Detailed Product Overview
In installation and maintenance work, insulation resistance measurements are routinely carried out when checking wiring, distribution boards, motors and electrical equipment after repairs or during periodic inspections. For these tasks, a dedicated insulation tester is often the appropriate choice instead of a multifunction installation tester or combined test instrument.Digital Bar Graph and Fast PASS/FAIL Evaluation
Alongside the numeric measurement display, the IR4057-90 includes a digital bar graph for continuous visual indication of insulation resistance during testing. Resistance changes can be observed directly on the scale. The comparator function evaluates insulation measurements within approximately 0.3 seconds and indicates PASS or FAIL acoustically and visually. In the event of a FAIL result, the display backlight turns red.Protective Conductor Testing and Voltage Measurement
Protective conductor testing is performed with a 200 mA test current in accordance with EN 61557-4. The defined test current applies sufficient load to the protective conductor connection to identify increased contact resistance, loose terminals and oxidized connections. This provides a more reliable assessment than a low-current continuity check performed with a standard digital multimeter.For Daily Field Work
The IR4057-90 complies with CAT III 600 V and has been tested for a 1 m drop onto concrete. It is specified for operation in ambient temperatures from -25 °C to 65 °C. The instrument is integrated into a protective hard case that forms a single unit and provides storage space for test leads and accessories. Test leads remain connected during transport.- IR4057-50 Digital Insulation Tester
