standards and regulations: Standard DIN EN 61557-1:1998-05 DIN EN 61557-2:1998-05 VDE regulation VDE 0413 Part 1:1998-05 VDE 0413 Part 2:1998-05 “Equipment for testing, measuring or monitoring protective measures in systems with line voltages of up to 1000 V AC and 1500 V DC, part 2, insulation resistance measuring instruments”. The instrument is suitable for the measurement of insulation resis- tance at voltage-free devices and equipment with nominal voltages of up to 1000 V. It is also suitable for the measurement of insulation resistance with values of up to 1 TΩ, and open-circuit voltages of up to 5000 V. The instrument is also equipped with a 1000 V measuring range for direct and alternating voltages. This provides users with the advantage of checking devices under test for the absence of voltage, and dis- charging capacitive devices under test. All of the values required for approval reports can be measured with this instrument. 6 DranISO 5000D User’s Guide 2 Safety Features and Precautions The DranISO®5000D test instrument has been manufactured and • Measurement may only be performed on voltage-free equipment tested in accordance with the following safety regulations: and devices. • Measurements may not be performed under moist ambient condi- Standard DIN EN 61557-1:1998-05 tions, where condensation has occurred, or in explosive atmo- DIN EN 61557-2:1998-05 spheres.
