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.

7)Data Record ( Maximum, Minimum reading )
* The DATA RECORD function displays the maximum
and minimum readings. To start the DATA RECORD
function, press the " MAX./MIN. Button " ( 3-5, Fig. 1 )
once. " REC " symbol will appear on the LCD display.
* With the " REC " symbol on the display :
(a) Press the " MAX./MIN. Button " ( 3-5, Fig. 1 )
once, the " Max " symbol along with the maximum
value will appear on the display.
(b) Press the " MAX./MIN. Button " again, the " Min "
symbol along with the minimum value will appear
on the display.
(c) To exit the memory record function, press the
" MAX./MIN. Button " continuously for at least 2
seconds. The display will revert to the current reading.

5. AUTO POWER OFF DISABLE
The instrument has built-in " Auto Power Shut-off " in
order to prolong battery life. The meter will switch off
automatically if none of the buttons are pressed within 10
min.
To de-activate this feature, Select the memory record
function during measurement, by pressing the " MAX./MIN.
Button " ( 3-5, Fig. 1 ).
6. RS232 PC SERIAL INTERFACE
The instrument features an RS232 output via 3.5 mm
Terminal ( 3-9, Fig. 1 ).
The connector output is a 16 digit data stream which
can be utilized to the user's specific application.
An RS232 lead with the following connection will
be required to link the instrument with the PC
serial input.
Meter PC

The 16 digit data stream will be displayed in the
following format :
D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
Each digit indicate the following status :
D15 Start Word
D14 4
D13 1
D12 & D11 Annunciator for Upper Display
mbar = 86 psi = 23
mm Hg = 78 inch Hg = 80
inch H20 = 25 Kg/cm^2 = 77
Atmosphere = 26 meter H20= 79
D10 Polarity 0 = Positive 1 = Negative
D9 Decimal Point ( DP ) for Upper display.
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP
D1 to D8 Display reading, D1=LSD, D8=MSD
For example : If the display reading is 1234, then
D8 to D1 is 00001234
D0 End Word

Baud rate 9600
Parity No parity
Data bit no. 8 Data bits
Stop bit 1 Stop bit
7. BATTERY REPLACEMENT
1)When the left corner of LCD display show " LBT ",
it is necessary to replace the battery. However,
in-spec measurement may still be made for several
hours after low battery indicator appears before the
instrument become inaccurate.
2)Slide the Battery Cover ( 3-10, Fig. 1) away from the
instrument and remove the battery.
3)Install a 9 V battery (PP3 type) and replace the cover.
