[QUOTE="milovisk, post: 163748"] They are cross checked every morning and night with primary standards and are calibrated every 6 months to UKAS standards at a cost probably 10 times that of buying a brand new checkbox. As I quoted above and has been subsequently reiterated in another post "traceabilty to national standards" is the key. Traceabilty is only valid to the length of your certification i.e. 12 months. Cross checking and using non-traceable checkboxes does not fulfill this requirement. [/QUOTE]
