METRISO TECH

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
