VDE- inspection meter Secutest S2N+
Measuring device according to VDE standards 0701/702 and VDE standard 0751 for electro-medical devices

The secutest S2N+ is a universal measuring device to check electronic security for portable electronic equipment in the industrial area. Thus this measuring device is customized to check safety of portable electronic operation devices after maintenance or modification according to DIN VDE 0701 or after regular time intervals (repeating tests) according to DIN VDE 0702. The meter recognizes automatically the safety class of the test object and performs the complex measuring mostly automatically. The in practice most approved DIN VDE 0701/0702 allows in order to evaluate state of isolation besides measuring the isolation resistance additionally the measurement of the leakage current through measuring the differential current that is performed in case of the vde meter S2N+ within a complete performance analysis or performed as an individual examination. Texts about operator guidance, parameterization, measuring and inspection results, connection switch, help text and fault reporting are shown in clear text on a large dot matrix LCD directly at the meter. The application areas include craft, office, industry, nursing- and retirement homes, and hospitals. Via the standard RS232 interface a data transfer from the vde meter to an SI module (data storage), a PSI module (printer with storage) or laptop or computer can be performed. For the computer there is software facilitated that allows creating inspection protocols and including the measuring and inspection results into the operation device management or into the whole administration of the electronic craft. By means of a barcode printer and reader large stocks of operation devices can be administrated time- and money saving and be captured for repeating tests.

Application/ Measuring method

Application/ Measuring method

To check electric safety of electronic operation devices according to BGV A2. The measuring device is meant for quick and secure inspection and measurement of repaired or modified electric devices according to DIN VDE 0701 and for repeating inspection according to DIN VDE 0702. According to these regulations is measured:
- Protective conductor resistance
- Isolation resistance
- Protective conductor current for SK1 devices
- Touch-current (for SK2 devices)
- Zero-potential of touchable conducting parts (= touch-current)
- Patient leakage current (AC/DC- fractions are measured separately)

Measuring methods:
- Direct measurement
- Alternative leakage current
- Differential current

The meter Secutest S2N+ is meant to check and measure repaired or modified electro-medical devices according to DIN VDE 0751 quickly and reliably. The compliance with safety- related regulations allows the user of the inspection meter a safe handling of the electro-medical device. Another point is the safety for patients while using a checked electro-medical devices.

Function/ Functionality

The measuring device recognizes the safety class of the test object and performs a complex measurement fully automatic. The measurement of differential current complies with regulation for repeating test DIN VDE 0702.

Recording functions
All data required for an acceptance protocol or maintenance book (e.g. of ZVEH) for electric production equipment can be measured via this measuring device. The module SECUTEST PSI, a printer with data storage, integrated interface and keyboard is adaptable to the cover and widens the application range of the inspection device. With the measuring and inspection protocol, that can be printed directly via the module SECUTEST PSI or a computer or can be stored on a computer, all measured data can be documented and archived. The same function, but without a printer, is provided by the lower priced storage module SI.

Performance check with analysis (even for high-performance test objects applicable (16 A))
Via the integrated inspection socket a performance check with adapter voltage can be performed on the test object. The performance check can be started immediately after a passed test. Thereby are measured or automatically calculated:
- Adapter voltage, differential current, current draw, effective and apparent power, performance factor, electric energy, start-up time.

Multimeter function
Extensive multimeter function including temperature measurement complements reasonably the measuring potential for the operator. The following single measurements can be performed:
Alternating and direct current, resistance, search phases, current via clamps (equipment), temperature via Pt100 (equipment).

RS-232-interface
Through this connection the data transfer and current supply of the (P)SI- module is purchasable as an equipment. Via an interface cable also other devices, e.g. a computer or printer, can be connected to the interface.

Help-button
With that key information and connection, pictures for current display can be ordered. The information will be displayed in a LCD display-panel.

Function switch
Via the function switch inspection procedures or measuring functions can be picked. A direct assignment of switch setting to inspection regulation facilitates the operation.

Pole change of adapter
A manual pole change of the adapter is not necessary. It is performed during the inspection procedure internally on demand. 

Safety installations
The device monitors the adapter connection. It signals defective or dangerous connections and closes in case of endangerment. 

Display
The LCD display is made of a dot matrix which displays the menu as well as possible settings, measuring values, notes and error indication or even connection circuits.
