Mass PT

Sample make/model: RICE LAKE · TW-500

Mass PT

Description

The primary purpose of this PT is to provide an opportunity for participants to demonstrate proficiency in the calibration of a Class F weight set. By participating, participants will demonstrate technical competence for the measurement parameters associated with weights of similar size and weight class.

How this PT is scored

Each reported value is compared with the Lake Balance reference value using the En number, which accounts for both your expanded uncertainty and ours. Results are available in the customer portal. See Scale, balance & mass proficiency testing, all calibration PT programs, and our ISO/IEC 17043 certificate & scope.
