In electrical safety evaluation, particularly for mains-connected equipment and medical devices, leakage current measurement is a critical parameter. Small currents, imperceptible under normal conditions, can pose a significant risk in sensitive applications such as those involving direct contact with the user or patient. This instrument has been certified to perform these tests by several international bodies.
The LT-601 Digital Leakage Current Tester is an instrument designed to make these measurements in accordance with international standards, allowing safety conditions in electrical and electronic equipment to be verified under different test scenarios.
Leakage current measurement in different configurations
The instrument evaluates different types of leakage current, covering the most relevant configurations in safety testing:
-
Measurement through the equipment’s ground conductor
-
Leakage current from surface or patient to ground
-
Current between contact points (patient to patient)
These configurations simulate real conditions of use and detect potential electrical hazards in the equipment under test.
Compliance with international standards
The LT-601 is designed to meet widely recognized electrical safety standards, including:
-
UL
-
CSA
-
CE
-
EN
-
IEC
-
MIL
In particular, it is compatible with the requirements of IEC 60601, the key standard for medical equipment, which sets strict limits for leakage currents under normal and fault conditions.
For example:
-
DC leakage currents typically limited to very low values (on the order of microamperes)
-
Different limits for normal condition and single fault condition
-
Specific restrictions depending on the operating frequency
Meeting these criteria is essential to ensure the safety of the user or patient.
Simulated impedance networks
The instrument incorporates impedance networks that reproduce the electrical behavior of the human body in accordance with standards such as:
-
IEC 60601
-
EN 60601
-
CSA 601
-
UL 2601
This ensures that measurements reflect realistic conditions, so results are representative of the actual use of the equipment being evaluated.
Accuracy and measurement capability
The LT-601 offers measurement ranges suited to detecting leakage currents at very low levels, with high resolution and accuracy:
-
200 µA range with 1 µA resolution
-
2000 µA range with 10 µA resolution
-
Accuracy of ±1% of full scale
These characteristics identify small deviations that could go unnoticed with less sensitive instruments.
