Product configuration
The core configuration concerns oxygen or humidity measurement display, calibration and diagnostics in a ZR22/ZR402 system. For ZR402G-M-E-E-A, check what is supplied in the ordered build and what belongs to the surrounding system. Compare ZR402G-M-E-E-A with the current nameplate, drawings and the manufacturer specification whenever an option code affects compatibility. Document the selected range, connection and signal path before treating another model as a substitute.
Verification notes
Before installation, verify converter-to-detector compatibility, output, supply, display settings and replacement support. Record the as-found configuration for ZR402G-M-E-E-A, then test the relevant input, output, indication or measurement after work is complete. Keep the exact model ZR402G-M-E-E-A in the work order and final equipment record so future service can identify the installed build without guessing from the family name.
Lifecycle and replacement
The manufacturer identifies this product family as discontinued or part of a discontinued system. Confirm stock, support and any approved replacement before specifying ZR402G-M-E-E-A. Legacy status does not establish that a newer unit is a direct drop-in substitute for ZR402G-M-E-E-A; review mechanical and electrical compatibility separately.
