CWT Weighing Equipment Operation & Calibration 4

Question 1

What is the primary purpose of the 'tare' function on a weighing instrument?

Accepted Answer

To subtract the weight of a container so only the net contents are displayed

Answer

The tare function offsets the display by the weight of an empty container, allowing the scale to show only the net weight of material added afterward.

Question 2

When inspecting a load cell cable for potential errors, a technician should look for all of the following EXCEPT:

Accepted Answer

The cable color matching the platform color

Answer

Cable color has no bearing on performance; pinching, moisture ingress, and shield grounding are all real sources of signal error.

Question 3

A legal-for-trade retail price-computing scale must display price-per-unit and total price. Under NIST Handbook 44, the computed price must be:

Accepted Answer

Accurate within the value of one minimum price increment

Answer

NIST HB 44 requires that computed prices not exceed the value of one minimum price division in error, protecting both buyer and seller.

Question 4

Which action should a CWT technician take if a scale's as-found calibration data shows it was operating outside tolerance at the previous inspection interval?

Accepted Answer

Document the out-of-tolerance condition, assess impact on prior measurements, and report per applicable procedures

Answer

Out-of-tolerance as-found data triggers an impact assessment and nonconformance documentation to evaluate whether prior weighing results were affected.

Question 5

What does OIML stand for in the context of weighing equipment standards?

Accepted Answer

Organisation Internationale de Métrologie Légale

Answer

OIML is the Organisation Internationale de Métrologie Légale, the intergovernmental body that issues international recommendations for legal metrology including weighing instruments.
