Flash Power Selection / Indication The Flash Power Selector Switch (Fig 2) sets the maximum flash power available. The power selected, 500, 1000 or 1500 Ws, is shown on the Digital Power Display (Fig. 2) and represents a coarse control range of 11/2 f-stops. The Flash Power Control (Fig. 2) provides a continuous adjustment within the range selected, over a five f-stop range from full to one thirty second (1/32) power. Rotating the Flash Power Control (Fig. 2) from full to half, half to quarter, quarter to eighth, eighth to sixteenth and sixteenth to thirty second gives a reduction in output equivalent to 1 f-stop for each step. The total control range using the Flash Power Control and Flash Power Selector Switch is 61/2 f-stops.
