Metriso Xtra 1000V Insulation Tester

Test Instrument for Insulation, Low-resistance and Voltage Measurements - with Memory

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

The METRISO XTRA 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
• With the so-called 1 mA test per DIN VDE 0845/EN 61645, the instrument also allows to perform on-site tests of the response voltage of overvoltage components (varistors, Zener diodes, etc.) of requirement categories B and C / SPD Type 2 and 3) and to evaluate the test results in accordance with manufacturer‘s data.

Technical characteristics

• Test voltages in fixed increments, variable or as a ramp 50, 100, 250, 500, 1000 V
• Polarization index and absorption ratio
• 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
• Acoustic signalling when limit value is exceeded
• Detection of interference voltage in switch position OFF
• 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
