including necessary tests and documentation.
What VDE Standards Apply to Test Devices?
- DIN VDE 0100 – Testing of fixed electrical installations
- DIN EN 50678 (VDE 0701) – Post-repair testing
- DIN EN 50699 (VDE 0702) – Periodic re-testing
- DIN EN 60204-1 (VDE 0113-1) – Testing of control panels
These standards define mandatory testing and the qualifications required to perform such tests.
Many of these standards are interlinked, forming a complex hierarchy that can be difficult to navigate without expert knowledge.
They often include detailed instructions such as:
- Scope of application
- Order and procedure of tests
- Visual inspections
- Measurements such as:
- Protective conductor resistance
- Insulation resistance
- Protective conductor current
- Touch current
- Substitute leakage current
- Testing intervals (reference values)
They may also specify how emergency stops and system restarts should be handled, EMC requirements (IEC 61000-6-1/-2/-3/-4), and cable installation guidelines.
Where Can I Learn More About VDE Testers and Standards?
dataTec offers professional training on VDE and EN standards through the dataTec Academy in cooperation with TÜV Süd, etz Stuttgart, and BZE Hamburg.

Additional Information About Test Equipment
- VDE test instruments feature digital displays—analog meters are not precise enough.
- The term "test equipment" covers a wide range of tools used to evaluate various measurements.
- VDE standards regulate not only testing procedures but also documentation and reporting.
- Proper training on VDE and DIN norms is essential for any metrology professional.
How Often Should VDE Test Equipment Be Calibrated?
Calibration depends on usage and environmental factors. Field use may lead to damage. Standards usually don’t specify intervals, but manufacturers typically provide recommendations upon purchase.
Which Companies Manufacture Test Equipment?
The market includes many well-known brands like Benning, FLIR, BEHA-Amprobe, Fluke, and Chauvin Arnoux. dataTec offers over 20 brands in its portfolio.
