Detailed Product Overview
In installation and maintenance work, insulation resistance testing is commonly required when checking wiring, distribution boards, motors, or electrical equipment after repairs. In many cases, a dedicated insulation tester is the practical choice, without the need for a full PAT tester or multifunction installation tester.Practical PASS/FAIL Indication
The integrated comparator evaluates the insulation measurement in approximately 0.8 seconds and indicates PASS or FAIL. This is particularly helpful when working in confined spaces or overhead installations. PASS and FAIL are signaled acoustically, and in the event of a FAIL result, the display backlight turns red.Protective Conductor (PE) and Voltage Check
Protective conductor (PE) testing is performed with a 200 mA test current in accordance with EN 61557-4. The higher test current helps detect poor connections, oxidized contacts, and increased resistance at terminals – unlike the low-current continuity function of a typical DMM.Designed for Everyday
Use The IR4056 complies with CAT III 600 V and has been drop tested to 1 m. The solid hard case forms a single unit with the instrument and provides space for test leads and accessories. The test leads remain connected to the instrument – even during transport. The high-contrast display remains clearly readable even under difficult lighting conditions, and a bright backlight supports work in dark distribution boards.- IR4056-20
