About This Instrument
The CIE/777/MR is a motorised multi-voltage insulation tester with dual-scale display. Five series (MR-A to MR-E) each cover a different combination of test voltages and insulation scale ranges. MR-A, MR-B, and MR-D feature dual-scale (inner/outer) display; MR-C and MR-E are single-scale. Specify the MR series required when ordering.
