As a quick and dirty guesstimate, try drawing the largest spark you can 
between the secondary leads. Then figure approximately 20kv/in of spark. 
Next, check the power rating of the zapper, usually 35W-150W on the label or 
on the box. Figure I~ P/E. With these ballpark numbers, you can select  the 
proper meters/dividers to do fine-tune measurement.
