Insulation-maintenance measurement planning with Yokogawa MY600
The complete designation MY600 identifies a digital insulation resistance tester. Use the full code when requesting a quotation or reviewing a spare. Selection of Yokogawa MY600 should account for the process or system interface, the supplied configuration and the records needed to support installation and future maintenance.

Choose the test for the asset
MY600 is intended for insulation-resistance testing with selectable test voltages. The voltage and duration must follow the equipment requirements and the approved maintenance method. For MY600, identify the asset, its condition and any connected components before selecting a test; a higher test voltage is not automatically the appropriate choice for every installation.
Make trend readings comparable
Insulation readings taken with MY600 should be linked to test duration, temperature and the asset identification. PI or DAR results should be interpreted using the relevant maintenance criteria for the equipment. When recording a result from MY600, retain the test settings and conditions so a later reading can be compared on a meaningful basis rather than treated as an isolated resistance number.
Inspect the instrument and accessories
Before using MY600, check the leads, connectors, battery condition and calibration status in accordance with the instrument procedure. The equipment under test must be prepared by qualified personnel using the appropriate isolation and discharge arrangements. For procurement of MY600, clarify the included accessories and documentation, then establish how stored readings will be transferred into the asset-maintenance record.
- Equipment-specific test voltage and duration
- Isolation, discharge and access procedure
- Lead condition and calibration status
- Asset tags, stored readings and reporting method
Define the measurement package
A test-instrument enquiry should identify the required functions, working ranges, accessories and calibration documentation. Specify the circuit or asset being tested and how the result will be recorded. Inspect the supplied leads and connections against the instrument instructions before use. Retain the instrument identification, test settings and measurement-chain details with the reported data so later comparisons use an equivalent setup and an appropriate level of traceability. Preserve the exact MY600 designation on the enquiry and confirm the offered MY600 configuration before release.
Enquiry and receiving checks
An enquiry for MY600 is more useful when it includes the equipment tag, intended application and the reason for replacement or new purchase. Add the current configuration record and the delivery documentation required by the project. Before releasing MY600 for installation, compare the supplied nameplate and package contents with the agreed order, then retain the confirmation with the commissioning information.
