Multirange Motor-cum-Hand Driven Insulation Tester

About.

The CIE/777 HM/MR combines the dual-scale (inner/outer) multirange capability of the CIE/777/MR with the motor-and-hand dual-drive of the CIE/777 HM. All five MR series (MR-A to MR-E) are available in this configuration. The motor-driven mode enables sustained PI and dielectric absorption testing; the hand-crank backup allows operation where mains power is unavailable. Physical specifications (weight, dimensions) vary by series - contact us to confirm for the specific MR/HM variant required.

• Remote field testing with backup hand drive - dual-scale multirange coverage
• Multi-voltage HV commissioning and PI testing
• EPC contractors and utilities needing both motor and hand-drive flexibility
