IV.3.2 Time to Torque

Onentrytothismode,theuserispresentedwiththefollowingscreendisplay:

TIMED TO TORQUE

SET TORQUE:00% ↑↓

Figure IV-23

Using the UP or DOWN ARROW keys, the user enters a value for the torque level that you wish to

reach.

Note: The value for torque must be other than zero (0) and less than or

equal to ninety-nine (99) percent or you will not be able to continue.

At this point, the user presses the

OPTIONS/TAB key and the screen shown in Figure IV-24 appears:

TIME TO TORQUE

SELECT RPM: 30 ↑↓

Figure IV-24

Using the UP or DOWN ARROW keys, the user selects a speed from the currently selected speed

set. If you had opted to use the LVRV sequential or interleaved speed sets, all those speeds would

be available by pressing the UP or DOWN ARROW keys. Conversely, if the user had selected a

custom speed set, you would be limited to those speeds comprising the custom speed set. After

selectingthespeed,theusermaypressanyoneofthreekeystocontinue:theOPTIONS/TAB key,

the MOTOR ON/OFF/ESCAPE key and the ENTER/AUTORANGE key. If the user presses the OPTIONS/TAB

key you will return to the torque input screen of Figure IV-23 where you may change the torque

input if so desired. Therefore, continued pressing of the OPTIONS/TAB key will toggle between the

torque input screens and the motor input screen. A press of the MOTOR ON/OFF/ESCAPE key will

cancel the time to torque operation and take the user back to the screen of Figure IV-14. Finally,

pressing the ENTER/AUTORANGE key will cause the DV-II+Pro to accept and store in EEPROM the

new values (only) for the torque level and the selected motor speed.

Thatdone,theuserispresentedwiththefollowingscreen:

TIME TO TORQUE

ENTER TO START

Figure IV-25

At this point the user must press the ENTER/AUTORANGE key to begin the timed stop operation. Any

other key press will be ignored except the MOTOR ON/OFF/ESCAPE key which will cancel the process

and take the user back to the screen of Figure IV-23 where you will have to begin all over again.

We will assume that the user pressed the ENTER/AUTORANGEkey.Youwillnowbepresentedwith

ascreensimilartoFigureIV-26forthedurationofthetimedtorquerun:
