5. SENSOR TYPE SELECTION

The meter can cooperate with optional 2, 5, 10, 20, 50, 100,

200 bar sensor, new calibration are not necessary when

change the new sensor .

Those different optional pressure sensor are :

* 2 bar pressure sensor, Model : PS100-2BAR

* 5 bar pressure sensor, Model : PS100-5BAR

* 10 bar pressure sensor, Model : PS100-10BAR

* 20 bar pressure sensor, Model : PS100-20BAR

* 50 bar pressure sensor, Model : PS100-50BAR

* 100 bar pressure sensor, Model : PS100-100BAR

* 200 bar pressure sensor, Model : PS100-200BAR

* 400 bar pressure sensor, Model : PS100-400BAR

When change the different sensor ( 2 Bar, 5 Bar, 10 Bar, 20

Bar, 50 Bar...... ) should according procedures as follow :

1) Power off the meter.

2)Use the finger to push the following 3 buttons

at the same time continuously, those buttons are :

* Data Hold Button ( 4-3 Fig. 1 )

* " Max./Min. " Button ( 4-4 Fig. 1 )

* Sensor Type Button ( 4-7 Fig. 1 )

3) Not release the above 3 keys, , push the " Power Button "

( 4-2 , Fig. 1 ) once a while. all the LCD segment will lit.

Release the 3 buttons, the display will show the memorized

sensor type.

Bar

4) Push the " Sensor Type Button " ( 4-7, Fig. 1 ) can select

the different sensor type ( 2, 5, 10, 20, 50, 100, 200, 400 Bar )

Until the display show the desired sensor type, push the

the " Zero button " ( 4-6, Fig. 1 ) to enter the desired

sensor type. The new setting sensor type will memorize

into the circuit even power off.

5)Power off the meter, the sensor type selecting procedures

are finished.

6. MEASURING PROCEDURE

1)Plug in the " Plug of Pressure Sensor " ( 4-13, Fig. 1 ) to

meter's " Sensor Input Socket " ( 4-9, Fig. 1 )

2)Power on the meter by push the " Power Button " ( 4-2,

Fig. 1 )

3)Push the " Sensor Type Button " ( 4-7, Fig 1 ) to check if

the meter's sensor type is same as the external pressure senso

4)Push the " Unit Button " ( 4-5, Fig. 1 ) to select the unit (

Bar, Psi, Kg/cm 2 mm/Hg, inch/Hg, meter/HF2 ,　　

inch/HF2 , Atmosphere ).　

5)Zero the meter by push the " Zero Button " ( 4-6, Fig. 1 ),

the display reading will change to zero value.

6) Connect the " Port Connector of Pressure Sensor "

( 4-11, Fig. 1 ) to the installation that intend to measure

the pressure value that into the sensor.

7)Apply the pressure, pressure meter will show the pressure

value.

8)Data Hold

During the measurement, pushing the " Data Hold

Button " ( 4-3, Fig. 1 ) will freeze the measured value &

display will indicate " HOLD " symbol.

* Push the "Data Hold Button" again to release the

data hold function.

9) 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 " ( 4-4, Fig. 1 )

once. " REC " symbol will appear on the LCD display.
