HIOKI ST5541 Leak Current HiTester

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).

Leak Current HiTester, For electrical devices

Note: For applications involving leak current measurement of medical-use electrical devices, use the ST5540.

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.
