Zero Setting Mechanisms: Do the semi-automatic zero setting mechanism(SAZSM) and automatic zero tracking (AZT) work correctly and meet requirements?
Tare Mechanisms: Pushbutton, percentage, proportional, and PLU linked, will all be evaluated to make sure they oper - ate in the correct manner.
Indication and Registration: Does the instrument have the weighing units marked, do the annunciators for motion, stability, and center of zero if equipped work correctly, and does the unit conversion key work correctly if equipped? Is the printed label or tape format correct with the weight values identified? Optional Features: NTEP looks at all instrument features when a device is evaluated even if there is no metrologi - cal significance to the feature. Here are some examples, Wireless communication (wi-fi, Blue - tooth) Power supplies (Solar, battery, POE), platter types ( roller ball, conveyor), remote displays (pedestal, pole mounted, remote to PC and mobile devices). Different types of materials used for construction (mild steel, stainless steel, plastic) types of displays ( LED, VGA, or LCD), enclosure mounting types,(Din, panel, wall, or desk mount ) external printing capability, and many more.
