5.2-2 Section 5: Using the Model 9100 — Procedure Mode: Safety and General Notes
5.2.3 Serial Mouse
A serial mouse can be used to improve the speed of user-interaction in Procedure mode
only.
Data are transferred between the mouse and 9100, providing rapid selections within
certain operations of Procedure mode.
The mouse can also be used to slew the output in the 1 Year Verification procedure,
and possibly in other user-programmed procedures
5.2.3.1 General Use of a Mouse
Buttons
Within Procedure mode it is advantageous to move rapidly between procedure screens.
The two screen keys at the extreme left of the bottom row are often used to transfer from
one procedure screen to another (one for 'OK' or 'PASS'; the other for 'FAIL').
The left and right buttons of a mouse duplicate the operation of these two screen keys.
Other buttons or wheels are not used. Whenever it is necessary to press either of these
screen keys, the two mouse buttons will perform the same actions.
Left - Right Mouse Movement
Movement of the serial mouse left or right is summed and mapped to the
and keys.
Some of the Procedure mode screens offer a list of user-choices.
Moving a mouse left
or right will move the highlight up and down such lists, changing the selection; then
pressing the left button (equivalent to 'OK' on the screen key) will confirm the selection,
and usually progress to another screen.
5.2.3.2 Output Slewing
In the '1 Year Verification' procedure within Procedure mode, there is a need for the 9100
output to be adjusted ('slewed') around the nominal test point value. This enables the 'slew
error' to be registered in the 9100 internal memory, to appear on printed certificates.
Front Panel Controls — Fine Slewing Adjustments
To provide slewing in single-digit increments, there is an 'ENABLE CURSOR' screen
key on the bottom row of all 'READ — SLEW SOURCE' screens. The effect of pressing
this key is to place the cursors on the least-significant digit of the 'Applied Value',
enabling all the cursor keys, shift keys, spinwheel, and a mouse to operate as for the
Digit Edit facility (refer to Section 3, paras 3.4.4).
