MY600 Digital Insulation Tester

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.

Insulation testing made simpler

  • Featuring enhanced measurement response times of 0.5 seconds and new functionallity for PASS/FAIL Judgement and Polarization Index and Dielectirc Absoprtion Ratio testing
  • Ability to log up to a 1000 data points to internal memory for offline analysis to a PC
  • Automatic LED backlight when working in remote areas with low visibility

Guaranteed reliability for every scenario

  • Large voltage generation and resistance measurement ranges to suit a wide variety of insulaiton types
  • Basic voltage measurement accuracy of +/- 1% of reading and resistance measurement of +/- 2% of reading with the ability to measure up to 4000 MΩ
  • Power off function that minimizes idle time and conserves battery life
  • Built-in auto-ranging for improved resolution at lower resistance levels
  • IP40 Protection Grade for enhanced ruggedness in harsh enviornments

Measurement Functions

  • Wide Insulation Test Voltages: 50V to 1,000 V
  • AC Voltage: 2 Vrms to 600 Vrms (45 to 65 Hz)
  • DC Voltage: +/- 2 to 600 Vdc
  • Low-Resistance: 40.00 to 4,000 Ω

Measurement Accuracy

  • Voltage (AC & DC): 0.1% of reading +/- 4 digits
  • Resistance: ±2.5% reading ±8 digit (0.20 to 4000 Ω) ±8 digit (0.00 to 0.19 Ω)

Other Features

  • Two colors for judging measurement results
  • USB Version 1.1 Compliant
  • Insulation Detioration Diagnosis
  • Automatic LED and Backlight
  • Line probe with switch

 

Two colors for judging measurement results

Set a desired reference value with the comparator function, and it will judge PASS (Green) or FAIL (Red) of a measurement result.

 

Approximately 0.5 s high-speed measurement*

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.

 

USB Version 1.1 Compliant

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.

Insulation deterioration diagnosis (PI and DAR measurement*)

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)

 

Auto lighting backlight and LED light

MY600 has a backlight that automatically lights up in a dark place, as well as an LED light to illuminate objects.

 

Line probe with switch 

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.
