7.5 Data Entry
When there is a requirement to enter specific numeric or alpha values into the system, the
method of entry is consistent for all instances. When a
[VALUE ENTRY] key is pressed a
dialog box will appear similar to "Figure - Value Entry". This Value Entry dialog box will have
a numeric or alpha keypad, when appropriate minimum and maximum value limits, current
value and a window that shows the new value entered. The value can be deleted completely
using the
[DELETE] key, the last digit of the entered setpoint can be deleted using the
[CLEAR ENTRY] key or the setpoint value can be accepted using the [ACCEPT ENTRY]
key.
7.6 Pressure unit, Pressure mode and Emulation mode
The Pressure [UNIT] key is shown on the main screen below the current pressure value and
displays the most recently chosen pressure units and the mode (absolute or gauge). If the
optional barometric reference is installed a
[MODE] key replaces the mode indication to the
right of the units key. This [MODE] key indicates absolute or gauge mode. When the key is
pressed it will switch between the "native mode" of the internal sensor to the emulation mode.
The "native mode" is the mode of the sensor that is installed and is either absolute or gauge.
Emulation mode uses the value of the barometric reference to emulate the mode that is alter-
nate to the native mode. The CPC3000 can emulate gauge from a native absolute sensor or
absolute from a native gauge sensor. The
[MODE] key indicates the native mode with a blue
key background and emulation mode with a light blue key background. The units and mode
chosen remain the same when the CPC3000 is turned off then back on.
Pressing the [UNITS] Key will open a dialog box that shows the available pressure units with
a tabs for [ENGLISH], [METRIC] and [USER UNITS] units. Pressing a tab will open a menu
with the related set of units available. The [USER UNITS] tab menu includes [USER 1] and
[USER 2] keys and allows the user to enter customized pressure units. Press the [MULTIPLI-
ER VALUE] key to enter a multiplier that defines the user unit as the multiplier times one psi
or one Pascal, whichever is currently pressed.
