When ordering several scales please specify under "remark" which ones require a certificate.
Issue of Test Certificates for PESOLA Hanging Scales with capacities of 100 - 200kg (new or used) Ordering a new PESOLA scale you may at the same time request the optional test certificate. For scales once delivered, PESOLA can only issue test certificates when they are sent back to the PESOLA factory. For reasons of safety and quality management it is not possible to hand in certificates for scales with hindsight without again testing them in our factory. Due to a double control-process of every single scale, you can rely on the general indication of high precision and tight tolerances listed on the product detail pages of our Homepage even without a test certificate.
Description of the Test Process at the PESOLA Factory
We check the batteries and replace them if necessary.
We acclimate the scale for about 1 hour at 20±1°C.
The correct function of the scale is tested. Used scales with defects are repaired (cleaning, repair, adjustment, function control). Should we have to replace expensive components they will have to be invoiced separately.
A sticker with an individual certification number is attached to the scale (if not existing already).
We proceed according to the manual for "user calibration". Digital hanging scales are solely tested vertically with M1 hook weights.
The result of the ± measuring tolerance is documented.
The certificate is established with the individual certification number and enclosed to the scale. In this document we recommend a certain test cycle. According to intensity of use the customers may define their own quality test and certification cycle.
