1. Introduction I
The MTN/VM220 VibrationMeterisa rechargeable,portableinstrumentdesignedtooperatewitha constantcurrent
typeaccelerometertoprovideaccuratevibrationmeasurements.
ConformingtoISO10816-3/7, MTN/VM220 willdisplayRMS,peak,peak-peak,crest factorandbearingconditiononits
pin-sharpcolourscreen.Upto100time-stampedreadingscanbestoredtonon-volatilememory.
The MTN/VM220 isaninvaluabletrouble-shootingtoolforinstrumentationengineersfamiliarwiththeproblemsof
plant vibrationmonitoring,providinganinstantreadoutoftheconditionofbearingsandrotatingparts.
2. Precautions
