4. MEASURING PROCEDURE

1) Power on the meter by pressing the " Power Off/On

Button " ( 3-2, Fig. 1 ).

2) Select the desired temperature units ( mbar, psi, 

mm Hg, inch Hg, meter       , inch        , Atmosphere )
by pushing the " Unit Button " ( 3-6, Fig. 1 ).

3) Zero adjusting

Adjust the display reading to zero value by pushing 
the " Zero Button " ( 3-4, Fig. 1 )

4) Install the measuring pipe to " Plug/quick coupler "

( 3-11, Fig. 1 ).

5) The meter is build the two input socket ( P1 input socket,

P2 input socket) for accepting the differential pressure
input. 
Connecting the pipe along the " Plug " ( 3-11, Fig. 1) to 

a.

" P1 input socket " ( 3-7, Fig. 1 ) only

b.

" P2 input socket " ( 3-8, 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.

 * If the P1 pressure < P2 pressure, the display will  

get negative reading.

6) Data Hold
 * During the measurement, pressing the " Hold Button "

( 3-3, Fig. 1 ) will freeze the measured value & the LCD
will show " HOLD " symbol.

 * Press the " Hold Button " again to cancel the data hold

function.
