Gossen Metrawatt METRISO XTRA Test Instrument
The METRISO XTRA insulation and resistance measuring instruments allow for quick and effective testing of protective measures in accordance with:
- DIN VDE 0100
- VE-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
- 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 50Hz 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 Mper 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
