Pitch is the centre-to-centre distance between array elements — the sum of element width and kerf. It is not the number that sets resolution. It is the number that decides how far a beam can be steered before a second, equally strong lobe appears somewhere it was not aimed.
The VIVID E9 service manual prints the same first remedy for a touch panel that activates the wrong control and for one that stops answering. What the calibration dialog moves, where the system's other calibration lives, and what the escalation order is really covering.
A TEE probe's bending section cannot report its own condition, and some current models publish no deflection range to compare it against. What each class of document can settle — and the baseline you have to record yourself.
A specification sheet interleaves two kinds of fact and presents them in the same format: what the instrument is, and which version of it you have. This is how the parameters group, where the design trade-offs are documented, and where the category boundaries actually fall.
A flexible endoscope can pass its leak test and still be holding liquid. The test asks whether air escapes; it does not ask whether water got in. This is how the two answers come apart, where the liquid goes next, and the one step that cannot be undone.
A pediatric phased array probe datasheet cannot tell you whether your console supports it. Console generation, CW hardware, software revision, and preset assignment decide that, and none of them are written on the probe.
