Description :

The Hioki IR4056-20 insulation tester delivers enhanced comparator (comparative judgment) functionality and notification of judgment results using light and sound, allowing operators to assess results at a glance, yielding significant improvements in work efficiency.

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.
