Yokogawa MY600 Specifications

MY600

Digital Insulation Tester

Improve your inspection and regular
maintenance efciency with MY600!

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 testers with a
communication function to enhance the afnity with a PC or tablet.

Major Features

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.

Measurement

PASS FAIL

Judge

Approximately 0.5 s high-speed
measurement*

Measurement time of insulation resistance is approx. 0.5 s,
which contributes to reducing the operation time.

* Under the conditions specied by Yokogawa, it may take time to measure due

to the inuence of capacitive component of a measuring target.

USB communication and memory function

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.

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 1 minute/Resistance after 10 minutes)
DAR: Dielectric Absorption Rate (Resistance after 15 seconds/Resistance after

1 minute)

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 is provided as a
standard accessory

Users can turn measurement on/
off with the hand switch on the
line probe, allowing them work
more efciently.
