What is the Ndda W55?

Before dissecting "Manual 19," we must understand the base hardware. The Ndda W55 (often stylized as NDDA-W55) is widely recognized as a multi-function process calibrator and HART communicator, typically manufactured by a specialized European or Asian industrial test equipment firm (brands like "Nadda" or similar OEMs are common in this series). Unlocking the Power of Ndda W55 Manual 19:

The W55 is designed to:

Simulate and measure process signals: 4-20 mA loops, 0-10V DC, thermocouples (Types J, K, T), and RTDs (Pt100, Ni120).
Provide 24V loop power for testing transmitters without a separate power supply.
Communicate with smart instruments via a basic HART protocol interface.
Document calibration results for ISO 9001 compliance.

Where this device shines is in the field—oil refineries, power plants, water treatment facilities—where a portable, rugged, battery-operated calibrator is essential. The Ndda W55 is known for its physical durability: a rubber-overmolded case, IP54 dust/splash resistance, and a backlit monochrome LCD that remains readable in direct sunlight.

5. Firmware Update via Infrared Port

Uniquely, the W55 supports firmware updates (from v1.9 to v1.9b, for instance) using a legacy IrDA adapter. Manual 19 lists the exact NEC protocol parameters and error codes (e.g., "Err 19" meaning "IrDA timeout").

Primary Sources:

Manufacturer’s Legacy Portal – Search for the OEM (e.g., "NDDA Instruments" or "W55 support archive"). Look for a section labeled "Discontinued Products" or "Manual Revisions." Many manufacturers maintain FTP directories with filenames like W55_M19_ENG.pdf.
Instrumentation Forums – Communities such as Control.com, MrPLC.com, or the HART Communication Foundation’s legacy board. Use the exact search string: "Ndda W55" "Manual 19" filetype:pdf. Experienced users often upload scans of original paper manuals.
Industrial Auction/Ebay Listings – Sellers of used Ndda W55 units sometimes photograph the manual cover. Contact them and offer $10-$20 for a high-resolution scan of the manual. This is surprisingly effective.
