How To Use Insulation Resistance Testers Hioki Before measurement, perform zero adjustment to cancel the test leads’ wiring resistance and other potentially problematic quantities. ・ set the rotary selector to the Ω function. ・ short circuit the tip of the test lead. ・ pull up the measure key. ・ turn off the measure key to hold the measured value. ・ press the “0Ω adj” key. This video explains how to use a digital insulation resistance tester to measure a distribution panel. ※ shooting was done with japanese model ir 4052. the global model name is ir 4057. insulation resistance tester product list.
How To Use Insulation Resistance Testers Hioki Hioki insulation resistance testers or megohmmeters feature all in one designs including built in rugged cases and test lead storage compartments. the ir4056. Page 4: introduction. introduction introduction thank you for purchasing the hioki model ir4051, ir4052, ir4053 insulation tester. to obtain maximum performance from the instrument, please read this manual first, and keep it handy for future reference. the “instrument” in this manual means ir4051, ir4052, or ir4053. Page 25: measuring insulation resistance 2.4 insulation resistance measurement 2.4.2 measuring insulation resistance always turn off the breaker of the measurement line. source (primary side) load (secondary side) ex. when measuring the insulation resistance between circuit and ground if the measure key is in the raised position, push it down. Excluding ir4056 21. 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.
