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 "

( 3-11, 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

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

" P2 input socket " ( 3-8, Fig. 1 ) only

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. 5

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.

" MAX./MIN. Button " continuously for at least 2

seconds. The display will revert to the current reading.

8)For quick measurement, follow the procedures

shown below :

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

(3.5 mm jack plug) (9W 'D" Connector)

Ground/shield................................Pin 5

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 :

D0 End Word

D1 to D8 Display readin

For example : If the display readin

is 1234, the

D8 to D1 is 0000123

D9 Decimal Point ( DP ) for Upper display.

0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP

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.
