Ectron 451, Инструкция по эксплуатации

Страница: 26 / 74

Model 451 that would be produced if the dialed-in displacement were at the input of Model
451, taking gain, transducer sensitivity, and unit of measure currently active into account.
Pressing the
CAL
screen brings the user to the cal setup menu.
Cal Volts
Selecting this screen takes the user to the
CALOFF
NN.NN VOLTS screen. position. Enter any voltage
from
−
10.00 to +10.00 V and change
OFF
to
ON
. (Be-
cause of space restrictions on the screen, CALOFF is
written as one word but in fact, the
OFF
part is change-
able to ON by rotating the encoder.) While cal is ON ,
pressing the display has no effect. Only when cal is
turned
OFF can one return to the CAL VOLT screen.
The selected cal voltage will remain in nonvolatile ram.
Cal Displacement
Selecting this screen takes the user to the
CALOFF

screen (
***
equals the current unit of dis-
placement; i.e.,
DEG
,
MIL
, or
MM
). Enter the desired
displacement 10000 to +10000 mils, 254.0 to +254.0
mm, or 60.00 to +60.00 deg) and turn
OFF
to
ON
.
(Because of space restrictions on the screen,
CALOFF
is written as one word but in fact, the
OFF
part is
changeable to
ON
by rotating the encoder.) While cal
is
ON
, pressing the display has no effect. Only when cal is
turned OFF can one return to the CAL DISP screen. The
selected cal displacement will remain in nonvolatile ram.
Cal Exit Pressing the display, at this screen, returns the user to
the main-menu (
CAL
).
OTHER
This main-menu selection takes the user to the secondary menu.
SECONDARY MENU (Figure 3-3)
The secondary menu consists of five additional menus plus an exit screen to return to the
main menu. The Model 451 is configured this way to prevent accidental change of parameters
that are changed less frequently during its operation. Included on the secondary menu are
excitation setup (
EXCIT SETUP
), units of measure (
UNITS OF MEASUR
), system reset
( RESET SYSTEM ), alignment ( ALIGN ), system information ( SYSTEM INFO ), and exit
to the main menu ( OTHER EXIT ).
EXCITATION SETUP
In the excitation-setup menu, the user can select both the excitation voltage and the excitation
frequency. From
EXCIT SETUP
, press the display to go to excitation voltage setup (
EXCIT
VOLTS SETUP
).
Excitation Voltage Setup
From this screen press the display, select either 1 V ac
or 3 V ac as the excitation voltage, and press the display
to accept that setting. Excitation voltage is in real time
meaning that the voltage will change from 1 V ac to
3 V ac or vice versa as soon as the encoder is turned.
