Insulation testers 
At PCE-Group you will find insulation testers for a variety of ranges between 50 mega ohms and 2000 mega ohms. These portable manual insulation testers are used for determining insulation resistance, continuous current, alternating current and testing. With our insulation testers, measurements can be taken for different voltages, beginning with 100V up to 10,000V. Measurements meet the DIN VDE 0413 part 1 standard. Insulation testers come with a test mechanism, clips, batteries and a carrying case. Insulation testers can be equipped for test laboratories if an optional DIN EN ISO is acquired. Measurement of insulation in cables and motor coils is vitally important for the prevention of accidents and damage to installations and is obligatory according to most codes of conduct.  If you don't find the insulation testers you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: +44 ( 0 ) 191 377 3398 and our technical staff will advise you regarding our products.

Information for taking measurements with an insulation tester: When should a measurement be taken?
A measurement should be taken when new work, renovations, repairs, replacements or in cases of damage. Additionally, there are in existence prescriptions for taking regular measurements over specific periods in industrial installations. Such tests should also be made in the private sector as insulation values deteriorate over time, due to humidity, environmental conditions, because of defects or for countless other reasons. Insulation testers are used with and electronic oscillation generator incorporated, which increases the power of the battery across a transformer. The readings are displayed on the insulation either by way of a needle or digitally. In our range of insulation testers you will find a product for any application and for any situation.

How to measure using an insulation tester?

- disconnect power source

- connect the N and PE cables between two points

- disconnect the fuse from the device being measured, then connect the LS and FI cables and then reconnect the power

- connect the measurement cables between to phase conductor and PE and between the phase conductor and N, then connect the insulation tester and take the measurement. It seems sensible to us to take a measurement between the conductor phase to easily detect damage or aging of the lines. The minimum values of resistance of an insulation tester for measurement of voltage should be 250V DC 0.25 MΩ, at 500V DC 0.5 MΩ and at 1000V DC 1 MΩ.

Please take into account that the following points for an insulation tester:

1. Follow the instructions of use exactly as stated.

2. Don't expose insulation testers to extreme temperatures or humidity such as water

3. Avoid extreme moisture.

4. Don't use insulation testers when there is gas, inflammables, vapours or solvents present.

5. Don't use insulation testers near strong strong electrical (motors, transformers, etc.)

6. Before turning on an insulation tester, ensure that operating conditions are stable.

7. Repair and maintenance work on insulation testers, as well as opening them, must be carried out only be specially trained technicians of PCE Group.

8. Special care should be taken when working with voltages in excess of 25V (AC / DC). Contact with high voltages can cause death.

9. Each time the range of measurement is changed, the insulation testers contact should be removed from the object being measured.

10. Before taking a measurement, the user should check the test points of the insulation tester to ensure they are not damaged or broken.

11. Don't touch the points of measurement as this will effect the readings.

12. Voltage between the device and ground cannot go beyond CAT III 1000V.

13. Don't place insulation testers with their control panels face down on a table or work surface, as this may damage the device.

14. Never make changes or modifications to the insulation meter.
