Gossen Metrawatt METRISO G1000 (M550B) Features:

  • 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
  • Backlit dot matrix display for measured and limit values
  • Timer function 1 s ... 100 min
  • 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
  • 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.
