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.<\/p>\n

Key Features<\/strong><\/h3>\n

\u2022 5-range testing voltage of 50 V\/100 M\u03a9 to 1000 V\/4000 M\u03a9
\n\u2022 Stable & medium-speed digital readings, 0.8 second response time of PASS\/ FAIL decisions
\n\u2022 Drop proof onto concrete from 1m (3.28 feet)
\n\u2022 Bright LED, luminous LCD, test lead with bright LED lamp to illuminate near hand (Also available in the IR4056-21)
\n\u2022 Continuity check via 200 mA testing
\n\u2022 Built in AC\/DC voltage meter, useful for testing solar power generation systems and electric vehicles<\/p>\n

How to Use Digital Insulation Resistance Meters – Basic Course<\/strong><\/h3>\n

This video explains how to use a digital insulation resistance tester to measure a distribution panel. \u203b Shooting was done with Japanese model IR 4052. The global model name is IR 4057.<\/p>\n

Comparator function provides PASS\/ FAIL decisions at a glance<\/strong><\/h3>\n

Compare measured values to pre-set reference values to generate a pass or fail judgment with the Comparator function. (also pair with insulation resistance measurement and low-resistance measurement) The insulation testers give you pass\/ fail results using a beeping sound, LCD light, and indication right on the test lead with remote control switch*, letting you check for insulation integrity without needing to look at the instrument. (*Standard with the IR4056-21)<\/p>\n

Robust, damage-resistant design<\/strong><\/h3>\n

These instruments feature a robust design that can withstand being dropped onto concrete from a height of 1 m. Difficult to damage, this insulation tester is ideal for use in the field.<\/p>\n

White LED lighting that\u2019s easy to read in dim locations in the field<\/strong><\/h3>\n

The scale is lit by a white LED, ensuring that insulation resistance values are easy to read, even when using the instrument in a dim location.<\/p>\n

Measurement switch designed for outstanding ease of use<\/strong><\/h3>\n

The instrument\u2019s measurement switch can be operated with just the thumb. Press for a single measurement or lift up for continuous measurement of insulation resistance.<\/p>\n

200 mA grounding line continuity check function<\/strong><\/h3>\n

The Insulation testers can perform EV and HEV continuity checks as well as resistance measurement of safety conductors in building electrical equipment as defined by IEC 60364.<\/p>\n
