Measuring Instrument for Measurings per EN 62353 and DIN VDE 0701-0702 with american plug & socket    

The SECULIFE SR offers all of the advantages of a universal, computer controllable measuring instrument for the field of medical technology. It’s used for testing the electrical safety of medical devices after repair or modification, and for conducting periodic tests at regular intervals.

Applications
Testing for the Electrical Safety of Electrical Medical Devices in Accordance with the German Medical Product Law (MPG) / MDD
The test instrument is used for quick and safe testing and measurement of repaired or modified electrical medical devices or their components (e.g. patient ports) in accordance with IEC 62353.
Observance of technical safety requirements allows the user of the test instrument to operate electrical medical devices in a hazard-free fashion. The safety of the patient is also assured through the use of tested electrical medical devices.

The device under test can be connected:

• To the test socket with or without adapter for various types of mains connection
• With an adapter for extension cables
• With or without multiple outlet sockets 10 application parts can be connected

Operation:
There are two different operating modes.

• Local: measurements are conducted at the operating panel of the measuring instrument.
• Remote: measurements are controlled via PC. The user has the possibility to integrate all measurements into the individual operator interface at the PC and to define test sequences.

The following are measured:

• Protective earth resistance
• Insulation resistance
• Equipment leakage current
• Touch current
• Patient leakage current (AC/DC portions are measured separately)
• Applied parts leakage current Measuring methods for leakage current measurements:
  • Direct method
  • Differential method
  • Alternative method 

Function Test with Power Analysis (also suitable for high power devices under test up to 16 A) 
The device under test can be subjected to a function test with mains voltage via the integrated test socket.
The following are measured or automatically calculated during the function test:

• Line voltage (RMS)
• Load current / current consumption (RMS)
• Active and apparent power
• Power factor

Further Measuring Functions

Testing for Correct Mains Connection
The measuring instrument’s protective conductor connection is tested each time the start-stop key is pressed. If a voltage of greater than 25 V is detected between the protective conductor and the finger contact, no measurements are possible.

Mains Plug Polarity Reversal
Mains plug polarity need not be reversed manually. It is performed in the form of a mesurement upon request.

Protective Earth Testing (4-pole Measurement)
With at least 200 mA test current

Insulation Test
By means of insulation resistance measurement

Leakage Current Test
by means of equipment leakage current, touch current, leakage current of applied parts with mains on applied parts based on the methods of direct, equivalent leakage current or differential current measurement.
