The MY600 Digital Insulation Tester has enhanced operation compared to the conventional model, by using a shortened measurement time and color indicating judging function. This is a new concept in insulation testing and includes enhanced communication to a PC or tablet.
Set a desired reference value with the comparator function, and it will judge PASS (Green) or FAIL (Red) of a measurement result.
The measurement time of insulation resistance is approx. 0.5 s, which contributes to reducing the operation time.
*Under the conditions specified by Yokogawa, it may take time to measure due to the influence of capacitive component of a measuring target.
PC communication is possible with the dedicated USB communication adaptor (91030). Users can save as many as 1000 measurements to the internal memory from which data required for report generation, such as measurement data/time, measured value and range can be transmitted to a PC via communication.
91030 USB communication adaptor （Sold separately）
Driver installation is required to use the 91030 USB communication adaptor.
The increase and decrease of resistance value can be measured by continuously measuring the insulation resistance for a prescribed time. The insulation deterioration of the unit under test can be diagnosed by this increase/ decrease. This parameter is useful for preventive maintenance of industrial automation equipment such as Magnetic Flow Meters or electrical equipment.
*PI: Polarization Index (Resistance after 10 minutes and Resistance after 1 minute)
DAR: Dielectric Absorption Rate (Resistance after 1 minute and Resistance after 15 seconds)
MY600 has a backlight that automatically lights up in a dark place, as well as an LED light to illuminate objects.
Users can turn measurement on/ off with the hand switch on the line probe, allowing them to work more efficiently. This probe is included with the unit.

Preventative maintenance is crucial to maintaining reliable plant operations and reducing costly downtime. As electrical cables are found everywhere in industrial plants, insulaiton testing is one of the many active measures used in this type of periodic equipment validation. Insulation testers ensure the integrity of electrical cables by measuring the quality of the conductivity state. By diagnosing insulation quality early on, you can prevent harmful leakage currents from destroying nearby equipment or harming your personnel.
This application brief goes into how an insulation tester such as the MY600 can be used to maintain the integrity of magnetic flow meters.
