Buying Guide: Key Considerations for DC Hipot Test Equipment
- Test scope: Do you need single-function hipot, or an all-in-one unit that covers IR and GB as well?
- Voltage range and accuracy: Ensure the device supports your required max voltage and measurement precision for safety testing.
- Channels and synchrony: Multi-channel testers are ideal for batch testing or complex assemblies; single-channel units may suffice for smaller workflows.
- Interface and integration: Look for USB/RS-232 compatibility, and consider how easy it is to export test data to your lab information system.
- Build and origin: Whether you prefer a US-made unit for maintenance predictability or a cost-efficient model for budget projects.
- Calibration: Consider options for metrological calibration and whether the vendor provides verification reports or on-site calibration.
- Display and usability: A large color touch display can speed setup and reduce operator errors.
- Safety and compliance: Ensure the product aligns with relevant standards and provides clear safety features during HV testing.
