I've only ever calibrated to the closest range im working with which is 7 never had an issue...
"To calibrate the Essentials pH Meter you will need a bottle of Buffer 7 (the meter comes with a small sachet). Then simply dip the meter into the buffer 7 and hold the calibrate button until it says CAL, the Essentials pH Meter will then re-calibrate the device."

Must say I've used HM ,and blue lab ,and the latter been the biggest pile of shit tbh and fuck me way way over priced ..essentials all day long imho
And same as you bud I only calibrate at the one point ( 7)
Also remember 7 is bang in the middle of the ph scale..
