Million Mega Ohm Meter” is an ideal instrument for measuring high resistance & insulation. Since it applies a high table, IC regulated, H.T. of DC across the across their test , it serves the purpose of a Megger also . Iterasures the insulation resistance of the sample under stress , bysubjecting it to the set voltage . It has a measuring range in six decade ranges & is capable of reading (10 13 ohms) with accuracy . Op - Amp ensure low drift , low input bias current & high stable performance . A separate Rx - NORM - HT switch with amber color lamp indication facilitates to link or de - link HT with terminal . The HT can also check by & set accuracy in HT position by observing FSD & using fine & coarse HT controls.
