Programming the HLPRG SPA
The High Level Input SPA operating parameters are
set, and the settings are stored in on-board, non-
volatile EEPROM. There are four push buttons on the
unit front panel; VIEW, SELECT, an UP arrow, and
a DOWN arrow. Together with the prompting mes-
sages displayed on the LCD, these are used to access
menus, and to view and change the settings for:
•
Select Input Type: current (I) or voltage (V)
•
Select Functional Setting (Linear Mode or Cus-
tom Mode) and, if selected, set Custom Mode
Engineering units.
• Scale Input — Smart Scaling
• Apply Input — Bench Scaling
• Scale Display readout
• Set Linearization Curve (Custom Mode only)
• Scale Analog Output (AO-equipped units only)
•
Trim Analog Output (AO-equipped units only)
•
Configure Alarm Functions (Trip points, etc.)
•

Main Menu/View Settings
Figure 5 gives an overview of the first level of menus
used to configure the SPA.
On power-up, the SPA defaults to a display of the
measured value. Pressing the VIEW button accesses
a series of displays that show, in succession, the set-
tings currently stored in unit memory (see Figure 6).
Depending upon whether or not the Security Jumper
has been installed (see Figure 2), SELECT will access
either the first screen in the main configuration menu,
“SEL V/I”, or the password code query screen, “ENTR
PASS”.
Once the Main Menu has been accessed, the up and
down arrow buttons are used to move through all of
the sub-menus in a loop. Pressing the SELECT button
accesses the first screen of the sub-menu shown on
the LCD.
