Introduction

 

Gauge Checker has been specifically designed as an aid to your 
Equator gauging system. 

Unlike a CMM, the Equator does not need to be re-calibrated 
at periodic intervals, to ensure accuracy across the working 
volume. Equator is regularly ‘re-calibrated’ by nature of the 
mastering process which continually re-establishes an error map 
based on measurement of a known master part. However, it is 
useful to be able to validate that the Equator is working as well 
today as the day it was manufactured. Gauge Checker is a quick 
health-check enabling this to be performed quickly and easily. 

Designed to exercise all of the measurement methods used 
on Equator, Gauge Checker performs a Golden Part Compare 
where the Equator runs a master cycle followed by an immediate 
measure cycle. A report is produced showing deviations from 
nominal for each feature during the measure cycle and these 
deviations are tested against the comparison uncertainty limits 
for each feature.

It is easy to integrate Gauge Checker into your maintenance 
schedule. Each Gauge Checker kit can be used across multiple 
Equator machines. 

Set up is quick, intuitive and easy, using the software wizard as a 
step by step guide.
