Measuring Procedure - Lutron Electronics PM-9100HA Operation Manual

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, Kg/cm 2
mm Hg, inch Hg, meter HF2 , inch HF2 , 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 "
( 3-10, 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 " ( 3-10, Fig. 1) to
" P1 input socket " ( 3-7, Fig. 1 ) only
a.
" P2 input socket " ( 3-8, Fig. 1 ) only
b.
Both P1 & P2 input socket
c.
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
