The following functions simplify your measuring tasks:

• Warning in case of dangerous contact voltage
• Quick test with red LED indicator on the instrument
• Measuring voltage: 50 V to 1000 V DC
• Measuring range: 100 to 1 TΩ
• Low-resistance measurement from 0.01 to 10 Ω per DIN VDE 0413 part 4
• DAkkS calibration certificate included
• Overvoltage protection
• Test resistor per VDE 0105-100 (EN 50110)
• METRISO G1000+ only 
  • PI, DAR, DD, Uvar, Uramp 
  • ETC report generating software 
  • - Bidirectional data transmission, 
  • - Creation of data structures
• With the so-called 1 mA test per DIN VDE 0845 / EN 61645, the test instrument also allows for on-site testing of the trigger voltage of overvoltage components (varistors, Zener diodes, etc.) of requirement categories B and C / SPD type 2 and 3 and for subsequent evaluation in conformity with manufacturer's data.

Your Advantages:

• Intelligent filter - precise and measurement-dependent activation for the measurement of very high resistances in the case of:
  • → Beating, i. e. commpensation of 16 2/3 Hz and 50 Hz interference
  • → Attenuation of capacitive influences from power cables, etc.
  • → Suppression of electric field influences
• 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
  • → Electronic fuse for the protection of low resistance and resistance measurement RLOand R

Measurements which are more and more in demand:

Initially, these will include antistatic measurements for floors and walls which serve to protect sensitive electrical components. The so- called polarization index (PI) will become more important as well: This is a long-term insulation measurement, during which measured values obtained after one minute and after ten minutes are compared with each other.

Insulation resistance values acquired over a period of ten minutes may provide information regarding defects, as well as penetration by contamination or moisture. If the insulation is intact, insulation resistance is initially low, and then increases. The curve usually flattens out in the case of contamination or moisture. IEEE standard 43-2000 specifies reference values for measurements at motors and generators.

These measurements can be performed with the new Metriso G1000+ with any measurement voltage. Whereas the polarization index (PI) is used with preference for large objects, the dielectric absorption ratio (DAR) serves as a subset of the polarization index for smaller machines. In this case, insulation resistance measurements after 30 and 60 seconds are compared with each other.

Applications

These instruments fulfills all requirements of applicable European and national EC directives. We confirm this with the CE mark. The relevant declaration of conformity can be obtained from GMC-I Messtechnik GmbH.

METRISO G500/G1000 insulation and resistance measuring instruments allow for quick and efficient testing of protective measures in accordance with DIN VDE 0100, ÖVE-EN 1 (Austria), NIV/NIN SEV 1000 (Switzerland), and regulations specific to additional countries. 

The test instrument is especially well suited for:

• Systems set-up
• Initial start-up
• Periodic testing
• Troubleshooting in electrical systems

The following measurements and tests can be performed with the insulation measuring instruments:

• Insulation resistance
• Low-resistance 
• Voltage

The following can also be tested by using a shielded measurement cable:

• Floor covering electrostatic discharge capability
