UT505B
True RMS-isolationsmodstandstesteren kombinerer funktionerne fra et digitalt multimeter og en isolationsmodstandstester. Udover de typiske multimeterfunktioner kan disse målere også måle isolationsmodstand, PI og DAR for at bestemme isolationsstatus. UT505 kan bruges til isolationsmodstandstestning af præcisionsværktøj, motorer, kabler, transformere, afbrydere, elektriske apparater og isolerede materialer.
