The catalog's general linearity figure and the diameter-specific errors are separate specifications. Use the error for the selected probe; do not apply the single general figure to every range. The original heading translated here as minimum target dimension has unclear terminology; confirm its meaning before specifying a target surface.
Probe ordering options

| C — Output | 01: 4–20 mA; 02: −2 to −18 V; 03: 0–5 V; 04: other output |
Only the printed codes are listed. An ellipsis in the catalog does not establish the omitted intermediate ordering codes.
Selection drawing and limitations
The selection drawing identifies the probe, probe cable, extension cable and armor by the ordering-table letters. It does not specify additional universal fixed dimensions. The conditioner designation is printed as CWY-DO; whether the final character is the letter O or the digit zero remains unconfirmed. The YD9800 drawing also identifies the wrench flats and separate probe-cable and extension-cable portions of F.
