For this Scuba II from Lovibond, you will need to carry out a zero calibration for the first use.  When you activate the Scuba 2 digital tester for the first time, it will request this initial zero calibration measurement. You only need to do this once as long as the tester remains switched on, unless you wish to test the quality of other water.
