CIS is mounted. The 12-inch arm accessory has the largest load (bending moment) among all arm 
accessories recognized by Mindray, with a maximum load of 13.6 kg. Therefore, the force can be 
calculated as follows: 
Wmax = 13.6 kg × 304.8 mm = 4150 kgf.mm (30 lbf ft) 
L (mm): maximum arm length 
M (kg): load
