Service is a matter of course for us. Therefore, we do not offer service contracts that are subject to fees. Whenever you have a technical question or problem, just contact us. It is irrelevant whether your device has been acquired recently or is already 15 years old. We will help you in any case.
We grant a guarantee of 48 months from the date of purchase for all devices if they were purchased within the EU. For devices purchased outside the EU, we grant a guarantee of 24 months from the date of purchase.
Of course you can send your Power Choke Tester to us for recalibration. We will perform the manufacture calibration in-house within one to two working days. The calibration is based on international standards and includes a calibration certificate.
Further information of calibration process
At each calibration we open the devices and subject them to a thorough visual inspection. We also check the function of internal safety devices and circuits. For the factory calibration, we use specially developed, self-made inductance standards, which meet the special requirements through the pulse measurement procedure of our devices. Other inductance standards commonly used in calibration laboratories are usually unsuitable because they are neither designed for high pulse currents nor have sufficient frequency response. Since our devices can also operate with very short pulse times of <3 μs, the frequency response of the ohmic resistance is also important for the precision of the inductance measurement. For customers from overseas, we offer a calibration kit including calibration instructions, which can be used to perform the calibration either by itself or by a local calibration laboratory. It contains three long-term stable, very accurate inductance standards (100 μH, 1 mH, 10 mH) in the ABS / PA rack, a low impedance switchable resistor array (6 values from 10 mΩ to 10 Ω, < 0,08%, TK < 20ppm) and a test lead set. For the model DPG10-100B, DPG10-3000B and DPG10-4000A additional inductance standards are necessary, which can be supplied separately.
For our customers in Europe, the calibration in our house is, however, more economical and meaningful, since a necessary adjustment can only be done by us.
We perform repairs or recalibrations quickly and at fair conditions (usually within one or two working days).
Here you can download datasheets of DPG – series devices and further informations as pdf-documents.
We are continuously developing our software. Software updates are always free. The software package includes the DPG10 software, the actual version of the instruction manual and the demo application of LabVIEW VIs for integration in automated testing environments.
