Found no objective evident of certificate of calibration for primary instrument of Digital Static Mete use for verification purposes.
Objective evident:
Based on QC Flow chart SD QA 001 N2 on production defined that during Coating process 1 st stage (9) and Laminate (10.1) need to monitor the electrostatic properties of product by using Digital Static Meter DSM 01, 02 and 03 in which according Equipment calibration plan 2016 defined that need to verify every 2 months but found no objective evident of primary standard of Digital Static Meter to ensure the correctness of verification result passed the defined verification criteria
