Our company have their verniers calibrated by Mitutoyo. On the calibration certificate, there are a number of characteristics checked.
Are the only characteristics I am interested in as a guide to is the instrument calibrated, the maximum error of reading throughout the measuring range on the imperial and metric scale?
Do I need to worry if the flatness or parallelism of internal/external faces is outside of the requirement? All of our verniers, even 1 which has just been bought new, have some kind of error on the measuring jaws. Is this acceptable from an 'is the instrument within calibration' point of view?
Thanks.

What I was asking was why you're using vernier calipers instead of dial or digital.
