2. How to check the air conditioning system with the needle of high low gauge
To connect with manifold pressure gauge can nd the cause of air conditioning system.
Because manifold pressure gauge is various sensibly. (Ambient Temp. is based on 30~35℃)
3. Gauge pressure conversion

lb/in²=PSI

1 kgf/㎠=14.22 lb/in² (Ex) 200 PSI=14 kgf/㎠
Operating E/G RPM 1500~2000 is must, and so to that you can check the correct cause and air conditioning. (In case be-
low the gure of indicated pressure gauge has some clearance, conrm with approximate indicated needle data.)
