Hioki insulation testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The IR4056 is a 5-range, 50V to 1000V digital insulation resistance tester with efficient functions and features to help shorten work time associated with field insulation testing.
5-range testing voltage of 50 V/100 MΩ to 1000 V/4000 MΩ Stable & medium-speed digital readings, 0.8 second response time of PASS/ FAIL decisions Drop proof onto concrete from 1m (3.28 feet) Bright LED, luminous LCD, test lead with bright LED lamp to illuminate near hand (Also available in the IR4056-21) Continuity check via 200 mA testing Built in AC/DC voltage meter, useful for testing solar power generation systems and electric vehicles
The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.
