Page 6: Safety Features And Precautions
Safety Features and Precautions The tester is manufactured and tested in accordance with the following standards: IEC/EN 61010-1/ VDE 0411-1 Safety regulations for electrical measuring, control, regulating and laboratory devices – general requirements and DIN VDE 0404 Devices for the technical safety inspection of electrical equipment; Part 1: general requirements, and Part 2: periodic device testing When used for its intended purpose, the safety of the user, the test instrument and the device... -
Page 7: Applications
Applications The tester is intended for the testing and measurement of repaired or modified electrical devices in accordance with DIN VDE 0701 or DIN VDE 702. These regulations require the measurement of protective conductor resistance, insulation resistance and equivalent leak- age current for repaired or modified electrical devices, as well as testing for the absence of voltage at exposed, conductive parts for data processing systems and office machines. -
Page 8: Error And Limit Value Messages
Test Socket The DUT is connected to the test socket for the measurement of protective conductor resis- tance, insulation resistance and equivalent leakage current in accordance with DIN VDE 0701 and DIN VDE 0702, if the DUT is equipped with a mains plug. Connector Jack/Terminal for DUT Phase Conductors This terminal is wired in parallel to the two short-circuited phase conductor terminals at the test socket (8). -
Page 9: Mains Connection
Residual Current Limit Value Violations â The METRATESTER 5/5-F is equipped with a selector switch independent, residual current mon- itoring function. If the red error lamp lights up and no message regarding a limit value violation appears at the display, residual current at the mains outlet is dangerously high – regardless of the selector switch setting. -
Page 10: Testing Protective Conductor Potential
Testing Protective Conductor Potential Bring the contact finger into contact with the contacting surface (4) and, at the same time, with a grounded object (e.g. a water pipe). The PE signal lamp (3) must not light up! Potential between the mains plug protective conductor (1) and the contacting surface (4) is then £... -
Page 11: Connecting The Device Under Test To The Test Instrument
Connecting the Device Under Test to the Test Instrument The DUT must be connected to the test socket (8), or to the jacks or terminals (9 and 10) which are connected in parallel to the test socket for the measurement of protective conduc- tor resistance, insulation resistance and equivalent leakage current. -
Page 12: General Measuring Procedures
General Measuring Procedures Line voltage must lie within the allowable range of 207 to 253 V for all of the following mea- surements. This assures that the accuracy of displayed measured values corresponds with the values specified under “Technical Data” (chapter 11, page 28). Line voltage can be measured by setting the measuring range selector switch to the “250 V”... -
Page 13: Testing Devices Per Din Vde 0701, Part 1: 2000
Testing Devices per DIN VDE 0701, Part 1: 2000 The limit values specified in the following chapters correspond to current revision levels of official standards at the time of going to print. Please note that normative legislation is contin- uously updated to meet the safety requirements necessitated by changing market situations, and that the listed limit values are thus subject to change. - Page 14 Insulation resistance for safety class I has been redefined to 1 M W , and to 0.3 M W for • devices with heating elements. This test is required for all devices for which all charged insulation is monitored during testing (practically all devices without electrically actuated, all-pole relays).

Page 15: Visual Inspection
Visual Inspection Visual inspection is performed prior to measurements with the test instrument. Visual inspection includes: • Housing and protective covers • Connections and external cables including fasteners and plugs • Visible condition of insulation material • Strain reliefs for cables, anti-kink devices and cable routing •... -
Page 16: Measuring Insulation Resistance
Measuring Insulation Resistance This measurement may only be performed if the device under test has successfully completed protective conduc- tor resistance testing. This measurement may not be performed if all-pole electrically actuated switches are included in the device under test. Connect the device under test as described in chapter 4.4, page 11. -
Page 17: Measuring Contact Current
Measuring Contact Current Contact current measurement can be performed instead of insulation resistance measure- ment for class II devices, or for class I devices with exposed conductive parts which are not connected to the protective conductor. Connect the device under test to the mains outlet. Attention! The protective conductor test must first be performed and passed. -

Measuring Insulation Resistance This measurement may only be performed if the device under test has successfully completed protec- tive conductor resistance testing. This measurement may not be performed if all-pole electrically actuated switches are included in the device under test. Connect the device under test as described in chapter 4.4, page 11. -
Page 20: Measuring Equivalent Leakage Current
Measuring Equivalent Leakage Current According to DIN VDE 0702:1995, equivalent leakage current must be measured for safety class I devices: – for which interference suppression capacitors have been installed or replaced during the coarse of repair or modification. – which are equipped with heating elements and for which an insulation resistance of less than 0.5 M W has been measured (chapter 6.3, page 19). -
Page 21: Testing Data Processing Systems And Office Machines Per Din Vde 0701, Part 240
Testing Data Processing Systems and Office Machines per DIN VDE 0701, Part 240 General The following safety relevant tests are required for data processing systems by this regulation: • Visual inspection • Protective conductor test • Testing for the absence of voltage at user accessible, exposed conductive parts Visual Inspection Visual inspection is performed as described in chapter 5.2, page 15. - Page 22 A resistance value of up to 1 W measured between a suitable earthing contact and all exposed conductive parts which might become charged with voltage in the event of an error is allowable for permanently installed devices. To housing for measurement of protective conductor resistance In the case of data processing systems or combinations of permanently installed individual devices, the network should be decoupled and individual measurements should be per- formed.
