Type
Y<Enter>
to accept the calibration values or
N<Enter>
to reject them.
Note:
The last calibration scan data is saved in the file
MOTOR_TY.DAT
. You can reanalyze
the data–e.g., after editing
hardware.ini
–by typing the command
CALIBRATE
@MOTOR_TY.DAT
at the MOTOR$TY> prompt in SQDRIVER.EXE.
MOTOR$TX (all QDR 4500 models)
Before beginning this procedure, make sure that the TX motor encoder
is not
secured to the
drive shaft and that the tank assembly is not under the operator console.
1.
Select the TX motor device driver by typing
MOTOR$TX<Enter>
2.
Then, at the MOTOR$TX> prompt in SQDRIVER.EXE, type:
CALIBRATE<Enter>
The program prompts
Press <ESC> to stop calibration.
The program moves the TY and AY motors to their center positions, then moves the TZ
motor to its topmost position and prompts:
Use the Table IN / OUT switch to move the C-Arm to 0 degrees.
Press <Enter> when the C-Arm is positioned.
Press <ESC> to stop calibration.
The above message is always displayed when calibrating MOTOR$TX. This is normal. For
QDR 4500W and QDR 4500C systems, press <Enter> to continue.
For QDR 4500A and QDR 4500SL systems, place the digital level on top of the C-arm and
use the Table IN/OUT switch on the operator panel to move the C-arm until it is level
(±0.1º). It is not necessary for this procedure that the C-arm be
exactly
level, only that it is
sufficiently close that subsequent relative rotations do not hit the table).

Remove the level and then press
<Enter>
. The program prompts:
Press <Enter> when the TX motor reaches the OUTER mechanical limit.
Press <ESC> to stop calibration.
When TX hits the outer mechanical stop the first time,

The program returns to the MOTOR$TX menu page (below). In the right hand column of
the display, eight lines from the bottom (and highlighted in the figure below), is the raw a/d
