Applications
METRISO INTRO/BASE/TECH insulation and resistance measuring instruments allow for quick and effective testing of protective
measures in accordance with DIN VDE 0100, ÖVE-EN 1 (Austria),
NIV/NIN SEV 1000
countries as well. The instruments are equipped with a microprocessor and comply with IEC/EN 61557 / VDE 0413 regulations:
Part 1: General requirements
Part 2: Insulation resistance measuring instruments
Part 4: Instruments for measuring resistance at earthing conduc-
tors, protective conductors and equipotential bonding
Part 10: Combined measuring equipment for testing, measuring
or monitoring protective measures
As well as requirements per VDE 0701-0702:
Repair, modification and testing of electrical devices
The insulation measuring instruments are suitable for the following
tasks:
• Measurement of insulation resistance at voltage-free
devices and systems, up to 1000 V depending upon variant
• Testing of the resistance of earthing conductors, protective
conductors and equipotential bonding
• Checking of test objects for absence of voltage
• Testing of electrostatic discharge capacity at floor coverings
(using shielded measurement cables) – EN 1081
(Switzerland), and regulations specific to other
