Will they be fitted up for inch pounds?
I thought they always just calibrated to "FT"??
Can your not take it back and change it for one of their Quickset adjustable ones?
Alternatively one of the £20 1/4 square drive adjustable lever type on Amazon or eBay would A) do the job on your stock directly or B) enable you to calibrate your screwdriver....

Most torque drivers that small are pounds/inch or n/cm.
Newton meters also comes with the advantage of not confusing inch lbs with foot lbs...
The equivalents are all easily found on t'internet or calculated...
Any less likely to confuse N/m with N/cm than ft lbs or inch lbs?

It will be a really nice tool I am sure...just geared toward production assembly than jobbing...But should be quite easy top do a basic calibration using another wrench. The cheapest one I linked to would probably be best because that will work anti clockwise for definite...or maybe this one

Just connect the two wrenches at either end of a socket and set and check the torque of your screwdriver against the scale on the other one.
I made my first torque wrench while I was at school using the same principle as the Draper one. It was a tool steel hex section shaft and had a silver steel pointer fixed in the 1/2" square drive head. I calibrated it by gripping the square drive in a vice with the handle horizontal and hung the gym weights of it with a bit wire at 12" along the handle...marking off on the scale with a scriber...put a few A and B series BMC engines back together with that...still around, I saw it in my father's tool box a couple of days ago.
