HIOKI IR4056-20 Digital Insulation Resistance Tester 5-Range 50 to 1000V Periodic Inspection

HIOKI IR4056-20 Digital Insulation Resistance Tester 5-Range 50 to 1000V Periodic Inspection

Product Description:
- Hioki IR4056-20 Insulation Tester
- 5-range testing voltage 50 V/100 MΩ to 1000 V/4000 MΩ
- Stable & medium-speed digital readings, response time at PASS/ FAIL decision 0.8 second
- Drop proof onto concrete from 1m (3.28 feet)
- Bright LED luminous LCD, Test lead with bright LED lamp to illuminate near hand (Optional)
- Continuity check via 200 mA testing
- Built in AC/DC voltage meter, useful for testing solar power generation systems and electric vehicles
- The comparator compares measured values to pre-set reference values to make pass/fail decisions. Thanks to improved response performance, the Hioki IR4056-20 Insulation Tester provides an instantaneous pass/fail decision when the test lead is placed in contact with a target.
- Furthermore, the comparator function allows operators to assess pass/fail decisions based on light and sound cues. “Pass” conditions are signaled by a short beeping sound and a green LED, while “fail” conditions are signaled by a longer, continuous tone and a red-backlit measurement screen. When used with the optional Test Lead with Remote Control Switch L9788-11, the “fail” condition can also be easily identified by the lead’s red LED.
- It is not unusual for technicians to need to measure more than 100 locations in a single building, so the instruments’ ability to generate a continuous series of pass/fail decisions will yield significant improvements in work efficiency.
- Most measurement targets consist of long cables that have already been laid in a facility. Consequently, insulation resistance readings are often unstable due to the effects of noise emitted by nearby electrical wiring and other sources of interference. The Hioki IR405620 Insulation Tester employes a variety of measures to stabilize the display of readings so that it is easy to read measured values, even in challenging environments.
- The Hioki IR4056-20 Insulation Tester provides functionality for generating high-voltage 500V and 1,000V output when testing high-voltage equipment. Normally, inadvertent application of a high voltage to a low-voltage device can damage the device. To protect against this risk, the new instruments provide functionality for preventing the application of unintentional high-voltage output
- Outputting 500V or 1,000V requires two steps: placing the function key in a certain position and then pressing a flashing key to cancel the high-voltage output lock feature. In this way, the instruments are designed to prevent inadvertent output due to mistaken function key operation.
- There is growing need for instruments capable of DC voltage measurement due to increasingly widespread use of solar power and electric vehicles. As a result, HIOKI designed the Hioki IR4056-20 Insulation Tester with both AC and DC voltage measurement functionality.
- In addition to low-resistance measurement at 200 mA DC, the Hioki IR405620 Insulation Tester support JIS C 60364-compliant insulation measurement of safety conductors in building electrical equipment and indirect safety contact testing in electric and hybrid vehicles
