Answer

NIST Handbook 44 (Specifications, Tolerances, and Other Technical Requirements for Weighing and Measuring Devices) is the primary US standard for commercial device tolerances.

Question 2

A newly installed hopper scale at a grain elevator shows erratic readings during wind gusts. The primary safety and compliance concern is:

Accepted Answer

Wind-induced measurement errors affecting commercial transactions

Answer

Wind can introduce force errors in suspended hopper scales, causing inaccurate measurements that affect the integrity of commercial transactions.

Question 3

When must a service technician re-seal a weighing device after performing repairs?

Accepted Answer

After any adjustment or repair that could affect metrological performance

Answer

Any adjustment or repair that may affect the accuracy of a commercial device requires re-sealing to maintain the integrity of the device's certification.

Question 4

A vehicle scale technician notices hydraulic fluid pooling beneath a hydraulic scale platform. The immediate safety action is to:

Accepted Answer

Stop testing, barricade the area, and address the hydraulic leak before continuing

Answer

Hydraulic fluid creates slip hazards and fire risks; the area must be secured and the leak addressed before safe operations can resume.

Question 5

Which grounding requirement is most important for preventing static discharge when calibrating a livestock scale?

Accepted Answer

The scale frame must be bonded to an earth ground to prevent static buildup

Answer

Proper bonding and grounding of the scale frame prevents static discharge that can damage electronics and create shock hazards in dry environments.
