3)
Zero adjusting
pressing and holding the the "
▲
Button " ( 3-5, Fig. 1 ) and
"
▼
Button " ( 3-6, Fig. 1 ) for at least 1.5 seconds to

a.
" P1 input socket " ( 3-9, Fig. 1 ) only
b.
" P2 input socket " ( 3-10, Fig. 1 ) only
c.
Both P1 & P2 input socket
The LCD will show the measuring pressure value.
Note :
*
If the P1 pressure > P2 pressure, the display will
get positive reading.
*
