FEATURES

Accurate, easy-to-use insulation resistance meter
Advanced diagnostics and calculations in insulation testing

Tailored measurement methods with advanced insulation diagnostic functions
When a high test voltage is continuously applied to the circuit under test, the insulation may break down. Failures caused by the application of a high voltage can be prevented by keeping the applied voltage as low as possible while testing the insulation.

The IR5050 is equipped with various insulation diagnostic functions, allowing you to choose the optimal measurement method according to the testing application.


Automatically calculated and displayed insulation diagnostics
After measurement completes, the instrument can display more than just the insulation resistance and leakage current, but also judgement index values of PI, DD, and DAR. It calculates these indexes based on the measured values and displays it as a pass/fail judgment.


Safety engineered
High-Safety design insulation resistance meter
CAT III, CAT IV rated IR5050 hold the highest standards in safety performance. You may think that insulation resistance measurement is not dangerous because it is performed under power outage conditions, but on the contrary, accidents can be dangerous. The IR5050 have enhanced safety performance in case of such an accident.

Start test: Press and hold for 1 sec. to start measurement. This feature helps prevent inadvertent activation of a high voltage.
To encourage caution, the MEASURE button flashes when a high voltage is being generated or discharged.

Complete: The IR5050 will start discharging automatically as soon as the test is over. During this time, the test start button will flash red to indicate that it is discharging.



Wireless and USB connectivity options for even greater convenience
Wireless support(*1)
*1:The optional Wireless Adapter Z3210 is required.
Installing the Wireless Adapter Z3210 on the instrument enables Bluetooth® wireless communication, facilitating the transfer of measurements to your smartphone or tablet.

Enhance your insulation resistance meter with GENNECT Cross

• A time-series graph of the current provides a visualization of the insulation state of a high-voltage cable. Utilize the logging function of GENNECT Cross to generate time-series graphs of data recorded at one-second intervals, enhancing the analysis and understanding of trends.
• Field Maintenance function: Using a picture of the site, this function can display the measurement values where the measurements are made.
• Report function: Easily create PDF reports with measurement results.

Excel® Direct Input Function
Boost work efficiency in the field by letting you directly transfer measurement data to (i.e., enter measured values directly into) templates created as Excel®.

See details about Wireless Adapter Z3210

Transfer data via USB after measurement
Transfer measured values and logging data saved on the instrument to a PC via USB (*2). This function requires Sequence Maker, a free Excel add-in.

See details about Sequence Maker

*2:DMM Communicator DT4900-01 is required (sold separately).


Rugged protection
Dustproof & waterproof case for outdoor work
The Carrying Case C0212 is a rigid case with IP65 dust and water protection. It provides space for the insulation resistance meter and test leads so that they can be transported easily.
