Test Instrument for Insulation, Low-resistance and Voltage Measurements
The METRISO 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)
– SEV 1000 (Switzerland)
– and regulations specific to other countries as well
Insulation measurement per EN 61557-2 / VDE 0413 part 2
Low-resistance measurement per EN 61557-4 / VDE 0413 part 4
Voltage testing and measurement up to 1000 V
Compact and rugged – for service calls under harsh conditions and laboratory use
- Digital and analogue display, backlit
- Intelligent filter – precise and measurement-dependent activation for the measurement of very high resistances
- – beating, i. e. compensation of 16 2/3 Hz and 50 Hz interference
- – attenuation of capacitive influences from power cables, etc.
- – suppression of electric field influences
- Signalling of dangerous contact voltage by means of LED
- Indication of limit value violations by means of LED
- Overvoltage protection – protects the instrument in the event of inadvertent connection to mains power
- Fuse link for all resistance measuring ranges
- New: Electronic fuse for protection of the low-resistance measurement RLO also protects the fuse link in the low-resistance measuring range in the event of faulty operation
- One measuring point self-test with test resistance of 10 MΩ per EN 50110 / VDE 0105-100
- Guard terminal for compensating surface current
The insulation measuring instruments are suitable for the following tasks:
- Measurement of insulation resistance at voltage-free devices and systems, up to 1000 V
- 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
Practical sets wit remote triggering and ever-ready case
