2 Safety Features and Precautions The SECUTEST®SII test instrument has been manufactured and tested in accordance with the following safety regulations: IEC 61010-1 / DIN EN 61010-1 / VDE 0411-1 and DIN VDE 0404, DIN VDE 0413 Part 2 and 4. When used for its intended purpose, the safety of the user, the test instrument and the device under test (electrical equipment or electrical medical device) is assured.
3 Initial Start-Up 3.1 Connection to the Mains (230 V, 50 Hz) U L – N = 230 V ➭ Connect the mains plug at the test instrument to the mains power outlet. The function selector switch can be set to any position. If a mains outlet (earthing contact outlet) is not available, or if only a 3-phase outlet is available, the adapter socket can be used to connect the phase conductor, the neutral conductor and the protective conductor.
3.2 Automatic Recognition of Mains Connection Errors The device automatically recognizes mains connection errors if the conditions in the following table have been fulfilled. The user is informed of the type of error, and all measuring functions are disabled in the event of danger.
4.3 Adjusting Contrast MENU Set the selector switch to MENU. Select the Setup menu, “back” is highlighted. Activate contrast adjustment. Press and hold the key. Adjust contrast. Return to the menu. Store the contrast setting to permanent memory with the save function in the setup menu. GOSSEN METRAWATT GMBH 4.
5 Classification of Devices Under Test 5.1 Safety Classes Devices assigned to all of the following safety classes are equipped with basic insulation, and provide for protection against electrical shock by means of various additional precautions as well. Safety Class I Devices Exposed, conductive parts are connected to the protective conductor so that they are not charged with voltage if the basic insulation should fail.

Select parameter and acknowledge, change setting and acknowledge. Settings x / – … = function activated / deactivated Limit values ... Illumination Background illumination for the LCD.
9 Individual Measurements MENU 9.1 Measuring Protective Conductor Resistance Resistance is measured: • Between each exposed conductive part of the housing and the earthing contacts at the mains and the device plug (if a removable mains connector cable is used), or the protective conductor terminal for permanently installed devices.
Combined Test – Differential Protective Conductor Resistance Zero balancing is also possible for protective conductor measurement. With zero balancing, all subsequent measurements are adjusted with an offset such that 0 Ω is displayed for a selected reference point which is connected to the protective conductor.
Minimum Allowable Limit Values for Insulation Resistance Sequence ☞ Note All switches at the device under test must be set to the on position during measurement of insulation resistance, including temperature controlled switches and temperature regulators as well. Measurement must be performed in all program stages for devices equipped with program controllers. Test Standard Test Voltage RISO SC I SC II SC III Heat VDE 0701 Part 1:2000 1 MΩ 2 MΩ 0.25 MΩ 0.3 MΩ ∗ VDE 0702: 2004 1 MΩ 2 MΩ 0.
9.3 ! Measuring Leakage Current Attention! During leakage current measurement it is essential to ensure that the DUT is operated at mains voltage. Exposed conductive parts may be subject to hazardous contact voltage during the test and may not be touched under any cricumstances. (A mains shutdown takes place when the leakage current exceeds approx. 10 mA). Select the Ixx measurement and start. 9.3.
9.4 Maximum Allowable Limit Values for Equivalent Leakage Current in mA Equivalent Leakage Current General Measurement of equivalent leakage current is required for: • DIN VDE 0701 and 0702, after passing the insulation L test mA Test Standard IEL VDE 0701-1: 2000 SC I: 3.5 1 mA/kW 1) SC II: 0.5 VDE 0702: 2004 3.5 1 mA/kW 1) SC II 0.
Sequence Current, which would flow during leakage current measurement conducted in accordance with device regulations and with nominal line voltage, is displayed during this type of equivalent leakage current measurement. Leakage current measurement in accordance with the respective device regulations is usually not possible, because the device would have to be set up in an electrically isolated fashion, or connected to an earth isolated power supply to this end. 9.5 Probe Voltage Uprobe – Max.
9.6 Alternating / Direct Voltage UAC/DC – Max. 253 V (feature F01) Direct, alternating and pulsating voltages of up to 253 V can be measured between the N (2) and L (3) connector jacks. 9.8 Measurements with Accessories (feature F01) 9.8.1 Alternating Current IZ with Clip-On Transformer (feature F01) Connection Select the UAC/DC measurement and start. 9.7 Resistance R (feature F01) Resistance of up to 150 kΩ can be measured between the PE (1) and N (2) connector jacks.
9.8.2 Temperature T with Pt100/1000 Sensor (feature F01) Connection Zero Balancing Sensor cable resistance can be compensated with this function: ➭ Short circuit the ends of the sensor leads and determine resistance as shown below. Zero Balancing The determined value can be stored directly ( key) or changed first. The data entry menu is opened with the key.
10 Function Test The device under test can be subjected to a function test with line voltage via the integrated test socket. Function Test In addition to testing with the selector switch in the function test position, or with the Function parameter in the MENU position (feature F01 only), a function test can also be performed immediately after safety testing has been passed in accordance with the selected standard (not possible for safety class III devices).
Short-Circuit Test 1 Test for shorts between conductors N and L. 2 Test to determine whether or not the N or L conductors are shortcircuited to the protective conductor. The test socket can be rendered voltage-free with the key (14), or the function test can be ended with the key (12). ☞ Note A short-circuit at the device under test is recognized automatically by the test instrument. A message appears at the display (9), and the function test is disabled.
11 Measurements – Selector Switch Settings for Standards If measurements need to be performed in accordance with given standards which require specific tests, and if results need to be documented with a test report, an automatic test sequence is advisable instead of individual measurements. ➭ Connect the SECUTEST®SII to mains power. A mains connection test is initialized (see chapter 3.2 on page 10). ➭ Connect the DUT to the test socket at the SECUTEST®SII (see chapter 7 on page 14).
