EXPLANATION PROGRAMMING POINTS
6.1
ZERO ADJUSTMENT (ZERO, 4 mA)
The transmitter is set to 0 mbar at atmospheric pressure.
The
ZERO
can be adjusted at a lower or higher point. This will be
explained step by step by an example.
Example: Increase ZERO till 100 mBar.
6.
The measuring unit of the transmitter is set to mBar. If not this can be selected by choosing
the right measuring unit in program point
1.04 – UNITS (paragraph 6.4)
7.
Navigate to program point
P101 - ZERO Value
, and push the navigation button to enter the
menu.
8.
Two choices appear on the screen: “
set manual
” and “
use process
”
Set manual
= Configuration without test pressure.
Use process
= Configuration with applied pressure.
9.
Choose “
set manual
”, +000.0 (mBar) will appear on the display.
10.
Increase this value with the navigation button to 100 mBar, push to confirm, and select
to save the setting.
11.
The transmitter will return to the home screen. The measurement value at atmospheric
pressure is now -100 mBar. At an applied pressure of 100 mbar the transmitter will display 0
mbar.
The menu zero adjustment also has the choice of “
use process
”. The transmitter can be adjusted to
zero in a real process situation. When chosen, the transmitter will measure the pressure in an actual
process. This measurement will be used as the zero value. (4 mA)
4.
Navigate to program point
P101
, and push the button to enter the menu.
5.
Choose “
use process
” , and push to confirm. The transmitter will display the actual measured value.
6.
Push the navigation button to confirm, and select
to save the setting.
7.
The transmitter will return to the main menu.
6.2
SPAN ADJUSTMENT (SPAN, 20 mA)
This setting can be used to adjust the range (SPAN) according to an
entered value or adjusted with or without an applied pressure. The
maximum pressure which can be measured (20 mA) is the measurement at
ZERO (1.01)
+ the entered value
SPAN (1.02)
. If the
ZERO (1.01)
is increased then the
maximum measured value will automatically be set higher at same rate like the zero.
This will be explained step by step by an example.
Example: Measurement range 0 – 2000 mbar = 4 - 20 mA.
The
span
must be set at 2000 mbar
5.
Navigate to program point
1.02 - SPAN Value
, and push the navigation button to enter the menu.
6.
Two choices appear on the screen:
Set manual
and
Use process
Choose
Set manual
, a value will appear on the screen. (Depending on the range.)
7.
Adjust the
SPAN
with
the navigation button to 2000 mbar. and select
to save the setting
8.
The transmitter will return to the home screen.
