Vascar

[BMC]

Does anybody know the rules on how regularly Vascar has to be calibrated. A friend has recently been stopped and we were both under the impression that the calibration needs to be certified daily, but he was told by the officer that they only do this on a weekly basis.
Can anybody shed any light?

Thanks
