newton meter moment tester torque

an easy way to test torque werench and screw driver.
this method use 100g weight to determine the moment created by the weight.

while using 100g create 0.05-0.2 [NM] , you can use 200g and multiply the moment created since its linear function.

(0.05)*new weight[grams]/100  - (0.2)*new weight[gram]/100 

for example, if you want to test to 2 [Nm] , 1kg weight will give you:

0.05*10-0.2*10 = 0.5 [Nm] - 2[Nm]
