(or gain) at which the Model 451 operates. If the core moves beyond Point 2 or if it moves
in the opposite direction, the Model 451 will continue to provide accurate data as long as
built-in limits of the Model 451, such as 10.5 V output, and the LVDT (displacement range)
are not violated.
When the example mode is not active, the user will encounter a screen that asks whether
to activate this mode. If the user answers
NO
, the
EXAMPL MODE SETUP
screen is
again displayed. When the example mode is the active mode, this screen is not displayed.
When the users answers
YES to activating the example mode or when the example mode
is already active, the example-setup menu is displayed.
Example Point 1 Volts Press this screen to go to Point 1 volts input. Then use
the encoder to enter any voltage between
−
10.00 V and
+10.00 V, and answer Y (yes) to confirm the setting or
N
(no) to return to the previous screen without changing
the setting. When Y is on, “ time out” is will not occur.
Example Point 2 Volts Press this screen to go to Point 2 volts input. Then use
the encoder to enter any voltage between 10.00 V and
+10.00 V but not the same as the Point 1 voltage setting.
As with Point 1, answer
Y
(yes) to confirm the setting
or N (no) to return to the previous screen without having
made the change. When
Y
is on, “ time out” is will not
occur.
Example Point 1
Displacement
Press this screen to go to Point 1 displacement input.
Then physically put the LVDT core or what the core is
attached to the desired position, answer
Y (yes), and
press the display to capture the position of the LVDT
core as Point 1. This point must be physically different
than Point 2. If
N
(no) is selected, the display will return
to EXAMPL POINT1 DISP . When Y is on, “ time
out” will not occur.
Example Point 2 Displace-
ment
Press this screen to go to Point 2 displacement input.
Then physically put the LVDT core or what the core is
attached to the desired position, answer
Y
(yes), and
press the display to capture the position of the LVDT
core as Point 2. This point must be physically different
than Point 1. If
N (no) is selected, the display will return
to
EXAMPL POINT2 DISP
. When
Y
is on, “ time
out” will not occur.
Example Mode Transducer
Sensitivity
Selecting this screen allows the user to enter the
transducer sensitivity that is associated with the particu-
lar LVDT or RVDT transducer being used. The valid
range of numbers that can be entered depend on what
unit of measure is currently active. See Table 3-2.
Example Mode Exit By pressing the display at this screen, the user returns
to
EXAMPL MODE SETUP
.
