Test Instrument for Insulation, Low-resistance and Voltage Measurements

Compact and rugged - for service calls under harsh conditions and laboratory use

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

Applications

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

Technical characteristics

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
