Gossen Metrawatt METRISO BASE Test Instrument
The METRISO BASE insulation and resistance measuring instruments allow for quick and effective testing of protective measures in accordance with:
- Digital and analogue display, backlit
- 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 by means of LED
- Indication of limit value violations by means of LED
- 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
- Guard terminal for compensating surface current
