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

r

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.

8

* With the " REC " symbol on the display :

(a) Push the " Max./Min. Button " ( 4-4, Fig. 1 )
once, the " Max " symbol along with the maximum
value will appear on the display.
(b) Push 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, push the
" Max./Min. " button continuously at least 2 seconds.
The display will revert back to the current reading.

10 ) For quick measurement, follow the procedures

shown below :

Main procedures :

Connect the " Sensor Plug " to the meter's " Input Socket ".

Power on the meter & select the display unit.

Zero the meter by push the " Zero Button ".

Connect the pressure sensor connector to the measuring
installation

Apply the pressure, meter will display the pressure value.

Optional measuring procedures :

DATA HOLD MEMORY RECORD RS232 OUTPUT

Max., Min.

Power management :

AUTO POWER OFF or MANUAL POWER OFF
(Not activated during
Memory Record Selection)

11) Measuring considerations :

*

The sensor diaphragm can be damaged by solid or
sharp objects. Never insert any object into the inlet
port.

*

The pressure sensor is compatible with industrial gases
& liquid that are compatible with the 316 stainless steel
or ceramic material. To determine the compatibility of
a liquid or gas, refer to manufacture's specification.

7. AUTO POWER 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 ( 4-4, fig. 1 ).

10

8. CALIBRATION

Each meter already adjust & calibrate according the
condition for the 100 mV signal input to let the display
reading full scale & 0 mV input signal to let the meter
reading zero value.

Each optional pressure sensor ( PS100-XXBAR ) are
designed to meet the 100 mV output to let meter show
the full scale value & the 0 mV output signal for the
meter to read zero value.

General speaking it is not necessary to make any new
calibration procedures both of pressure meter & the
the external pressure sensor due to those two units
already done the well calibration typically.

Due to the environment temperature may drift seriously or

after a long time operation....., the meter's zero & gain

( span ) value may drift. If intend to make the measurement
precisely, it can make the new calibration as :

8-1 Zero calibration

1)Connect the meter with the pressure sensor, power on the

meter. No pressure signal into the sensor.

2)At the same time hold the following two button continuously .

" Hold Button " ( 4-3, Fig. 1 )
" Max./Min. Button " ( 4-4, Fig. 1 )

11

The LCD will show the zero value on both up & down display.

For example :

Bar

.

0.03

3)Still hold the " Hold Button " & the " Max./Min. Button ",

at same time push the " Zero Button " ( 4-6, Fig. 1 ) once
a while, the display will flash one time & return to zero as :

Bar

.

0.00

4)Release both of the " Hold Button " & the " Max./Min.

Button ", then power off. Now the new zero value will
memorize to the circuit automatically.

8-2 Gain calibration ( Span adjust )

1)Set up the whole meter system are ready measurement,

refer the above " 6. MEASURING PROCEDURES ".
Turn on the meter and allow it to warm up for two minutes.
Should zero the meter by push the " Zero Button ".

12

2)Connect the pressure regulator to the nitrogen bottle

and the reference gauge to the pressure regulator.
The pressure regulator should can generate the full scale
pressure value.

For example, input a standard 9.00 pressure value to the
the sensor, the display show 8.98 Bar.

3)At the same time hold the following two button continuously .

" Hold Button " ( 4-3, Fig. 1 )
" Max./Min. Button " ( 4-4, Fig. 1 )

The display show the measuring value on both up & down
display.

For example :

Bar

.

8.98

4)Still hold the " Hold Button " & the " Max./Min. Button ",

at same time.

*

Push the " Sensor Type Button " ( 4-7, Fig. 1 ) once
will add one count to the down display value.

*

Push the " Unit Button " ( 4-5, Fig. 1 ) once will decrease
one count to the down display value.

13

Bar

.

9.00

5)Until the desired regulating value ( for example 9.00 ) be

adjusted, release both of the " Hold Button " & the
" Max./Min. Button " at same time.
Now the display flash, within 5 second should push the
" Sensor Type Button " ( 4-7, Fig. 1 ). Now the new gain
value will memorize into the circuit.

9. RS232 PC SERIAL INTERFACE

The instrument features an RS232 output via 3.5 mm
Terminal ( 4-10, 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 :

D0 End Word
D1 & D8 Display reading, D1 = LSD, D8 = MSD

For example :

If the display reading is 1234, then D8 to D1 is :

00001234

D9 Decimal Point(DP), position from right to the left

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

D10 Polarity

0 = Positive 1 = Negative

10. BATTERY REPLACEMEN

T

1)When the left corner of LCD display show "LBT",

it indicate a normal battery output of less than 6.5 V -

7.5 V. 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( 4-8, Fig. 1 ) away from the

instrument and remove the battery.

3)Install a 9 V battery ( heavy duty ) and replace the cover.
