Chapter 1 Introduction
Imported high precision and high stability pressure sensitive
chips are selected for diffused silicon pressure transmitter.
Sensitive chips are fabricated by advanced micro-mechanical
etching process, which forms Wheatstone bridge by diffusing
four high-precision resistors with temperature compensation on
silicon wafers. Because of piezoresistive effect, there are some
changes on the resistance values of the four bridge arm
resistance, so as to make the bridge unbalanced, and then the
sensor outputs an electric signal corresponding to the change
of pressure. The output electric signal is compensated by
amplification and non-linear correction circuit, which generates
voltage and current signals which correspond linearly to the
input pressure.

Chapter 6 Function & Setting(P400)
6.1 Display
The main display area and the sub-display area of the screen
have a variety of display functions.There are three kinds of
display on the main screen, namely pressure value display,
percentage display and current display.The sub-display has
two different options: temperature display and no display.The
temperature value comes from the temperature sensor on the
circuit board, and the display switch can be carried out at any
time. The way each click is displayed depends on the mode
value that the software saved at the end.The display mode set
on the panel will be cleared after the next power failure.

"M"
(1) Press "on" to enter the password setting in the
measurement mode.
(2) Press and hold for 5 seconds in the measurement
mode to enter the principal variable reset (i.e., PV reset).
(3) In the setting mode, press the keys for a second to
enable parameter modification, and the modified
parameter flashes. Press the keys again to confirm
parameter modification, and the modified parameter stops
flickering.
"S"
(1) Press shortly in the measurement mode to modify the
display mode.
(2) Press and hold in the measurement mode for 5

seconds to enter the filling function (the calibration
transmitter is full, which will involve the accuracy and
performance. Do not operate in the case of no standard
source).
(3) In setting mode, add one function for setting
parameters, and long time continuous shift plus one.
"Z"
(1) Press shortly in the measurement mode to modify the
display mode.
(2) Press and hold for 5 seconds in the measurement
mode to enter the zero function (to calibrate the
transmitter zero point).
(3) In the setting mode, for setting parameter
displacement and reduce function, to shift or subtract one
continuously in a long time.
6.3 Monitoring menu
There are two types of access codes, depending on the size of
the transmitter.
(1) 4~20mA output: the entry password is "00001", and the
display unit, display resolution and display mode can be set.
(2) RS485/RS485&4~20mA output: the entry password is
"00016", which can be set as shown in table 1.
Function setting (4~20mA output)
Loc: password input menu, range can be set (19999 ~ 99999),

Set the password to enter the menu. If you enter the
password incorrectly or there is no keys operation within
30 seconds, you will automatically return to the
measurement mode.
Unt: user unit Settings, settable range (0 to 18), menu prompt
for setting each unit.
19 types of unit settings, respectively "MPa", "KPa", "Pa",
"bar", "mbar", "PSI", "mH2O", "mmH2O", "InH2O", "ftH2O",
"mHg", "mmHg", "InHg", "Kg/cm2," "ATM", "Torr", "m", "cm",

Dot: display precision setting, settable range(0 ~ 4), menu
prompt is the current pressure unit
The display resolution is the decimal digits of decimal
places displayed in the measurement mode. Users can set
it according to the requirements of field use. It is not better
to display more decimal places, and the stability of the
display value should be given priority. At the same time,
this menu value will be limited by the maximum transmitter
display value during calibration. If the set number of
decimal points is out of the 5-bit display range when the
maximum display value of the transmitter is displayed, the
set number of decimal points will be limited to the range
where the maximum display value can be displayed
normally.
For example: the calibration range of transmitter is 0.0000 ~
20.000MPa;then the setting range of display precision is (0
