5. CONFIGURATION AND CALIBRATION
The A90-SS process panel meter is configured and
calibrated via the four front panel push buttons. All
the configuration functions are contained in an
easy to use intuitive menu that is shown
diagrammatically in Fig 9.
Each menu function is summarised in section 5.1
and includes a reference to more detailed
information. When the meter is fitted with alarms
additional functions are added to the menu which
are described in section 7.3. Similarly when a
4/20mA output is fitted, additional functions appear
in the configuration menu which are described in
section 7.4.
Throughout this manual push buttons are shown
as
( , ) , & and * and legends displayed by
the meter are shown in a seven segment font
exactly as displayed e.g.
CAL
and
ALr2
.
Access to the configuration menu is obtained by
operating the
(
and
)
push buttons
simultaneously. If the meter security code is set to
the default
0000
the first parameter
input
will be
displayed. If a security code other than the default
code
0000
has already been entered, the meter will
display
CodE
. Pressing the
(
button will clear this
prompt allowing each digit of the code to be
entered using the
*
or
&
push button to adjust
the flashing digit and the
(
button to move control
to the next digit. When the correct four digit code
has been entered, pressing
)
will cause the first
parameter
input
to be displayed. If the code is
incorrect, or a button is not pressed within twenty
seconds, the meter will automatically return to the
display mode.
Once within the configuration menu the required
parameter can be reached by scrolling through the
menu using the
*
or
&
push button as shown in
Fig 9. When returning to the display mode
following reconfiguration or recalibration, the meter
will display
dAtA
followed by
5AVE
while the new
information is stored in permanent memory.
CAUTION
When making adjustments in the configuration
menu, if the interval between pressing any
button exceeds one minute, the A90-SS meter
will automatically return to its display mode
and any configuration changes will not be
saved.
All new meters are supplied configured and
calibrated as requested at the time of ordering. If
calibration is not requested, meters will be
