Configure Zero and Full Scale —
Smart Ranging
This set of menus is available only on those units
equipped with one of the AO (Analog Output) options.
Referred to as “Smart Ranging”, it allows the user to
program in the values for the analog output’s 0 and
100% settings without having to incorporate the SPA
into any calibration setup.
If a setup is available, the analog output range and
trim can be calibrated using a meter and adjustable
input source. Refer to “Inputting Zero and Full Scale”,
later in this manual. Figure 12 shows the SPA analog
output Smart Ranging menu.
1. From the “CONF Z/FS” screen displayed,
press SELECT.
2. Use the arrow buttons to choose either
“SET ZERO” or “SET FULL”, and press
SELECT.
3. Use the arrow buttons to raise or lower
the value displayed according to the
requirements of the application.
NOTE:
The engineering units displayed on this screen
are determined by the setting entered
in the “CONF OPTS” menu, explained
earlier in this manual.
4. Press SELECT to enter the value into SPA
memory.
5. Repeat steps 2 and 3, if necessary, to set
the complimentary value. Once both have
been set, the “EXIT Z/FS” screen will be
displayed.
6. Press SELECT to go to the Main Menu.
NOTE:
If Smart Ranging is used, the menus for
inputting zero and full scale and the menu for
trimming the output are by-passed. Pressing
SELECT from “EXIT Z/FS” returns to the Main
Menu at “CONF EXIT”.
