INSULATION TESTER IR4056-20, IR4057-20 Field Measuring Instruments 5-range INSULATION & CONTINUITY CAT III Ⅲ 600V 600V IEC/EN 61557 AC/DC automatic detection range Model IR4056-20 with Bar Graph QUICK & EASY Comparator Function Improves Work Efficiency • Identify the Insulation and Low Resistance Conditions with the PASS/FAIL Icon • FAIL Alert with Red LCD and Audio Buzzer Stable Digital Readings are Easy to Read Model IR4057-20 2 Efficient, Safe Measurement with Digital Insulation Resistance Testers Solar Power Hybrid Electric Vehicles Periodic Inspection Electric Vehicles Comparator function provides PASS/FAIL decisions at a glance The comparator function compares measured values to pre-set reference values to generate a pass or fail judgment. (Can be used with insulation resistance measurement and low-resistance measurement.) The stable display is easy to read, increasing work efficiency. Instant judgment Identify PASS/FAIL using light and sound Since the IR4056-20 and IR4057-20 generate judgments as soon as the test lead makes contact, it is possible to make a rapid series of measurements in the manner of a continuity check. The IR4056- 20 and IR4057- 20 notify the operator of pass and fail judgments using a beeping sound, LCD light, and comparator indicator on the test lead with remote control switch (optional accessory), allowing determinations of compliance to be made without looking at the instrument. PASS Option When the measured value is greater than or equal to the reference value* Short beep No change Useful when there are numerous measurement locations *In some cases, the capacitance component may prevent a judgment from being made until charging completes. FAIL Green Option When the measured value is less than the reference value* Continuous tone *Insulation resistance measurement Red Red 3 Designed for safety and peace of mind Featuring improved convenience and ease of use Integrated hard case with sliding cover DROP PROOF Testers are built tough to withstand a 1-meter drop onto a concrete floor With cover closed AC/DC voltage measurement (With AC/DC automatic detection function) Test Lead L9787 Use as a tester replacement thanks to DC voltage measurement functionality, which is useful in applications involving solar power and electric vehicles (EVs). Connect either the test probe or alligator clip for the earth side Easy-to-see LCD An FSTN LCD ensures the instrument’s display is easy to read from any angle. Effective maximum display value A “>” mark is displayed when the measured value is greater than the effective maximum display value for the function in use. IR4056-20 200 mA grounding line continuity check function The IR4056-20 and IR4057-20 can perform EV and HEV continuity checks as well as resistance measurement of safety conductors in building electrical equipment as defined by IEC 60364. IR4056-20 Safety-oriented double-action Backlight (White LED) A backlight makes it possible to work in dark or poorly lit locations. 500 V/1000 V range only 1 Set the function key to either 500 V or 1000 2 Press the flashing “RELEASE” key.
