Our procedures are to set the Standby Altimeter 'in line' with the Primary Altimeters, i.e. QNH at start-up, and Standard at Transition Altitude during Climb. Where this differs slightly, is that QNH is set for the Standby Altimeter alone at Top of Descent, in advance of Transition Level, where QNH is set on the Primarys.
It's a fairly new SOP, frankly I'd prefer to keep the Standby Altimeter in line with the Primarys at all times.
