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.
The insulation measuring instruments are suitable for the following tasks:
- Measurement of insulation resistance at voltage-free devices and systems, up to 1000 V
- Checking of test objects for absence of voltage in systems with up to 1 kV
- Testing of the resistance of earthing conductors, protective conductors and equipotential bonding
- Testing of electrostatic discharge capacity at floor coverings (using shielded measurement cables) - EN 1081
- With the help of the so-called 1 mA test per DIN VDE 0845/ EN 61645, testing for the triggering of performance category B and C / SPD type 2 and 3 surge protection devices (varistors, reference diodes etc.) can be executed with this measuring instrument, on-site as well, and evaluated in accordance with the manufacturer’s data.
Discharging Capacitive Devices Under Test
Capacitive devices under test such as cables and coils, which may be charged with test voltage, are discharged by the measuring instrument. The falling voltage value can be observed at the display.

Your Advantages:
- Intelligent filter - precise and measurement-dependent activation for the measurement of very high resistances in the case of:
- → 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
- 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 RLO and R
Measurements which are more and more in demand:
Initially, these will include anti static 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.
