To ensure the safe use of electrical products, electrical safety tests such as insulation resistance, withstand voltage, ground resistance, and leakage current must always be conducted. Hioki Leakage Current Testers comply with laws and standards regarding medical electrical equipment as well as non-medical electrical equipment, and can be used to measure leakage current in all types of electrical products from computers to medical equipment.

The ST5541 provides support for standard-compliant networks (excluding medical-use electrical devices).

 

Key Features

• LEAK CURRENT HiTESTER ST5541: A low-cost solution that complies with standards governing general-use electrical devices
• Uninterrupted polarity switching function dramatically reduces cycle time
• Support for rated currents up to 20 A gives the instrument more than adequate capability for testing products designed to comply with new standards
• Touch panel features simple, interactive operation
• Communications functionality and external I/O support allow automatic testing on production lines

 

Leak Current Measurement - Essential to Electrical Safety

Compliance with IEC 60601-1:2005 (3rd Edition) is now mandatory.

The ST5540 series features an improved measuring method and dramatically faster cycle times thanks to its uninterrupted polarity switching capability. The new devices support rated currents of up to 20A, making it more than ideal for use with products built to new standards.

 

 

For Standard- and Regulation-compliance Measurement of General-use Electrical Devices

There are various standards in place concerning networks (body simulated resistance), and a standard-compliant network is required in order to make measurements.
ST5541 provides standard support for standard-compliant networks (excluding medical-use electrical devices).

 

 

3157 Safety Standard for Hospital Electrical Equipment JIS T 1022:2006 Measurement

Combination of Instruments for Leak Current Testing and Safety Conductor Testing

The following are key parts of any safety inspection of electrical equipment:
•Leak current test: Measure with the ST5540 and ST5541.
•Safety conductor test (also known as a ground line resistance test or ground conductor test): Measure with the 3157.
The 3157 can also be used for conducting measurements under the JIS T 1022:2006 safety standard for hospital electrical equipment.
